Conservationist: The population of a certain wildflower is so small that the species is headed for extinction. However, this wildflower can cross-pollinate with a closely related domesticated daisy, producing viable seeds. Such cross-pollination could result in a significant population of wildflower-daisy hybrids. The daisy should therefore be introduced into the wildflower’s range, since although the hybrid would differ markedly from the wildflower, hybridization is the only means of preventing total loss of the wildflower in its range.

34. Which one of the following is an assumption on which the conservationist’s reasoning depends?

A. The wildflower currently reproduces only by forming seeds.

B. The domesticated daisy was bred from wild plants that once grew in the wildflower’s range.

C. Increasing the population of the wildflower will also expand its range.

D. Wildflower-daisy hybrids will be able to reproduce.

E. The domesticated daisy will cross-pollinate with any daisy like plant.

我是选D.

hybridization is the only means of preventing total loss of the wildflower in its range

这是结论，ASSUME支持结论，取非削弱，

D. Wildflower-daisy hybrids will be able to reproduce. 取非, 这样CROSS -POLLINATION产生的HYBIRDS 不能够繁殖,那这WILDFLOWER还不是要灭绝，削弱。

其他的似乎不对。

这题目感觉就象OG里的一些题目，说一种方法被用来区分A和B拉，假设的话，就是这样的一种方法是存在的，或者说是可行的。
