Passage 1: Literature

The old house at the end of Maple Street had been empty for so long that the neighbours had begun to think of it as part of the landscape, as permanent and unchanging as the oak tree in the front yard. But when Clara stepped through the front door for the first time in twenty years, the house did not greet her with silence. Instead, it offered a kind of whispered chorus: the creak of floorboards underfoot, the tap of a branch against a window, the distant groan of a pipe in the wall. These sounds were not hostile — they were familiar, as though the house recognised her and was, in its own way, welcoming her home. Clara placed her hand on the newel post at the base of the staircase and felt the worn groove where generations of hands had rested. She climbed slowly, each step releasing a small sigh from the wood, until she reached the second floor. There, in the room that had once been hers, she found a single item left behind: a small porcelain bird, perched on the windowsill where she had placed it the day before her family departed. It was dusty but intact, and when she picked it up, the weight of it in her palm was heavier than she remembered, though the bird itself had not changed at all.

Q1. Which quotation from the passage most effectively supports the claim that the house has personality or agency?

A) “the house did not greet her with silence” B) “the neighbours had begun to think of it as part of the landscape” C) “as permanent and unchanging as the oak tree in the front yard” D) “the branch against a window, the distant groan of a pipe”

Q2. In the context of the passage, the word “hostile” most nearly means

A) unfamiliar B) threatening C) vacant D) damaged

Q3. The narrator’s description of Clara’s experience primarily serves to

A) illustrate how neglected buildings deteriorate over time B) convey the emotional significance of returning to a childhood home C) critique neighbours for failing to maintain abandoned properties D) contrast urban and rural attitudes toward abandoned houses

Q4. The passage suggests that Clara’s perception of the porcelain bird has changed because

A) the bird has been physically altered by time B) Clara no longer values sentimental objects C) Clara’s emotional relationship to the past has deepened D) the bird was moved from its original location

Cross-Text Reference Passage

Clara’s sister, Maren, visited the house the following week. She walked through every room in fifteen minutes, noted the cracked plaster and peeling wallpaper, and announced that it would cost a fortune to renovate. “It’s just a house,” she said, shrugging. “Brick and wood and dust.” She did not linger in any room, did not touch the newel post, did not climb the stairs. When Clara asked if she wanted to see the second floor, Maren glanced at her watch and said she had an appointment.

Q5. Which statement best describes the relationship between Clara’s experience in Passage 1 and Maren’s experience in the cross-text passage?

A) Both characters focus on the physical deterioration of the house B) Clara finds personal meaning in the house, while Maren sees only its material value C) Maren feels a stronger emotional connection than Clara does D) Both characters are equally eager to renovate the house

Q6. Compared to Clara’s perspective, Maren’s description of the house as “just a house” and “brick and wood and dust” serves primarily to

A) demonstrate Maren’s practical expertise in home renovation B) highlight the difference between emotional attachment and pragmatic detachment C) suggest that Maren is correct and Clara is being unrealistic D) foreshadow a future conflict between the sisters over ownership

Annotated Answers — Passage 1

Q1. Correct answer: A

Choice	Analysis
A	The phrase “did not greet her with silence” attributes the deliberate action of greeting to the house, implying it possesses agency. This is the strongest evidence for the claim.
B	This describes the neighbours’ perception of the house, not the house’s own qualities. It suggests passivity, not personality.
C	Compares the house to a tree, emphasising its permanence but not its personality or agency.
D	Lists sounds but presents them as ordinary physical phenomena, not as actions of an animate entity.

Q2. Correct answer: B

Choice	Analysis
A	”Unfamiliar” does not fit the context — the sounds are described as “familiar” in the very next sentence.
B	”Hostile” means showing ill will or aggression. The passage says the sounds were “not hostile,” meaning they were not threatening or aggressive. The narrator is clarifying the sounds are welcoming, not menacing.
C	”Vacant” does not make sense as a substitute for “hostile” in describing sounds.
D	”Damaged” is a physical condition and cannot describe the attitude of sounds.

Q3. Correct answer: B

Choice	Analysis
A	The passage does not focus on deterioration — it notes the house is “empty” but emphasises familiarity and continuity, not decay.
B	The details (the worn groove on the newel post, the whispered chorus, the porcelain bird) all serve to convey Clara’s emotional reconnection with her past. The passage is about the significance of returning, not about the building’s condition.
C	The neighbours are mentioned only in passing and are not critiqued.
D	No urban/rural contrast is present or implied.

Q4. Correct answer: C

Choice	Analysis
A	The passage states the bird is “dusty but intact” and “had not changed at all,” ruling out physical alteration.
B	Clara picks up the bird and notices its weight, suggesting she still values it.
C	The passage says the bird “had not changed at all” but felt “heavier than she remembered.” Since the bird itself is unchanged, the difference must lie in Clara’s perception — the weight of memory and time makes the object feel more significant.
D	The passage states the bird is on the same windowsill Clara originally placed it.

Q5. Correct answer: B

Choice	Analysis
A	Clara does not focus on deterioration; Maren does. The passages are contrasting, not parallel.
B	Clara engages with the house emotionally (touching the newel post, listening to sounds, treasuring the bird), while Maren focuses only on practical concerns (cost, materials, appointments). This captures the central contrast.
C	Maren shows no emotional connection — she rushes through and dismisses the house as “just a house.”
D	Neither character expresses eagerness to renovate. Clara is reconnecting; Maren is dismissing.

Q6. Correct answer: B

Choice	Analysis
A	Maren does not demonstrate expertise — she merely notes visible damage and estimates cost.
B	Maren’s reduction of the house to raw materials (“brick and wood and dust”) contrasts sharply with Clara’s experience of it as a living repository of memory. The phrase highlights the gulf between pragmatic detachment and emotional attachment.
C	The passages do not establish that either sister is “correct” — they present two different perspectives.
D	While conflict is possible, the passage gives no textual evidence of ownership disputes. This is speculation beyond the text.

Passage 2: History / Social Studies

The debate over whether social media platforms should be legally classified as publishers or as neutral intermediaries has intensified in recent years. Under current US law, Section 230 of the Communications Decency Act shields platforms from liability for content posted by their users, treating them more like telephone companies than like newspapers. Proponents of reform argue that this framework is outdated: modern platforms curate content through algorithms, recommend posts, and remove material they deem objectionable — activities that more closely resemble editorial decisions than neutral conveyance. Senator Marcus Webb has proposed legislation that would condition Section 230 protections on platforms demonstrating that their content moderation systems are “viewpoint neutral.” Critics counter that Webb’s proposal would paradoxically force platforms to over-moderate, removing legitimate speech to avoid lawsuits. Moreover, they argue, the sheer volume of user-generated content makes true viewpoint neutrality practically impossible to verify. The algorithmic curation that reformers cite as evidence of editorial intent is, according to computer scientists, driven primarily by engagement metrics rather than ideological preferences.

Q7. Which finding, if true, would most strengthen the critics’ argument that Webb’s proposal would lead to over-moderation?

A) Platforms that face potential liability for user content spend more on human moderators B) Platforms in countries without Section 230-style protections remove 40% more user content C) Most users support stronger content moderation on social media D) Engagement-based algorithms correlate with increased time spent on platforms

Q8. The passage suggests that proponents of reform and critics of reform disagree primarily about

A) whether Section 230 should be repealed entirely B) whether algorithmic curation constitutes editorial activity C) whether computer scientists understand how algorithms work D) whether social media platforms are popular among young people

Q9. Based on the passage, which claim would the author of the passage most likely agree with?

A) Webb’s legislation should be adopted without modification B) The current Section 230 framework adequately addresses modern concerns C) The debate involves legitimate concerns on both sides that are not readily resolved D) Platforms should be treated identically to traditional print publishers

Q10. The passage presents the computer scientists’ view in order to

A) refute the reformers’ argument that algorithms demonstrate editorial bias B) endorse the reformers’ claim that platforms exercise editorial control C) suggest that engagement metrics are themselves a form of bias D) propose an alternative to both the reformers’ and critics’ positions

Q11. Which piece of evidence from the passage most directly supports the claim that platforms currently engage in activities resembling editorial decisions?

A) “Section 230 of the Communications Decency Act shields platforms from liability” B) “modern platforms curate content through algorithms, recommend posts, and remove material” C) “the sheer volume of user-generated content makes true viewpoint neutrality practically impossible” D) “engagement metrics rather than ideological preferences”

Q12. The word “neutral” as used in the phrase “viewpoint neutral” most nearly means

A) disinterested B) unbiased C) colourless D) inactive

Annotated Answers — Passage 2

Q7. Correct answer: B

Choice	Analysis
A	More spending on moderators does not directly show over-moderation — it could directly mean more thorough moderation.
B	This provides direct empirical evidence: platforms without liability shields remove significantly more content, suggesting that removing liability protection leads to over-moderation. This is exactly the critics’ concern applied to Webb’s proposal.
C	User support for moderation is irrelevant to whether Webb’s proposal would cause over-moderation.
D	This supports neither side of the debate about over-moderation.

Q8. Correct answer: B

Choice	Analysis
A	Neither side calls for full repeal — reformers want to condition protections on neutrality; critics defend the current framework.
B	Reformers argue that algorithmic curation “more closely resemble[s] editorial decisions,” implying it constitutes editorial activity. Critics don’t directly dispute this but argue the consequences of treating it as such are harmful. The central disagreement is whether curation = editorial action.
C	The passage does not question whether computer scientists understand algorithms.
D	Popularity is not discussed in the passage.

Q9. Correct answer: C

Choice	Analysis
A	The author presents critics’ objections to Webb’s proposal, suggesting reservations.
B	The author notes that reformers argue the framework is “outdated,” which the author does not refute.
C	The passage presents reformers’ arguments fairly (algorithmic curation resembles editorial activity) and critics’ arguments fairly (over-moderation risk, practical impossibility of verifying neutrality). The balanced presentation suggests the author sees merit on both sides.
D	The author never suggests treating platforms identically to print publishers.

Q10. Correct answer: A

Choice	Analysis
A	Reformers claim that algorithmic curation demonstrates editorial intent. The computer scientists’ view — that algorithms are driven by engagement metrics, not ideology — undermines this claim by providing an alternative explanation for curation behaviour.
B	This would contradict the scientists’ view, not explain its purpose in the passage.
C	The passage presents the scientists’ view as contradicting the reformers’ argument, not as introducing a new form of bias.
D	The passage does not present the scientists as proposing an alternative legislative framework.

Q11. Correct answer: B

Choice	Analysis
A	This describes the legal protection, not evidence of editorial activity.
B	Curation through algorithms, recommending posts, and removing material are all described as activities that “more closely resemble editorial decisions than neutral conveyance.” This is the direct evidence.
C	This supports the critics’ argument about the difficulty of neutrality, not the claim that platforms act like editors.
D	This undermines the claim of editorial intent by providing an alternative explanation for curation.

Q12. Correct answer: B

Choice	Analysis
A	”Disinterested” means impartial in a personal sense but carries connotations of lack of concern; “viewpoint neutral” is about fairness, not apathy.
B	”Viewpoint neutral” means not favouring any particular viewpoint — treating all perspectives equally. “Unbiased” captures this meaning precisely.
C	”Colourless” means lacking distinctive character; it does not convey the concept of fairness across viewpoints.
D	”Inactive” means not active; viewpoint neutrality is about how moderation is applied, not whether it occurs at all.

Passage 3: Science

Marine biologists studying the impact of ocean acidification on coral reef ecosystems have documented measurable changes in coral growth rates across three reef zones over a ten-year period. The researchers measured average seawater pH and mean annual coral growth (in millimetres per year) at each site. Their findings are summarised below.

Reef Zone	Year 1 pH	Year 10 pH	Year 1 Growth (mm/yr)	Year 10 Growth (mm/yr)
Shallow	8.10	7.95	12.4	9.8
Mid-depth	8.08	7.98	10.6	8.7
Deep	8.06	8.01	8.2	7.1

The researchers hypothesised that lower pH would correlate with reduced coral growth. They noted that the shallow zone experienced the greatest pH decrease (0.15) and also showed the largest decline in growth rate (2.6 mm/yr). However, they also observed that water temperature in the shallow zone had increased by 1.2°C over the study period, whereas the deep zone saw only a 0.3°C increase. The biologists cautioned that the growth decline could therefore be driven by temperature, pH, or an interaction between the two factors.

Q13. According to the table, which reef zone had the highest coral growth rate at the start of the study?

A) Deep B) Mid-depth C) Shallow D) All zones had equal growth rates

Q14. Which statement about the relationship between pH change and growth change is supported by the data in the table?

A) The zone with the smallest pH decrease showed the largest growth decline B) The zone with the largest pH decrease showed the largest growth decline C) pH and growth rate are inversely related at a single point in time D) Growth rate is determined solely by pH levels

Q15. The researchers’ caution at the end of the passage is intended to address which potential flaw in their study?

A) The study period was too short to draw conclusions B) Multiple variables may be contributing to the observed effect C) The measurement instruments may have been unreliable D) Coral growth rates vary seasonally and annual averages mask variation

Q16. If a new study found that coral in a controlled laboratory environment with lowered pH but stable temperature showed no significant growth decline, this finding would most directly support which conclusion?

A) Temperature is the sole cause of the growth decline observed in the study B) Ocean acidification has no effect on coral growth C) Temperature, rather than pH alone, may explain the growth decline D) Laboratory conditions are fundamentally incompatible with marine biology

Q17. Based on the data, approximately what percentage decline in growth rate did the mid-depth zone experience over the study period?

A) 8% B) 18% C) 22% D) 26%

Q18. The passage states that the researchers hypothesised “that lower pH would correlate with reduced coral growth.” Based on the data, this hypothesis is best described as

A) fully supported, because all zones showed both pH decreases and growth declines B) partially supported, because the observed trend is consistent but confounding variables prevent definitive conclusions C) refuted, because the deep zone showed only a small pH change D) irrelevant, because the researchers did not actually test this hypothesis

Annotated Answers — Passage 3

Q13. Correct answer: C

Choice	Analysis
A	Deep zone Year 1 growth: 8.2 mm/yr.
B	Mid-depth Year 1 growth: 10.6 mm/yr.
C	Shallow zone Year 1 growth: 12.4 mm/yr, the highest of the three zones.
D	The table shows three different growth rates.

Q14. Correct answer: B

Choice	Analysis
A	The deep zone had the smallest pH decrease (0.05) and the smallest growth decline (1.1), so this is false.
B	The shallow zone had the largest pH decrease (0.15) and the largest growth decline (2.6 mm/yr). This is directly supported by the data.
C	The passage does not provide data to evaluate pH vs. growth at a single point in time across zones — it tracks change over time.
D	”Solely” is too strong; the researchers themselves identify temperature as a possible confound.

Q15. Correct answer: B

Choice	Analysis
A	Ten years is not described as insufficient; the caution addresses variables, not duration.
B	The researchers explicitly state that “the growth decline could therefore be driven by temperature, pH, or an interaction between the two factors.” This is an acknowledgment that multiple variables may be at play.
C	There is no mention of instrument reliability concerns.
D	Seasonal variation is not discussed.

Q16. Correct answer: C

Choice	Analysis
A	”Sole cause” is too strong — the lab finding eliminates pH as a sole cause but does not establish temperature as the sole cause either.
B	The lab finding doesn’t prove pH has no effect — only that lowered pH without temperature change didn’t reduce growth in this specific study.
C	If lowering pH alone (without a temperature change) does not reduce growth, then the growth declines observed in the field study (where temperature also changed) may be attributable to temperature rather than pH. This is the most directly supported conclusion.
D	This is an overgeneralisation not supported by the passage.

Q17. Correct answer: B

Choice	Analysis
A	Incorrect calculation.
B	Mid-depth decline: $(10.6 - 8.7) / 10.6 = 1.9 / 10.6 \approx 0.179$, or approximately 18%.
C	This is the result if you use the wrong denominator or miscalculate.
D	This would be the approximate decline for the shallow zone: $(12.4 - 9.8) / 12.4 = 2.6 / 12.4 \approx 0.21$, or roughly 21%, not 26%.

Q18. Correct answer: B

Choice	Analysis
A	”Fully supported” is too strong because the researchers themselves identify confounding variables.
B	The trend is consistent with the hypothesis (all zones showed pH decreases and growth declines), but the confounding variable of temperature means the hypothesis cannot be definitively confirmed. “Partially supported” is the most accurate description.
C	The deep zone’s small pH change does not refute the hypothesis — it directly provides a weaker data point.
D	The researchers explicitly state the hypothesis and then present data relevant to it.

Passage 4: Paired Passages — History / Social Studies

Passage A

The expansion of college athletics into a multi-billion-dollar commercial enterprise has created an untenable contradiction. Universities generate enormous revenue from television contracts, merchandise sales, and ticket sales — revenue that depends overwhelmingly on the labour of student-athletes who are, in most cases, prohibited from earning any compensation beyond their scholarships. The National Collegiate Athletic Association (NCAA) has long defended this arrangement as essential to preserving the “amateur spirit” of college sports. But this argument is difficult to sustain when a university’s football coach earns $8 million annually while the players who make that salary possible cannot accept a free meal from a booster. The current system is not amateurism — it is exploitation dressed in idealism.

Passage B

Proponents of compensating college athletes often point to the revenue generated by major sports programmes as evidence of unfairness. But this argument ignores the fundamental purpose of the university. An institution of higher education exists to advance knowledge and develop human capital, not to operate as a minor league for professional sports. The vast majority of college athletic programmes operate at a deficit, subsidised by tuition dollars and general university funds. If student-athletes were to receive salaries, the burden would fall on students who will never play a single minute of collegiate sport. Moreover, introducing compensation would fundamentally alter the relationship between athlete and institution, transforming students into employees and education into a secondary concern.

Q19. Which statement best describes the primary point of disagreement between the authors of Passage A and Passage B?

A) Whether college athletes currently receive scholarships B) Whether the current system of college athletics can be morally justified C) Whether college sports generate revenue for universities D) Whether professional sports leagues should draft younger players

Q20. Passage A would most likely characterise the argument in Passage B about the “fundamental

purpose of the university” as

A) a necessary corrective to the commercialisation of college sports B) an evasion of the ethical problem posed by unpaid labour in a profitable enterprise C) a compelling argument that should determine NCAA policy D) an accurate description of how most universities actually operate

Q21. Both authors would most likely agree that

A) college athletes should receive salaries equal to professional players B) the NCAA’s current regulations need significant revision C) revenue from college sports is distributed inequitably D) major college athletic programmes generate substantial revenue

Q22. The author of Passage B uses the statistic about “the vast majority of college athletic

programmes” primarily to

A) demonstrate that most athletes are not talented enough for professional sports B) challenge the assumption that all college sports programmes are financially successful C) argue that college athletes should focus on academics rather than athletics D) suggest that most universities should eliminate athletic programmes

Annotated Answers — Passage 4

Q19. Correct answer: B

Choice	Analysis
A	Both passages acknowledge that athletes receive scholarships; this is not a point of disagreement.
B	Passage A argues the system is “exploitation” and unjust; Passage B argues the current model serves the educational mission and that changing it would be harmful. The core disagreement is whether the system can be morally justified.
C	Both authors acknowledge that major sports generate revenue; they disagree on the implications, not the fact.
D	Neither passage discusses professional drafting.

Q20. Correct answer: B

Choice	Analysis
A	Passage A would not agree with Passage B’s position.
B	Passage A argues that the revenue generated by athletes creates a moral obligation that cannot be dismissed by appealing to the “amateur spirit” or the educational mission. Passage B’s appeal to the university’s “fundamental purpose” would look to Passage A like a way of avoiding the ethical issue of unpaid labour.
C	Passage A advocates for change, not for maintaining the current NCAA policy.
D	Passage A is arguing about the specific injustice of the revenue model, not about how most universities operate.

Q21. Correct answer: D

Choice	Analysis
A	Neither author advocates for professional-level salaries.
B	Passage A wants revision toward compensation; Passage B wants to preserve the current model. They disagree on the direction of revision.
C	Passage B would likely argue that the current distribution (where revenue supports non-revenue sports) is appropriate.
D	Passage A explicitly states that universities “generate enormous revenue”; Passage B does not dispute this but focuses on the majority of programmes that operate at a deficit. Both acknowledge that major programmes generate substantial revenue.

Q22. Correct answer: B

Choice	Analysis
A	The statistic is about financial performance of programmes, not athlete talent.
B	Passage B cites the fact that “the vast majority of college athletic programmes operate at a deficit” to counter the reformers’ focus on profitable programmes. The statistic challenges the assumption (implied by Passage A) that the revenue model is typical of all college sports.
C	While Passage B values academics, this statistic is about finances, not academic priorities.
D	Passage B does not advocate eliminating athletic programmes.

Passage 5: Grammar and Editing

Over the past decade, the field of artificial intelligence (AI) have undergone a remarkable transformation. Breakthroughs in machine learning, particularly in deep neural networks, has enabled systems that can recognise images, translate languages, and generate human-like text. These developments are largely driven by three factors: the availability of massive datasets, increases in computing power, and advances in algorithm design. However, researchers caution that current AI systems remain narrow in capability. They can perform specific tasks impressively but lack the general reasoning skills that humans possess. Dr. Elena Vasquez, a leading AI researcher at MIT, argues that the field must address ethical concerns proactively. For instance, her recent study examined bias in facial recognition algorithms and found significant accuracy disparities across demographic groups. The study’s findings have prompted calls for regulatory frameworks. Furthermore, some critics contend that AI development is proceeding too quickly. This rapid pace, they warn, could outstrip society’s ability to establish appropriate safeguards.

Q23. What correction, if any, should be made to the underlined word “have” in the first sentence (“the field of artificial intelligence (AI) have undergone”)?

A) “has” (no change to subject) B) “have” is correct as written C) “having” D) “has” (but “field” should be changed to “fields”)

Q24. What correction, if any, should be made to the underlined word “has” in the second sentence (“particularly in deep neural networks, has enabled”)?

A) “have” B) “has” is correct as written C) “have been” D) “having”

Q25. What correction, if any, should be made to the underlined transition word “However” before “researchers caution that current AI systems remain narrow in capability”?

A) “Therefore” B) “Additionally” C) “However” is correct as written D) “Meanwhile”

Q26. The underlined pronoun “They” in the sentence “They can perform specific tasks impressively” is ambiguous. Which revision best resolves the ambiguity?

A) “AI systems can perform” B) “These can perform” C) “Both can perform” D) “The systems can perform”

Q27. Which of the following sentences, if inserted after the sentence about Dr. Vasquez’s study (“The study’s findings have prompted calls for regulatory frameworks”), would most logically continue the discussion?

A) Machine learning techniques were first developed in the 1950s B) Critics argue that without regulation, biased algorithms could perpetuate discrimination in hiring, lending, and law enforcement C) The cost of training large AI models has increased dramatically in recent years D) Many universities now offer degree programmes in artificial intelligence

Q28. Which of the following is the most concise version of the sentence “This rapid pace, they warn, could outstrip society’s ability to establish appropriate safeguards”?

A) They warn this pace could outstrip society’s safeguards B) This pace could, they warn, outstrip society’s ability to establish appropriate safeguards C) Critics warn rapid AI development may outpace the creation of adequate safeguards D) Society might not be able to keep up with how fast AI is moving, according to critics

Annotated Answers — Passage 5

Q23. Correct answer: A

Choice	Analysis
A	The subject is “the field” (singular), so the verb must be “has.” The prepositional phrase “of artificial intelligence” does not change the subject. “Field” should remain singular because the passage discusses a single field.
B	”Have” is a plural verb and does not agree with the singular subject “field.”
C	”Having” creates a participial phrase that would make the sentence grammatically incomplete.
D	Changing “field” to “fields” would alter the meaning — the passage is about one field, not multiple.

Q24. Correct answer: B

Choice	Analysis
A	”Breakthroughs” is plural, but it is not the subject of “has enabled.” The subject is the entire noun clause or the situation described — more precisely, the singular antecedent of the sentence is the collective concept of breakthroughs as a single development. However, the most important point is that “breakthroughs…has” is grammatically defensible as a collective subject. On the SAT, this sentence could be rewritten, but “has enabled” treats the development as a singular unified event, which is acceptable.
B	”Has enabled” is correct. The verb refers to the overall development — the breakthroughs collectively have enabled the systems. In SAT conventions, this collective treatment is acceptable.
C	”Have been enabled” shifts to passive voice and changes the meaning (something enabled the breakthroughs, not the other way around).
D	”Having” creates an awkward construction without a main clause.

Q25. Correct answer: C

Choice	Analysis
A	”Therefore” implies a conclusion follows, but the passage is presenting a contrast between the impressive capabilities and the limitations — not a consequence.
B	”Additionally” implies the limitations are being added to a list of achievements, but the sentence shifts to a qualification of the previous claims.
C	”However” correctly signals a contrast: despite the impressive breakthroughs, the systems are still limited. This matches the logical relationship between the sentences.
D	”Meanwhile” suggests simultaneous events, but this is a logical contrast, not a temporal relationship.

Q26. Correct answer: A

Choice	Analysis
A	Replacing “They” with “AI systems” eliminates ambiguity by naming the specific antecedent. The reader no longer has to determine whether “They” refers to researchers, datasets, or algorithms.
B	”These” is still ambiguous — it could refer to any preceding plural noun.
C	”Both” implies exactly two antecedents, which is not the case.
D	”The systems” is an improvement but less precise than naming “AI systems” explicitly.

Q27. Correct answer: B

Choice	Analysis
A	The history of machine learning is irrelevant to the current discussion about regulation and bias.
B	The preceding sentence discusses calls for regulatory frameworks prompted by bias findings. This sentence extends that discussion by explaining why regulation matters — biased algorithms could cause real harm in specific domains. The logical connection is direct.
C	Training costs are unrelated to the regulatory/bias discussion.
D	University programmes are off-topic in a discussion about regulation and ethical concerns.

Q28. Correct answer: C

Choice	Analysis
A	Removing “society’s ability to establish appropriate safeguards” changes the meaning.
B	This is barely shorter than the original and does not achieve meaningful conciseness.
C	”Critics warn rapid AI development may outpace the creation of adequate safeguards” conveys the same meaning in fewer words by replacing wordy phrases (“outstrip society’s ability to establish appropriate safeguards” becomes “outpace the creation of adequate safeguards”).
D	This is longer, more informal, and less precise than the original.
