Environmentalist: It is true that the tiny population of grey wolves
in the southern part of the country have much in common with the
larger population in the north. Based on these similarities,
government o¢ cials are claiming that the distinct population in the
south is not endangered. The claim is mistaken. The wolf
population in the south has no contact, and is incapable of
breeding with the population in the north, so it should be
considered a distinct species, and thus an endangered one.
Which of the following, if true, provides the strongest support for
the environmentalistÂ’s claim?
(A) Historical data suggests that the wolf population in the
south descends from a separate population that lived
in the north less than a century ago.
(B) The two wolf populations have genetic di¤erences that
are more substantial than the di¤erences that cause
two populations of red wolves to be categorized as
distinct species.
(C) There are currently no wolf species categorized by the
government as endangered.
(D) The environmentalist previously worked for the
government in a capacity that allowed him to help
classify certain species as endangered.
(E) There are large numbers of grey wolves in captivity
throughout the country.
