Scientists often study modern-day primates in an attempt to better understand the behavior and lifestyle of their now-extinct primate ancestors. This is a questionable technique, however, as primate groups have not always been exposed to the same types of external stimuli. Most primates now being observed have been seriously impacted by the loss of their former habitat due to deforestation.
Which of the following, if true, most seriously undermines the argument above?
(A) By studying the response of a primate group to any external factors, scientists can better predict how other primates would respond to different stimuli.
(B) Primates from different regions tend to show more variation in behavior than do primates from the same geographical area.
(C) Primate behavior is extremely complex and thus difficult to fully understand.
(D) Many scientists who study modern-day primates are not concerned with the behavior of extinct primate groups.
(E) Even those modern-day primate groups that have not been affected by habitat loss are still thought to be quite different from extinct primate groups.

(A) This choice suggests that studying the response of a primate group to any external factors can help scientists predict how other primates would respond to different stimuli. If this is true, it undermines the argument that studying modern primates is questionable due to their exposure to different external stimuli.
(B) While acknowledging the complexity of primate behavior, this choice does not directly address the concern about the impact of habitat loss on modern primates.
(C) This choice is identical to (B) and does not provide additional information.
(D) This choice focuses on the interests of scientists but does not address the validity of using modern primates to study extinct ancestors.
(E) This choice emphasizes the differences between modern primates and extinct ones, supporting the argument that studying modern primates may not accurately reflect the behavior of extinct ancestors.

Argument says studying modern primates to understand extinct ones is questionable because modern ones live under different external conditions (like deforestation).
We need a statement that weakens this — i.e., shows that even if external conditions differ, studying modern primates can still help understand extinct ones.
(A) says studying how primates respond to *any* external factors helps predict how others respond to *different* stimuli.
→ This means even if modern primates live under different conditions, their responses still give useful insights.
→ So the method is still valid.
→ This **weakens** the argument.
Answer: (A) — sufficient reason: it shows the research can still be valid despite different external conditions.
