OE for reference:
Overview:The argument in the letter objects to a criticism presented in a newspaper article. The article reportedly asserted that a claim made by environmentalists that more wolves on Vancouver Island are killed by hunters than are born each year was disproven by studies indicating that the total number of wolves has remained roughly constant for 20 years. The argument in the letter counters this assertion of disproof by presenting additional evidence: environmentalists have been introducing new wolves onto Vancouver Island for 20 years. This means that it is possible that hunters do kill more wolves than are born each year, while the additional wolves introduced by environmentalists have been keeping the population constant.
Your task is to identify the conclusion of the argument, which is the claim that all of the other parts of the argument are intended to support.
The Correct Answer:E As outlined in the "Overview," the letter is directed toward raising a specific objection to a newspaper article and presenting evidence to support that objection. The claim in (E) basically restates that objection, which means that it is the conclusion of the argument given in the letter.
The Incorrect Answer Choices:A The argument does claim that environmentalists have been introducing new wolves into the Vancouver Island wolf population, and the argument accepts the article's assertion that the wolf population has remained roughly constant. Together these two claims could be a basis for concluding what (A) states, but the argument never explicitly states the view in (A). Instead, the argument is set up to support a different claim, which is stated in (E). So (A) is not the conclusion of the argument.
B The argument does not directly address any claim about the number of wolves killed by hunters relative to the number born each year. It merely argues that the article has not disproven the claim that more wolves are killed by hunters than are born each year.
C (C) is a claim about what should be done. But the argument presents factual claims about what is actually happening to the wolf population and uses these to evaluate the article and the argument that it makes—it doesn't say anything about what should be done regarding the wolves on Vancouver Island. So (C) is not the conclusion of the argument.
D The argument criticizes the conclusion that the article draws from studies indicating that the total number of wolves on Vancouver Island has remained roughly constant. The argument does not, however, dispute the accuracy of those studies. So (D) does not express any claim made by the argument, which means that it could not possibly express the conclusion.
