A conservation group is trying to convince Americans that the return of gray wolves to the northern United States is a positive development. Introduction of the wolf faces significant opposition because of the wolf’s reputation as a killer of people and livestock. So that the wolf will be more acceptable to average Americans, the conservation group wants to dispel the myth that the wolf is a vicious killer.

Which of the following, if true, would most weaken the opposition’s claim?

(A) Wolves are necessary for a healthy population of white-tailed deer because wolves kill the weaker animals and limit the population to sustainable numbers.
(B) In a confrontation, black bears are much more dangerous to humans than wolves are.
(C) Wolves are superb hunters, operating in packs to track down their prey and kill it.
(D) There has never been a documented case of a wolf killing a human in the 500-year recorded history of North America.
(E) Wolves occasionally take livestock because domestic animals are not equipped to protect themselves the way wild animals are.

No. The question concludes wolf is a killer of people and livestock. Since we are to weaken this conclusion, we would be looking towards an option that tell us that Wolf does not kill humans and livestock / not dangerous.
But note that in option E, it says wolf kills livestock, which is a direct strengther (not what we want).

While i get why D could be the answer (considering it provides statistical evidence) I am not entirely convinced. Since the stem states that the "conservation group is trying to convince Americans that the return of gray wolves to the northern United States is a positive development" isn't it possible that the wolves could have been responsible for killings prior to the "500 period" and the lack of documented killing is due to their absence.

Can anyone please clarify this ?

Hi Tan2017,

Here is the official explanation.

This critical reasoning question asks you to weaken the opposition’s statement that the wolf is vicious, so look for a statement that shows that the wolf isn’t a danger to people or livestock. Begin by eliminating answers that don’t address the appropriate conclusion. Choice A deals with the beneficial impact of wolves on the ecosystem but doesn’t talk about their propensity toward viciousness, so eliminate it. You can also eliminate C, because the hunting prowess of the wolf isn’t the issue, and this choice may actually strengthen the contention that wolves are dangerous. Choice E also doesn’t weaken the conclusion in question; it seems to argue that wolves may threaten livestock. This leaves you with B and D. Choice B compares the danger posed by wolves with the danger posed by black bears. Even if a wolf is less dangerous than a bear, that doesn’t mean a wolf isn’t dangerous. The best answer is D, because it provides a statistic that weakens the opposition’s argument that wolves are dangerous to humans. Correct answer: D.

Hope this helps. All the best.
