, Question 1
Read the following passage: 'The human microbiome, comprising trillions of
microorganisms, plays a critical role in digestion, immunity, and even mood
regulation. Recent studies suggest that disruptions in gut flora, often caused by
prolonged antibiotic use, may contribute to chronic inflammatory conditions.
However, the causal mechanisms remain elusive, and researchers caution
against oversimplifying the microbiome's influence.' Which of the following
best states the main idea of the passage?
A. Antibiotics are the primary cause of chronic inflammatory conditions.
B. The human microbiome is a complex system with far-reaching effects,
but its causal role in disease is not fully understood.
C. Mood regulation is the most significant function of the human
microbiome.
D. Researchers have definitively proven that gut flora disruptions lead to
chronic inflammation.
Correct Answer: B - The human microbiome is a complex system
with far-reaching effects, but its causal role in disease is not fully
understood.
RATIONALE
The passage emphasizes the microbiome's broad influence while
noting that causal mechanisms remain elusive and cautioning against
oversimplification. Option B captures this balanced main idea.
Options A and D overstate certainty, and C isolates a minor detail.
Question 2
In the sentence, 'The politician's speech was so equivocal that even his
staunchest supporters were unsure of his actual stance on the bill,' the word
'equivocal' most nearly means:
A. ambiguous
B. forceful
Page 2
, C. conciliatory
D. repetitive
Correct Answer: A - ambiguous
RATIONALE
The context clue 'even his staunchest supporters were unsure' indicates
that the speech was unclear or open to multiple interpretations.
'Equivocal' means ambiguous or deliberately vague. The other options
do not fit the context of uncertainty.
Question 3
A passage describes a study where patients with chronic pain were given either
a new drug or a placebo. The results showed that the drug group reported a
30% reduction in pain, while the placebo group reported a 15% reduction. The
author concludes: 'These findings suggest that the drug has a modest but real
effect on pain perception.' Which of the following inferences is best supported
by the passage?
A. The placebo effect is not a factor in pain perception.
B. The drug's effect is solely due to participants' belief in its efficacy.
C. The drug produces a greater reduction in pain than a placebo, but the
difference is not large.
D. The drug is ineffective for chronic pain because the reduction was only
30%.
Correct Answer: C - The drug produces a greater reduction in
pain than a placebo, but the difference is not large.
RATIONALE
The passage states the drug group had a 30% reduction versus 15% for
placebo, and the author calls the effect 'modest but real.' Thus, the
drug outperformed placebo but not dramatically. Options A and B
contradict the data, and D misinterprets 'modest' as ineffective.

, Question 4
An author writes: 'It is imperative that we reconsider our reliance on fossil
fuels. The evidence of climate change is overwhelming, and the consequences
of inaction are dire. We must act now to transition to renewable energy
sources.' What is the author's primary purpose?
A. To entertain the reader with a story about climate change.
B. To persuade the reader to support a shift away from fossil fuels.
C. To inform the reader about the history of fossil fuel use.
D. To criticize renewable energy sources as inadequate.
Correct Answer: B - To persuade the reader to support a shift
away from fossil fuels.
RATIONALE
The author uses imperative language ('must act now') and emphasizes
the urgency of transitioning to renewable energy, clearly aiming to
persuade. Options A, C, and D do not align with the call to action and
the negative framing of fossil fuels.
Question 5
Read the following passage: 'While many believe that multitasking increases
productivity, cognitive studies reveal that the brain does not truly perform
multiple tasks simultaneously; instead, it rapidly switches between them. This
switching incurs a 'cognitive cost,' reducing overall efficiency and increasing
errors. Thus, the perceived benefits of multitasking are largely illusory.' Which
of the following statements, if true, would most weaken the author's argument?
A. Some individuals can perform two simple tasks simultaneously
without a drop in performance.
B. Cognitive switching costs are higher for complex tasks than for simple
ones.
C. Multitasking is often required in fast-paced work environments.
D. Training can reduce the cognitive cost of task-switching.
