Government representative: Between 1996 and 2005, the gray wolf population in Minnesota grew nearly 50 percent; the gray wolf population in Montana increased by only 13 percent during the same period. Clearly, the Minnesota gray wolf population is more likely to survive and thrive long term.
Environmentalist: But the gray wolf population in Montana is nearly 8 times the population in Minnesota; above a certain critical breeding number, the population is stable and does not require growth in order to survive.
The environmentalist challenges the government representative's argument by doing which of the following?
(A) introducing additional evidence that undermines an assumption made by the representative
(B) challenging the representative's definition of a critical breeding number
(C) demonstrating that the critical breeding number of the two wolf populations differs significantly
(D) implying that the two populations of wolves could be combined in order to preserve the species
(E) suggesting that the Montana wolf population grew at a faster rate than stated in the representative's argument
OFFICIAL EXPLANATION
(A) introducing additional evidence that undermines an assumption made by the representative
This is the correct answer.(B) challenging the representative’s definition of a critical breeding number
This is a Mix-Up answer. The environmentalist discusses critical breeding number, not the representative.
(C) demonstrating that the critical breeding number of the two wolf populations differs significantly
This doesn't f i t into one o f the standard trap categories. The environmentalist does mention the term “critical breeding number" but does not say that this number differs significantly. Rather, the environmentalist says that the population size differs.
(D) implying that the two populations of wolves could be combined in order to preserve the species
This is a Real World Distraction answer. It might be an interesting strategy in the real world\ but the argument doesn't mention it.
(E) suggesting that the Montana wolf population grew at a faster rate than stated in the representative’s argument
This is a Mix-Up answer. The environmentalist does mention a number, but that number does not represent a rate o f growth.
