A conservation group is trying to convince Americans

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.
