寂寞的自由

Suitable habitats for gray wolves have greatly dimin-
ished in area. In spite of this fact, the most sensible
course would be to refrain from reestablishing gray
wolves in places where previously they have been hunted
out of existence. Striving to bring back these animals to
places where they will only face lethal human hostility is
immoral.

3. The argument above depends on
(A) an appeal to an authority
(B) a belief that gray wolves are dangerous to human beings and livestock
(C) an assumption that two events that occur together must be causally connected
(D) an assumption that the future will be like the past
(E) a threat of violence against those persons presenting the opposing view

这个题如何考虑呢？谢谢大家

关键是"previously", 这里隐藏的假设是: 以前那里的人也是敌视他们的. 因此,D正确.
