怎么判断species是单数还是复数

species和fish都是单复数相同的，怎么判断用代词是应该用单数还是复数？

比如：

150.(32705-!-item-!-188;#058&007266)

Hydrocarbons, with which fruit flies perfume themselves in species-specific blends, are known to be important in courtship, and apparently this assists flies that taste the hydrocarbons on prospective mates to distinguish their own species from that of others.

E

(A) and apparently this assists flies that taste the hydrocarbons on prospective mates to distinguish their own species from that of

(B) and apparently this assists flies when they taste the hydrocarbons on prospective mates in distinguishing their own species from those of

(C) which apparently assists flies that taste the hydrocarbons on prospective mates in being able to distinguish their own species from

(D) apparently assisting flies to taste the hydrocarbons on prospective mates to distinguish their own species from those of

(E) apparently assisting flies that taste the hydrocarbons on prospective mates in distinguishing their own species from
这里是不需要that/those指代的，我主要是想知道如果需要的话，是that还是those

看到这个问题，楼主可能已经考好了吧！大家在讨论下咯

their own species 这里的species我认为是单数，因为own的种类不可能占据几种的，own只能是一个种类！

这里不需要用that，如果用了翻译过来就是区分自己的物种和其他物种的物种

their own speices，their 应该是指的files吧？，their own species 应该比的是species啊，我觉得不加those of 不是会造成他们自己的物种和他们自己的others（别的物种）的歧义吗？我怎么觉得用their own species 和those of others比较清晰呢？
