Almost like clones in their similarity to one another, the cheetah species’ homogeneity makes them especially vulnerable to disease.

A.      the cheetah species’ homogeneity makes them especially vulnerable to disease

B.     the cheetah species is especially vulnerable to disease because of its homogeneity

C.     the homogeneity of the cheetah species makes it especially vulnerable to disease

D.     homogeneity makes members of the cheetah species especially vulnerable to disease

E.     members of the cheetah species are especially vulnerable to disease because of their homogeneity

E the best

請問一 下b為什麼不對啊    3q

spices 不是有種類的意思嘛(單數)

The giant panda has become an endangered species.

上次我确实说错了，而且是个严重的错误。再尝试一下，

B的逻辑不如E好，因为是相似性，不能说一个品种的相似性

只能说每个个体的相似性，就拿its homogeneity说，只有一个对象，没有比较对象，怎么会有共同点呢？

不知道这样LZ觉得行不？
