The correct answer is 1.
Question Explanation:
This question asks which scenario would most likely increase the frequency of human-carnivore conflicts. To determine the best answer, we need to identify the factor that most directly contributes to carnivore-human encounters and conflicts, based on the information in the passage.
Correct Answer Explanation:
(1) Unleashing dogs by pet owners in areas with known high concentrations of large carnivores.
o The passage explicitly states that walking an unleashed dog is a major risky behavior that contributes to human-carnivore conflicts.
o 66% of coyote attacks involve a dog, and unleashed dogs can chase or be chased by carnivores, triggering aggressive responses.
o This directly exacerbates conflicts, making it the most immediate and significant factor in increasing human-carnivore encounters.
Incorrect Answer Explanations:
(2) Addressing the impact of climate change on the availability of resources for wildlife.
o While climate change does contribute to human-carnivore conflicts, the passage states that its correlation still needs to be ironed out.
o It is an indirect factor rather than an immediate cause of increasing conflicts.
(3) Attempting to photograph wild animals from within secured viewing areas in national parks and protected zones.
o The passage mentions people provoking animals while taking pictures as a factor in human-carnivore conflicts, but it refers to people approaching wild animals too closely, not photographing them from designated secured areas.
o If done within protected viewing areas, photography does not necessarily lead to an increase in attacks.
(4) Implementing ‘food waste’ management strategies to prevent wild animals from being attracted to human food sources.
o The passage mentions that carnivores relying on human food lose their natural fear response, which increases conflicts.
o However, implementing food waste management strategies would reduce, not exacerbate, conflicts, making this the opposite of what the question asks.

Question Explanation:
This question asks us to determine how landscape heterogeneity (the mix of farmland and carnivore habitats) impacts human-carnivore conflicts based on insights from Penteriani’s research and Wilkinson’s statement. The best answer should align with the passage’s explanation of how varied landscapes create more opportunities for encounters between humans and carnivores.
Correct Answer Explanation:
(1) The diversity and interspersion of working landscapes with carnivore habitats in rural areas increase the statistical probability of encounters between humans and carnivores.
o The passage states that many low-income countries have “working landscapes” with carnivore habitats, forests, and savannahs interspersed with human activity, which increases the likelihood of encounters.
o Wilkinson explicitly says that these mixed landscapes “create a lot more opportunity for these encounters, just statistically.”
o This directly supports the conclusion that greater landscape diversity and fragmentation increase the probability of human-carnivore conflicts.
Incorrect Answer Explanations:
(2) Low-income countries with vast, contiguous wilderness areas are less prone to human-carnivore conflicts because these areas lack the human presence necessary for such encounters.
o The passage does not state that wilderness areas in low-income countries reduce conflicts; instead, it emphasizes that rural areas with mixed land use increase conflicts.
o Human activity near carnivore habitats leads to more encounters, contradicting this option.
(3) Homogeneous landscapes with uniform agricultural practices are more likely to experience high rates of human-carnivore conflicts due to the predictability of resources.
o The passage does not mention homogeneous landscapes as a cause of increased conflicts.
o It specifically highlights diverse landscapes (forests, savannahs, and farmlands mixed together) as the primary reason for frequent encounters, making this option incorrect.
(4) Landscape heterogeneity, characterized by a mix of farmland and natural habitats, inherently reduces the chances of human-carnivore conflicts by providing more refuge for wildlife away from human activity.
o This is the opposite of what the passage states.
o Instead of reducing conflicts, landscape heterogeneity increases them by bringing humans and carnivores into closer proximity.

Question Explanation:
This question asks which statement, if false, would be inconsistent with the concerns raised in the passage regarding the causes of carnivore-human conflicts. In other words, the false statement should contradict the passage’s key points about factors driving these conflicts.
Correct Answer Explanation:
(2) Climate change has had negligible effects on the frequency of carnivore-human interactions in affected regions.
o The passage explicitly states that experts believe climate change contributes to increased human-carnivore conflicts.
o It provides an example from western India, where a drought forced lions and humans to compete for the same water sources, leading to more lion attacks.
o If statement (2) were false, it would claim that climate change significantly affects these conflicts, which aligns with the passage’s concerns.
o Since this aligns with the passage’s concerns, it means that if (2) were true (i.e., climate change had negligible effects), it would contradict the passage, making it inconsistent with its concerns.
Incorrect Answer Explanations:
(1) Predatory attacks by carnivores are a common occurrence and have steadily increased over the past few decades.
o The passage states that predation-related attacks are rare, accounting for only 17% of cases in North America since 1955.
o If this statement were false, it would mean predatory attacks are uncommon, which is already consistent with the passage’s claims.
o Thus, making (1) false does not contradict the passage, making it an incorrect choice.
(3) Human efforts to avoid risky behaviors around large carnivores have proven effective in reducing conflict incidents.
o The passage states that 50% of human-carnivore attacks could have been avoided if humans reacted differently.
o It also says that engaging in risky behaviors—such as leaving children unattended or walking dogs without a leash—makes attacks more likely.
o If (3) were false, it would mean that human efforts to avoid risky behavior have NOT been effective, which does not contradict the passage’s concerns.
o Thus, (3) being false is still consistent with the passage, making it incorrect.
(4) Carnivores lose their instinctive fear of humans when consistently exposed to human food sources.
o The passage confirms that carnivores can become dependent on human food, leading them to lose their fear of humans, which increases their interactions and conflicts.
o If (4) were false, it would claim that carnivores do NOT lose their instinctive fear, which contradicts the passage.
o However, the passage’s main concerns center on human behavior, climate change, and risky interactions rather than food dependence alone.
o While (4) being false would be inconsistent with some points in the passage, it is not as central as climate change’s role.

Question Explanation:
This question asks about the primary factor that contributes to the habituation of carnivores to human presence according to the passage. Habituation means that carnivores become accustomed to human presence and lose their instinctive fear, which increases human-wildlife conflicts.
Correct Answer Explanation:
(2) The reduction in carnivores’ instinctive fear response, resulting from their reliance upon human-provided food.
o The passage states that carnivores that recognize humans as a means to get food (e.g., at campsites or rubbish bins) become less avoidant of humans.
o The passage specifically notes:
“Losing that instinctive fear response puts them into more situations where they could get into an altercation with a human, which often results in that bear being put down by humans.”
o This means that carnivores’ dependence on human food weakens their natural fear of humans, increasing conflicts.
o Thus, (2) directly aligns with the passage’s argument, making it the correct answer.
Incorrect Answer Explanations:
(1) The natural aggression exhibited by carnivores, exacerbated by human interference, particularly when they are safeguarding their offspring or food sources.
o The passage mentions that carnivores may attack when protecting their young or food but states that such conflicts can be avoided if humans stay away.
o This does not describe a long-term habituation process but rather an instinctual reaction.
o Thus, (1) is incorrect.
(3) The predatory perception of humans as potential prey within the carnivores’ food chain.
o The passage states that predation-related attacks are rare, accounting for only 17% of attacks since 1955.
o It emphasizes that most carnivore-human conflicts arise due to loss of fear rather than predation.
o Since habituation is not linked to predation in the passage, (3) is incorrect.
(4) The increased scarcity of resources due to climate change, forcing carnivores to venture outside their natural habitats in search of sustenance.
o The passage does mention climate change as a factor in increased human-carnivore encounters but does not directly link it to habituation.
o The passage describes a specific case of lions in western India, but this is about resource competition rather than carnivores becoming habituated to humans.
o Thus, (4) is incorrect.

Correct Answer: 2 (Option 3)
The sentence about the hens producing eggs with calcareous shells despite lacking dietary calcium fits best at Option 3 because:
It builds on the mystery introduced in the previous sentence, where no trace of mica was found in the gizzard.
It raises the key scientific question that Kervran later investigates—how the hens could form calcium-rich eggs without an obvious source of calcium.
It acts as a logical transition to the final sentence, which reveals Kervran’s discovery of elemental transmutation.
Incorrect Answers:
A. Option 1
Placing the sentence at the very beginning would be premature because the paragraph has not yet introduced the hens’ unusual behavior of pecking at mica.
The sentence discusses an unexplained phenomenon, but it makes more sense after establishing the hens' behavior and the mystery surrounding their diet.
D. Option 2
The second sentence describes how the hens pecked at specks of mica. Inserting the missing sentence here would disrupt the logical flow because it introduces the issue of egg production before fully discussing the hens' eating habits.
The observation of egg production should come after noting that no mica was found in their gizzards.
C. Option 4
The last sentence explains that it took Kervran years to establish that the chickens were transmuting one element into another.
Placing the missing sentence here would be redundant because the mystery would have already been resolved, making it an unnecessary addition at the end.
The missing sentence introduces a key piece of the puzzle (the eggs containing calcium), which should appear earlier in the paragraph, before the resolution.
2
Correct Answer: 2 (Option 3)
Correct Answer explanation (Option 3):
The missing sentence—"The Europeans did not invent globalization."—fits best at position (3) because the preceding sentences discuss how global interactions and exchanges were already present before European expansion in 1492. The paragraph contrasts the world of 1000 CE with that of 1492 CE, emphasizing that technological differences between civilizations were not as pronounced in the earlier period. The sentence at (3) reinforces this idea by explicitly stating that globalization existed before Europeans played a major role. It then logically leads into the next sentence, which explains how Europeans built upon existing global networks rather than creating them from scratch.
Incorrect Options:
Option 1 (Incorrect)
Placing the sentence at (1) would be too abrupt. The preceding sentences discuss how Southeast Asian economies were reshaped by Chinese demand. Inserting the given sentence here would disrupt the flow of ideas, as it does not directly relate to this economic shift.
Option 2 (Incorrect)
The paragraph states that the exchanges of the year 1000 created trade routes that remained in use after Columbus’s voyage in 1492. Inserting the sentence here would be premature because the discussion has not yet introduced the European expansion. The sentence would be more effective after some contrast has been established between the pre-Columbian and post-Columbian worlds.
Option 4 (Incorrect)
The final sentence of the paragraph argues that globalization must have already been in place for Europeans to expand their markets so quickly after 1492. Placing the missing sentence here would be somewhat redundant, as the idea that globalization preceded European expansion is already implied by the concluding statement.
Thus, Option 3 is the most logical placement because it smoothly transitions from the discussion of technological similarities in the year 1000 to the argument that Europeans did not originate globalization but rather expanded upon existing global networks.

Step-by-Step Breakdown of the Passage:
Key Ideas in the Passage:
States use the DIME model (Diplomacy, Information, Military, Economics) in warfare.
Information warfare is often the first step before military action, targeting telecom data and communication networks.
Governments use cyber troops—actors who manipulate public opinion online via false information and advertising.
The open data policies of the web make this easier, raising privacy and human rights concerns.
Evaluation of the Answer Choices:
Option 1: “Using the DIME model, together with military operations, many governments simultaneously conduct information warfare with the help of cyber troops and routinely monitor telecom data and communications networks.”
Partially correct but misleading:
o The passage distinguishes between information warfare and military operations, stating that information warfare is often conducted before military action.
o The passage does not say that all governments conducting information warfare also deploy military operations at the same time.
o This overstates the connection between military operations and information warfare.
Option 2 (Correct): “As part of conducting information warfare as per the DIME model, many governments routinely monitor telecom data and communications networks, and use cyber troops on social media to manipulate public opinion.”
Accurately captures the passage’s main points:
o Emphasizes information warfare as part of the DIME model.
o Correctly mentions both telecom data monitoring and cyber troops manipu-lating public opinion on social media.
o Concise and complete.
Option 3: “Following the DIME model, many governments have taken advantage of open data policies of the web to deploy cyber troops who manipulate domestic public opinion, using advertising and other strategies to spread false information.”
Partially correct but inaccurate emphasis:
o While open data policies are mentioned, they are not the main focus of the passage.
o The passage does not limit cyber troops to domestic public opinion—they are used in wider low-grade information warfare.
o Overemphasizes open data policies rather than information warfare as a whole.
Option 4: “Governments primarily use the DIME model to deploy cyber troops who practise low-grade information warfare, seeking to manipulate public opinion with the objective of inflicting pain and confusion on their enemies.”
Incorrect emphasis:
o The DIME model includes multiple components, not just information warfare or cyber troops.
o The passage states that governments conduct information warfare before military action, not that they primarily use the DIME model for cyber troops.
o Incorrectly suggests that inflicting pain and confusion is the main goal, when the passage focuses on information control and manipulation.

Correct Answer: 4 (Option 2)
Step-by-Step Breakdown of the Paragraph:
1. Before Blank (1):
• “My fellow night owls, grab a strong cup of coffee and gather around: I have great news.”
• Context:
o This sentence is a direct address to night owls, introducing good news related to them.
• Why the given sentence does not fit here?
o The “great news” is not yet introduced, so adding the given sentence here would be premature.
o The missing sentence is better suited as an explanation or follow-up to the “great news.”
2. Before Blank (2) - Best Fit:
• “For a long time, our kind has been unfairly maligned. Stereotyped as lazy and undisciplined. Told we ought to be morning larks. Advised to go to bed early so we can wake before 5 am and run a marathon before breakfast like all high-flyers seem to do.”
• Context:
o This part discusses negative stereotypes about night owls.
• Why the given sentence fits best here?
o It directly contrasts the negative stereotypes of night owls by stating that science has now proven them superior.
o The sentence “Now, however, we are having the last laugh.” that follows makes sense only if the missing sentence has just introduced the scientific validation of night owls’ superiority.
3. Before Blank (3):
• “It may be a tad more complicated than that. A study published last week, which you may have already seen while scrolling at 1 am, suggests that staying up late could be good for brain power.”
• Context:
o This introduces a study supporting night owls.
• Why the given sentence does not fit here?
o The study is being introduced here, but the missing sentence makes a broader claim about science validating night owls’ superiority, which is better suited earlier.
4. Before Blank (4):
• “Is this study a thinly veiled PR exercise conducted by a caffeine-pill company? Nope, it’s legit.”
• Context:
o This sentence validates the credibility of the study mentioned earlier.
• Why the given sentence does not fit here?
o The paragraph is now discussing the study in detail, so inserting the given sentence at this point would disrupt the flow.

Explanation of the Odd Sentence:
The question requires identifying which sentence does not logically fit into a coherent paragraph on the given topic. Let’s analyze the sentences and how they relate to each other:
1. Sentence 1:
“No known real researcher of human behaviour would say that gender is all nature or all nurture.”
o This introduces a balanced perspective on the nature versus nurture debate about gender. It serves as a foundational statement for the topic.
2. Sentence 2 (Odd One Out):
“The evidence for a biological basis for gender certainly doesn’t mean we should be complacent in the face of sexism.”
o This sentence shifts the focus to sexism, a separate issue not directly connected to the core discussion about the biological versus social construct debate on gender. It introduces a moral or ethical argument that is unrelated to the other sentences.
3. Sentence 3:
“Many people are uncomfortable with the idea that gender is not purely a social construct.”
o This builds on the theme by highlighting public discomfort with the idea of a biological basis for gender. It directly relates to the nature versus nurture discussion.
4. Sentence 4:
“Despite this empirical truth, researchers who study the biological basis of gender often face political pushback.”
o This explains the challenges faced by researchers studying gender’s biological basis, continuing the discussion about societal and political influences.
5. Sentence 5:
“There’s a political preference for gender to be only a reflection of social factors and so entirely malleable.”
o This links the debate to political implications, complementing Sentence 4 and adding depth to the argument about societal preferences for gender explanations.
Coherent Paragraph:
By excluding Sentence 2, the remaining sentences form a logical and cohesive discussion about the nature versus nurture debate on gender and the societal/political reactions to it: 1 → 3 → 4 → 5.
Why Sentence 2 is Odd:
• It shifts the focus from the debate on gender as a biological versus social construct to sexism, which is a separate issue.
• It does not contribute to the discussion of the challenges and societal implications of studying gender from a biological perspective.
• It disrupts the logical flow of the paragraph.

(India was colonised for its spices and gold).
Question Explanation:
This question asks which conclusion CANNOT be reached based on the passage. This means that while three of the options are supported by the passage, one is not. We need to evaluate each option carefully against the information provided.
Correct Answer Explanation:
(2) India was colonised for its spices and gold.
o The passage confirms that spices played a role in colonial expansion, but it never states that gold was a major reason for India’s colonization.
o While spices were an important trade commodity, the passage does not provide any evidence that gold was a primary factor for India’s colonization.
o The passage only mentions gold and silver in a general sense: “Spices never had the enduring allure or power of gold and silver...”
o Thus, the statement that “India was colonised for its spices and gold” cannot be concluded from the passage, making (2) the correct answer.
Incorrect Answer Explanations:
(1) The spice trade was a driver of colonial expansion.
o Supported by the passage: The passage explicitly states that the demand for spices inspired the voyages of Columbus and Vasco da Gama, which launched European colonialism.
o Quote from the passage: “Desire for spices helped fuel European colonial empires to create political, military and commercial networks under a single power.”
o This statement is clearly supported, so (1) is incorrect.
(3) Colonialism was motivated by the demand for spices.
o Supported by the passage: The passage states that spices played a significant role in motivating colonial expansion.
o Quote from the passage: “Still, demand was great enough to inspire the voyages of Christopher Columbus and Vasco Da Gama, launching the first fateful wave of European colonialism.”
o Since colonialism was at least partly motivated by the demand for spices, (3) is supported and is incorrect.
(4) Tobacco was more marketable than spices.
o Supported by the passage: The passage suggests that while spices were important, they did not have the same long-term commercial potential as products like tobacco.
o Quote from the passage: “Spices never had the enduring allure or power of gold and silver or the commercial potential of new products such as tobacco, indigo or sugar.”
o Since the passage directly states that tobacco had greater commercial potential than spices, (4) is supported and is incorrect.

Question Explanation:
This question asks us to identify the one outcome that is likely to happen if a trader brought white peppercorns from India to medieval Europe, while the other three are unlikely based on the passage.
Correct Answer Explanation:
(1) Europeans would doubt the story of pepper harvesting.
o The passage states that Europeans had a mythical belief that pepper trees in India were guarded by serpents and that burning the trees was necessary to drive the snakes away.
o Quote from the passage: “As far back as the 7th century, Europeans thought that pepper in India grew on trees ‘guarded’ by serpents... The only way to harvest pepper was to burn the trees, which would drive the snakes underground.”
o However, white peppercorns are different from black ones, and their presence in Europe would contradict the myth that all pepper had to be harvested through burning.
o This could make Europeans question their earlier beliefs, making (1) the correct answer.
Incorrect Answer Explanations:
(2) The price of spices would decrease.
o Unlikely: The passage does not suggest that introducing white peppercorns would reduce spice prices.
o In medieval Europe, spices were expensive because of their exotic nature and long trade routes, not necessarily because of their color.
o The presence of white peppercorns alone wouldn’t affect pricing significantly, so (2) is incorrect.
(3) Pepper would no longer be considered exotic.
o Unlikely: Even if white peppercorns were brought to Europe, pepper as a whole would still be considered exotic because it came from distant lands.
o The passage emphasizes that spices remained highly prized and exotic well into the Age of Exploration.
o The introduction of a different variety (white peppercorns) would not change Europeans’ perception of its rarity, so (3) is incorrect.
(4) Medieval maps would be used as navigational aids.
o Unlikely: The passage clearly states that medieval maps were highly inaccurate and that geographical knowledge of the East was vague and often based on myths.
o Quote from the passage: “Where spices came from was known in a vague sense centuries before the voyages of Columbus. Just how vague may be judged by looking at medieval world maps.”
o Since medieval maps were not reliable for navigation, their use would not increase, making (4) incorrect.
2
Question Explanation:
This question asks us to identify the one factor that did NOT contribute to the decline in the allure of spices, while the other three did.
Correct Answer Explanation:
(2) Increase in the availability of spices.
o Unlikely to contribute to decline: If spices became more available, it could have reduced their exclusivity, but not necessarily their allure.
o The passage states that spices remained desirable even after the medieval period and continued to drive colonial expansion.
o Quote from the passage: “The taste for spices did continue for a while beyond the Middle Ages. As late as the 17th century, the English and the Dutch were struggling for control of the Spice Islands.”
o This suggests that even when spices became more available, their demand remained high, making (2) the correct answer.
Incorrect Answer Explanations:
(1) The development of refrigeration techniques.
o Contributed to decline: The passage mentions that one reason for the high demand for spices was their use as preservatives before refrigeration existed.
o Quote from the passage: “Refrigeration was not available, and some hot spices have been shown to serve as an anti-bacterial agent.”
o With refrigeration, the need for spices as preservatives declined, reducing their practical necessity.
(3) Changes in European cuisine.
o Contributed to decline: The passage does not explicitly mention this, but we can infer that European cuisine evolved over time, with new ingredients and flavors replacing the heavy reliance on spices.
o As food culture shifted, the demand for exotic spices likely declined.
(4) Changes in the system of medical treatment.
o Contributed to decline: The passage states that spices were initially used as medicine, but as medical knowledge advanced, new treatments and remedies replaced spices.
o Quote from the passage: “Most spices used in cooking began as medical ingredients, and throughout the Middle Ages spices were used as both medicines and condiments.”
o As medicine advanced, spices lost their significance in medical treatments, reducing their demand.
1
Question Explanation:
This question asks us to identify the conclusion that people who heard the myth about pepper trees being guarded by snakes would be least likely to arrive at. The passage describes how medieval Europeans believed that pepper trees in India were protected by serpents, requiring burning the trees to harvest the pepper.
Correct Answer Explanation:
(1) This is why pepper is so hot.
o Least likely conclusion: The story about snakes guarding the pepper trees does not provide any reason why pepper tastes spicy.
o Quote from the passage: “As far back as the 7th century, Europeans thought that pepper in India grew on trees ‘guarded’ by serpents that would bite and poison anyone who attempted to gather the fruit.”
o This explains why pepper is rare and expensive, but it does not connect to the “hotness” or spiciness of pepper.
o Medieval people would not have understood capsaicin or the chemistry behind spiciness, so this would be an unlikely conclusion.
Incorrect Answer Explanations:
(2) Pepper is costly for good reason.
o Likely conclusion: If people believed that harvesting pepper involved battling venomous snakes, they would assume that only a few people could collect it, making it expensive.
(3) It is not advisable to go to India to harvest the pepper themselves.
o Likely conclusion: If people thought that deadly snakes guarded the pepper trees, they would hesitate to risk their lives by traveling to India to harvest it.
(4) It is no surprise that the pepper supply is so limited.
o Likely conclusion: The story suggests that harvesting pepper is dangerous, which could lead people to believe that pepper is scarce.

Step-by-Step Breakdown of the Passage:
1. Key Ideas in the Passage:
• Interdisciplinary collaboration is leading to important scientific discoveries.
• Physicists are working with biologists, sociologists, and others to answer complex questions.
• However, there are challenges in collaboration, such as:
o Physicists discarding data to find broad patterns, while other scientists retain details.
o Many non-physicists being uncomfortable with mathematical models.
• Despite these differences, collaboration continues to be valuable and beneficial.
Evaluation of the Answer Choices:
1. Option 1: “The desire to diversify their research and answer important questions has led to several collaborations between physicists and other social scientists.”
• Partially correct but too narrow:
o The passage talks about physicists collaborating with biologists, sociologists, and others, not just social scientists.
o It ignores the challenges faced in these collaborations.
2. Option 2: “Large data sets and mathematical models in physics research combined with the research methods of non-physicist collaborators have yielded important scientific findings.”
• Inaccurate focus:
o While the passage mentions mathematical models, it does not focus on large data sets as a key aspect of collaboration.
o The passage emphasizes cultural and methodological differences rather than specific tools.
3. Option 3 (Correct): “Despite differences in their research styles, physicists’ research collaborations with scholars from other disciplines have yielded important research findings.”
• Accurately captures the essence:
o Acknowledges both the challenges (differences in research styles) and the benefits (important findings).
o Maintains conciseness and balance, covering all key aspects of the passage.
4. Option 4: “Physicists have successfully buried their differences on research methods applied in other fields in their desire to find answers to baffling scientific questions.”
• Incorrect implication:
o The passage does not say physicists have “buried” their differences—rather, it highlights that challenges still exist.
o It overstates the resolution of differences, whereas the passage only suggests that despite challenges, collaborations are still beneficial.

Question Explanation:
This question asks us to identify the incorrect reason for opposition to open peer reviews. The passage outlines concerns from opponents of making peer reviews public, and we need to determine which option does not align with these concerns.
Correct Answer Explanation:
(3) Leaves the reviewers unexposed to unwarranted and unjustified criticism or comments from others.
o The passage does not state that open peer review protects reviewers from unjustified criticism.
o Instead, it focuses on how open review might deter reviewers from being critical (Option 4) and slow down the review process (Option 2).
o Quote from the passage:
“Opponents of open peer review commonly argue that confidentiality is vital to the integrity of the review process; referees may be less critical of manuscripts if their reports are published, especially if they are revealing their identities by signing them.”
o Nowhere does the passage mention protecting reviewers from external criticism, making Option (3) incorrect.
Incorrect Answer Explanations:
(1) Makes reviewers reluctant to review manuscripts, especially if these are critical of the submitted work.
o Supported by the passage.
o Quote from the passage:
“Some also hold concerns that open reviewing may deter referees from agreeing to judge manuscripts in the first place.”
o This means that reviewers may not want to review papers if their identities are known, so this is a valid concern mentioned in the passage.
(2) Delays the manuscript evaluation process as reviewers would take longer to write their reviews.
o Supported by the passage.
o Quote from the passage:
“Some also hold concerns that open reviewing may deter referees from agreeing to judge manuscripts in the first place, or that they’ll take longer to do so out of fear of scrutiny.”
o This means that reviewers may spend more time writing reviews if they know their comments will be public, leading to delays.
(4) Deters reviewers from producing honest, if critical, reviews that are vital to the sound publishing process.
o Supported by the passage.
o Quote from the passage:
“Referees may be less critical of manuscripts if their reports are published, especially if they are revealing their identities.”
o This means that public peer review could make reviewers hesitant to critique papers honestly, for fear of backlash.
2
Question Explanation:
This question asks us to infer what the author would most likely support based on the passage. The key is to identify the central argument of the passage and determine which option best aligns with the author’s stance.
Correct Answer Explanation:
(2) Greater transparency across the peer review process in academic publishing.
o The main argument of the passage is that peer review is essential but suffers from opacity and inefficiency.
o The author advocates for more transparency to reduce bias, fraud, and inefficiencies in the review process.
o Quote from the passage:
“But the norm should shift from opacity in all cases to opacity only when necessary.”
o This directly supports greater transparency in the review process, making option (2) the best choice.
Incorrect Answer Explanations:
(1) Publicising peer review data rather than the publication of actual reviews.
o While the author acknowledges concerns about publishing full reviews, he does not argue that data should be shared instead of reviews.
o The passage suggests a nuanced approach, not an either/or choice.
o Quote from the passage:
“Even when the content of reviews and the identity of reviewers can’t be shared publicly, perhaps journals could share the data with outside researchers for study.”
o This means that publishing peer review data is a possibility, but not necessarily preferred over publishing reviews.
(3) Preserving the anonymity of reviewers to protect them from criticism.
o The passage acknowledges concerns about anonymity but ultimately advocates for transparency.
o The author does not argue for maintaining absolute reviewer anonymity.
o Quote from the passage:
“Of course, opening up data underlying the reviewing process will not fix peer review entirely, and there may be instances in which there are valid reasons to keep the content of peer reviews hidden and the identity of the referees confidential.”
o This means that while anonymity may sometimes be necessary, the overall argument is for more openness.
(4) More careful screening to ensure the recruitment of content-familiar peer reviewers.
o The passage does not focus on the qualifications of reviewers as the primary issue in peer review.
o The author’s main concern is transparency, not recruitment quality.
o There is no mention of a lack of content-familiar reviewers being a major issue in the passage.

Question Explanation:
This question asks us to identify which reason is NOT mentioned as a motivation for academics reviewing other scholars’ work. We need to analyze the passage and find the one option that does not appear as a reason given by the author.
Correct Answer Explanation:
(1) It is seen as an opportunity to expand their influence in the academic community.
o The passage does not mention that peer reviewers review manuscripts to expand their influence in academia.
o Instead, it focuses on duty, knowledge-sharing, and recognition as motivations.
o Quote from the passage:
“Some do it as a way to keep abreast with developments in their field; some simply see it as a duty to the discipline.”
o There is no reference to influence-building as a stated reason, making option (1) the correct answer.
Incorrect Answer Explanations:
(2) It is seen as a form of service to the academic community.
o The passage explicitly states that reviewing is seen as a duty to the discipline and is essential to the academic system.
o Quote from the passage:
“Some simply see it as a duty to the discipline.”
o This aligns perfectly with option (2), meaning it cannot be the correct answer.
(3) Some use this as an opportunity to publicise their own review work.
o The passage mentions that some academics have started posting their reviews online to claim credit.
o Quote from the passage:
“In recent years, some scientists have begun posting their reviews online, mainly to claim credit for their work.”
o This supports option (3) as a valid reason.
(4) It helps them keep current with cutting-edge ideas in their academic disciplines.
o The passage clearly states that some academics review papers to stay updated on new developments.
o Quote from the passage:
“Some do it as a way to keep abreast with developments in their field.”
o Since this reason is explicitly mentioned, option (4) cannot be the correct answer.
3
Question Explanation:
This question asks us to identify the only reason that is NOT mentioned in favor of making peer review data public. The correct answer will be the one that is not explicitly discussed as a benefit of transparency in the peer review process.
Correct Answer Explanation:
(3) It can tackle the problem of selecting appropriately qualified reviewers for academic writing.
o The passage does not mention that making peer review data public would improve the selection of appropriately qualified reviewers.
o The discussion around bias, fraud, and inefficiencies does not suggest that transparency would ensure better reviewer selection.
o Since the passage does not address this, option (3) is the correct answer.
Incorrect Answer Explanations:
(1) It could address various inefficiencies and fraudulent practices that continue in academic publishing process.
o The passage explicitly states that transparency in peer review data could help eliminate inefficiencies and fraud.
o Quote from the passage:
“Sharing peer review data could help journals stamp out fraud, inefficiency, and systemic bias in academic publishing.”
o Since this benefit is clearly mentioned, option (1) cannot be the correct answer.
(2) It will deal with peer review fraud such as authors publishing bogus reviews of their work.
o The passage mentions that some authors manipulate the system by submitting fake reviews using phony emails.
o Quote from the passage:
“A minority of authors have been known to use phony email addresses to pose as an outside expert and review their own manuscripts.”
o Since peer review transparency could reduce this issue, option (2) cannot be the correct answer.
(4) It would highlight the gender and race biases currently existing in the selection of reviewers.
o The passage discusses bias in reviewer selection, specifically mentioning gender and geographical disparities.
o Quote from the passage:
“A study based on peer review data for nearly 24,000 submissions to the biomedical journal eLife found that women and non-Westerners were vastly underrepresented among peer reviewers.”
o This suggests that making peer review data public would expose these biases, making option (4) incorrect.

Question Explanation:
This question asks us to determine the main point of the first paragraph, which discusses the ripple effects and unintended consequences of technological advancements. The correct option will best summarize how the passage presents these consequences.
Correct Answer Explanation:
(4) The full impact of technological advances cannot be estimated in the short run as the ripple effects often extend far beyond the original intent.
o The passage emphasizes how technological advancements create long-term and unexpected secondary effects—some beneficial, some harmful.
o Quote from the passage:
“The history of any major technological or industrial advance is inevitably shadowed by a less predictable history of unintended consequences and secondary effects.”
o This option correctly captures the idea that technology’s impact is difficult to predict in the short term because its consequences can extend far beyond what was originally intended.
o Since this accurately reflects the passage’s argument, option (4) is the correct answer.
Incorrect Answer Explanations:
(1) It is important to judge an invention not by its immediate outcomes, but by the holistic impact of its secondary effects.
o This implies a value judgment, suggesting that we should judge inventions based on their long-term consequences.
o However, the passage does not make a moral argument about how inventions should be judged—it simply states that unintended consequences exist.
o Since the passage describes rather than prescribes, this is incorrect.
(2) The entire impact of a technological advance should be evaluated by the boost its secondary effects give to generating further technological advances.
o This suggests that the only important secondary effects are those that lead to more technological progress.
o However, the passage discusses both positive and negative consequences—for example, climate change as an unintended consequence of industrialization.
o Since this option ignores the negative consequences discussed in the passage, it is incorrect.
(3) The secondary effects of most major technological advances in the past, especially if they were unintended, have turned out to be beneficial.
o The passage gives both beneficial (printing press leading to microscopes) and harmful (carbon emissions causing climate change) examples of secondary effects.
o Since not all unintended consequences are beneficial, this option misrepresents the argument.
o Therefore, this is incorrect.

Question Explanation:
This EXCEPT question asks us to identify the one statement the author would NOT support, based on the passage. The correct answer will contradict or misrepresent the author’s argument, while the other three options will align with the views expressed in the passage.
Correct Answer Explanation:
(2) While technological advances in the past have had innocuous or beneficial outcomes, more recent advances have the potential to be more threatening globally.
o This statement suggests that past technological advances were mostly harmless or beneficial, while recent ones are uniquely dangerous.
o However, the passage does not make such a distinction. Instead, it presents both positive and negative unintended consequences throughout history—for example:
• The printing press led to eyeglasses and telescopes (beneficial).
• The Industrial Revolution led to carbon-based climate change (harmful).
o The passage also mentions past dangers, such as lead-based fuels and CFCs.
o Since the author does not imply that only modern technology is harmful, this option misrepresents the argument and is the correct answer (i.e., the statement the author would not support).
Incorrect Answer Explanations:
(1) It has become far easier for people today to bring out innovations with dire worldwide consequences than it was earlier.
o The passage states that individuals or small groups can now create scientific advances that could have unintended global consequences (e.g., biotechnology or chemistry).
o Quote from the passage:
“It becomes increasingly possible for individuals or small groups to create new scientific advances… setting off unintended consequences that reverberate on a global scale.”
o Since this directly aligns with the passage, the author would support this view.
o This is incorrect because the author agrees with it.
(3) The by-products of leaded fuel, rather than the fuel itself, were responsible for the build-up of carbon-related gases in the atmosphere.
o The passage discusses how by-products of industrial processes, like CFCs and Ethyl (leaded fuel), have contributed to environmental problems.
o It explicitly mentions the harmful effects of emissions and by-products, meaning the author would likely agree with this statement.
o Since this aligns with the passage, it is incorrect as an answer.
(4) The emissions caused by the large-scale use of leaded fuel ought to have been addressed earlier than they were.
o The passage criticizes the delay in recognizing and addressing environmental issues caused by leaded fuel and industrial emissions.
o Quote from the passage:
“The potential health threats of Ethyl (unleaded fuel) were visible in the 1920s, unlike, say, the long-term effects of atmospheric carbon build-up in the early days of the Industrial Revolution.”
o This suggests that earlier intervention was possible and should have occurred.
o Since the author would support this, this is incorrect as an answer.

Question Explanation:
This EXCEPT question asks us to identify the one option that is NOT listed as an “externality” (unintended consequence) of major technological advances. The correct answer will be something that is not explicitly mentioned in the passage as an externality, while the incorrect options will all be examples given in the passage.
Correct Answer Explanation:
(4) Cooling and de-humidifying of factories through air-conditioning.
o The passage states that air-conditioning was originally invented to control humidity in factories—this was its intended purpose.
o The externality (unintended consequence) was that it enabled mass migration to hot cities like Phoenix and Las Vegas, which was not the original goal of the invention.
o Since cooling and dehumidifying factories was the primary purpose of air-conditioning, it is NOT an externality.
o This is the correct answer because it does not fit the definition of an “externality.”
Incorrect Answer Explanations:
(1) Extension of the phonograph to large-scale recording of music.
o The passage states that Edison invented the phonograph thinking it would be used mainly for dictation.
o However, the unintended externality was that it became widely used for music recordings, which led to a huge industry.
o Since this is explicitly mentioned as an externality, this option is incorrect as an answer.
(2) Build-up of chlorofluorocarbons in the atmosphere.
o The passage mentions CFCs as an unintended consequence of technological advances.
o Quote from the passage:
“Indeed, it is reasonable to see CFCs as a forerunner of the kind of threat we will most likely face in the coming decades...”
o Since this is clearly an externality, this option is incorrect as an answer.
(3) Application of the Jacquard loom to modern IT programming.
o The passage describes how the Jacquard loom, originally created to automate textile weaving, influenced modern programming and computing.
o This was not the loom’s intended purpose, making it an externality.
o Since this is explicitly mentioned as an externality, this option is incorrect as an answer.

Question Explanation:
This question asks about the purpose of mentioning Carrier, Babbage, and Edison in the passage. The correct answer will align with why the author referenced these inventors and their inventions—focusing on their unintended consequences.
Correct Answer Explanation:
(1) These inventors could not have visualized the eventual impact of their inventions on society.
o The passage highlights how Carrier’s air-conditioning, Babbage’s computing, and Edison’s phonograph ended up having unexpected societal impacts that the inventors did not foresee.
o Carrier invented air-conditioning for factories, but it enabled the growth of cities like Phoenix and Las Vegas.
o Babbage’s mechanical computer was influenced by textile machinery, which later evolved into modern computing.
o Edison saw the phonograph as a tool for dictation, but it revolutionized the music industry.
o Key phrase from the passage:
“Oftentimes the secondary effects seem to belong to an entirely different sphere of society.”
o This directly supports the idea that these inventors could not have predicted the full impact of their inventions.
o This is the correct answer.
Incorrect Answer Explanations:
(2) The secondary effect of past inventions mostly resulted in the creation of new inventions.
o Incorrect because the passage does not claim that all secondary effects lead to new inventions.
o While some inventions (e.g., the printing press ’! lenses ’! microscopes/telescopes) led to new technologies, others (e.g., air-conditioning ’! urban migration) caused social changes rather than new inventions.
(3) Inventions typically end up being used for entirely different purposes than the intended ones.
o Partially correct, but too extreme—the passage shows that some inventions are used differently than intended (e.g., phonograph), but others simply had additional effects (e.g., air-conditioning).
o The passage does not claim that inventions always end up being used differently, just that they often have unintended consequences.
(4) Despite the original intention, the unintended consequences of their inventions were largely beneficial.
o Incorrect because the passage does not argue that unintended consequences are always beneficial.
o Some examples are positive (e.g., air-conditioning enabling new cities), but the passage also warns about harmful externalities, such as carbon emissions and climate change.

Step-by-Step Breakdown of the Passage:
1. Key Ideas in the Passage:
• John Cleese argues that comedians today lack the freedom to be funny.
• Creativity requires an atmosphere of freedom—comedians should be able to explore ideas spontaneously without constant self-censorship.
• Fear of offending people is stifling creativity, as comedians hesitate to say things that might get them into trouble.
• This self-censorship limits originality and kills creativity.
Evaluation of the Answer Choices:
1. Option 1: “Comedians are being prevented from saying what they want and that is the death of this art form.”
• Too extreme and inaccurate:
o The passage does not say comedians are completely “prevented” from saying what they want.
o Cleese discusses self-censorship rather than outright prohibition.
o Also, the passage is about creativity being stifled, not the death of comedy as an art form.
2. Option 2: “Comedians must not check what they think and say. They must go where no one has gone before.”
• Too simplistic and misleading:
o The passage does not say comedians should never check what they think and say.
o The focus is on the freedom to create, not recklessly saying anything without consideration.
o This option oversimplifies Cleese’s point about how fear of consequences hinders creativity.
3. Option 3 (Correct): “Freedom and creativity are essential for comedy. Fear about offending people hinders originality.”
• Accurately captures the essence of the passage:
o Emphasizes both key ideas—the need for freedom in creativity and how fear of offending people stifles originality.
o Concise, precise, and well-balanced.
4. Option 4: “Creativity and critical thinking cannot work together. Comedians must first be creative, and later be critical.”
• Incorrect interpretation:
o The passage does not argue that creativity and critical thinking cannot coexist.
o Cleese’s concern is about self-censorship limiting spontaneity, not a contrast between creativity and critical thinking.
o This misrepresents his argument.

Explanation:
The sentences discuss the development, approval, and potential benefits of cultivated meat in the UK, particularly focusing on innovations and their impact. Let’s evaluate each sentence:
Sentence 1:
“The UK is a world leader in developing cultivated meat and the approval of a cultivated pet food is an important milestone.”
• This sentence introduces the topic of cultivated meat and highlights a milestone in its development. It aligns with the rest of the sentences.
This fits in the coherent paragraph.
Sentence 2:
“If we’re to realise the full potential benefits of cultivated meat the government must invest in research and infrastructure.”
• This sentence discusses the potential benefits of cultivated meat and emphasizes the need for government investment to fully realize its potential. It complements the other sentences.
This fits in the coherent paragraph.
Sentence 3:
“The first UK applications for cultivated meat produced for humans remain under assessment with the Food Standards Agency.”
• This sentence discusses the regulatory status of cultivated meat in the UK, which is relevant to the topic.
This fits in the coherent paragraph.
Sentence 4:
“The previous UK government had been looking at fast-tracking the approval of cultivated meat for human consumption.”
• This sentence refers to past actions by the UK government, but it introduces a tangential timeline detail (previous government actions) rather than focusing on the current state of cultivated meat and its potential benefits. It does not align well with the other sentences’ themes.
This is the odd sentence.
Sentence 5:
“It underscores the potential for new innovation to help reduce the negative impacts of intensive animal agriculture.”
• This sentence connects cultivated meat to its broader societal impact by addressing how it can mitigate the harmful effects of traditional animal agriculture.
This fits in the coherent paragraph.
Coherent Paragraph:
1 → 5 → 3 → 2
This sequence provides a logical flow, introducing the UK’s leadership in cultivated meat (1), discussing its potential benefits (5), highlighting regulatory progress (3), and emphasizing the need for government investment (2).
Why Sentence 4 is the Odd One:
Sentence 4 introduces a less relevant detail about the previous government and its approach to fast-tracking approval, which does not align with the primary focus on current developments, benefits, and regulatory progress.
