SECTION I: LOGICAL REASONING (Questions 1–50)
Question 1
Editorial: The city council claims that installing new LED streetlights will reduce crime by 20 percent,
citing a study from a neighboring city. However, that study was conducted over only three months and
failed to account for a concurrent increase in police patrols. Therefore, the council's claim is
unsupported.
The editorial's argument proceeds by
A) offering an alternative explanation for the observed effect
B) attacking the character of the city council members
C) demonstrating that the neighboring city's crime rate actually increased
D) showing that LED streetlights are more expensive than traditional lighting
E) appealing to public opinion about street lighting
ANSWER: A
Rationale for each option:
A) Correct. The editorial undermines the council's claim by suggesting that increased police patrols, not
the LED lights, may have caused the crime reduction — an alternative explanation.
B) Incorrect. The argument never mentions or attacks the character of council members.
C) Incorrect. The editorial does not claim the neighboring city's crime increased; it only questions the
causal link.
D) Incorrect. Cost is never discussed.
E) Incorrect. Public opinion is not invoked.
Question 2
,Biologist: Some researchers argue that the decline in bee populations is primarily caused by pesticide
use. However, in regions where pesticide use has been banned for a decade, bee populations continue
to decline at the same rate as elsewhere. Thus, pesticide use cannot be the primary cause of bee
population decline.
The biologist's argument is most vulnerable to criticism on the grounds that it
A) fails to consider that pesticide use may have long-lasting residual effects in the environment
B) relies on anecdotal evidence rather than controlled studies
C) assumes that all bee species are equally affected by pesticides
D) ignores the possibility that bees migrate between regions
E) conflates correlation with causation
ANSWER: A
Rationale for each option:
A) Correct. The argument assumes that banning pesticides would immediately reverse their effects,
ignoring residual contamination that persists for years.
B) Incorrect. The biologist cites regional data, not anecdotes.
C) Incorrect. The argument does not depend on assumptions about all bee species.
D) Incorrect. Migration is not central to the reasoning flaw.
E) Incorrect. The biologist is challenging a causal claim, not making one from correlation.
Question 3
Historian: The traditional view holds that the ancient city of Velora fell due to a prolonged drought.
Recent archaeological evidence, however, shows that Velora's granaries were full at the time of its
abandonment and that its water reservoirs contained significant reserves. Moreover, inscriptions from
neighboring cities describe Velora as being under siege. Thus, the drought theory must be abandoned.
Which one of the following, if true, most seriously weakens the historian's argument?
A) The inscriptions from neighboring cities were written decades after Velora's abandonment.
B) Droughts in the region typically lasted several years.
C) The granaries could have been filled after the siege ended.
D) Velora's reservoirs were designed to store water for up to two years.
E) The siege described in the inscriptions may have been brief and unsuccessful.
ANSWER: C
Rationale for each option:
,A) Incorrect. Even if written later, the inscriptions could still reflect accurate oral traditions.
B) Incorrect. This does not directly address whether drought caused the fall.
C) Correct. If granaries were filled after the siege, the evidence of full granaries does not disprove the
drought theory — the drought could still have caused the initial decline.
D) Incorrect. This supports the idea that water was available, which actually strengthens the historian's
argument.
E) Incorrect. A brief siege could still have caused abandonment when combined with drought.
Question 4
Physician: Patients who take medication X regularly report fewer headaches than those who do not.
However, medication X has no known pharmacological effect on headache pathways. Therefore, the
reduction in headaches must be due to the placebo effect.
The physician's reasoning is flawed because it
A) fails to consider that patients who take medication X regularly may differ in other ways from those
who do not
B) assumes that all headaches have the same cause
C) overlooks the possibility that medication X has unknown effects
D) relies on self-reported data rather than clinical measurements
E) confuses correlation with a placebo effect without ruling out other explanations
ANSWER: E
Rationale for each option:
A) Partially relevant but not the primary flaw.
B) Incorrect. The argument does not assume uniform headache causes.
C) Incorrect. The physician explicitly states X has "no known" effects, leaving room for unknown ones,
but the flaw is broader.
D) Incorrect. Self-reporting is not the central flaw.
E) Correct. The physician jumps to placebo without considering other possibilities (e.g., lifestyle changes,
diet, stress reduction associated with regular medication-taking).
Question 5
Critic: Novelist A's latest work has been praised for its innovative narrative structure. But innovation for
its own sake is not a virtue in literature. A novel should be judged primarily by its emotional depth and
moral insight, neither of which A's work possesses. Therefore, A's latest novel is not a good novel.
The critic's conclusion follows logically if which one of the following is assumed?
, A) Novelist A's earlier works were also lacking in emotional depth.
B) A novel that lacks emotional depth and moral insight cannot be a good novel, regardless of its
narrative innovation.
C) Most critics overvalue narrative innovation.
D) Emotional depth and moral insight are the only qualities that make a novel good.
E) Novelist A intended to prioritize narrative innovation over emotional depth.
ANSWER: B
Rationale for each option:
A) Incorrect. Earlier works are irrelevant to judging the latest novel.
B) Correct. This bridges the gap: if innovation alone doesn't make a novel good, and emotional
depth/moral insight are necessary, then A's novel — lacking those — is not good.
C) Incorrect. What most critics do doesn't determine the logic.
D) Too strong. The argument doesn't require these to be the only qualities, just necessary ones.
E) Incorrect. Authorial intent is not at issue.
Question 6
Economist: When the central bank lowers interest rates, borrowing increases, which stimulates
economic growth. However, in Country Z, interest rates were lowered for three consecutive years, yet
economic growth remained stagnant. Therefore, lowering interest rates does not always stimulate
economic growth.
Which one of the following, if true, most strengthens the economist's argument?
A) Country Z's banking sector was undergoing a major restructuring during those three years.
B) Other countries that lowered interest rates experienced economic growth.
C) Consumer confidence in Country Z was at a historic low during the same period.
D) The central bank of Country Z has a history of ineffective policy implementation.
E) No other major stimulus measures were implemented in Country Z during those three years.
ANSWER: E
Rationale for each option:
A) Weakens — provides an alternative explanation.
B) Incorrect. This would weaken by suggesting rates usually work.
C) Weakens — offers an alternative cause for stagnation.
