D的assist短语搭配错误吧...而且those of others...逻辑错误

as‧sist

1
[intransitive and transitive] to help someone to do something
assist (somebody) with/in something
You will be employed to assist in the development of new equipment.
see usage note help 1
2
[transitive] to make it easier for someone to do something
They had no maps to assist them.

谢谢，但是补充assist用法：习惯用语

	assist sb. with sth.
	帮助某人[做某事]
	assist sb. to do sth.
	帮助某人[做某事]
	assist sb. in doing sth.
	帮助某人[做某事]

例句：Computer Program can assist to detect Heart Attack.

不明白those of others有什么错，我觉得这样对啊

"assist sth. in doing " is the key point in this sentence

搞懂了，先说那个"those of",没错， those 指代specis, distinguish their own species from species of others.
再说assist,to do 和in doing 都没错，但要句子的逻辑意思，“taste the hydrocarbons on prospective mates”作fly定语的，所以D会给人造成误解为assist fly to taste(do)...to distinguish(目的状语)...，好吧，退一步讲，to do 可以做定语，但也没that好。

这道题用了我很长时间才琢磨出来，真不知道上面的那些大牛是不是第一遍就做对了，还是错了以后还想明白的，真是服了YOU.

有疑问 E中的 distinguishing their own species from others不错吗

不是应该用 from those of others更好吗

为什么前面认为 from those of other 有问题

请指点啊

只有 assist sb in doing/ with sth，没有 assist sb to do
!! Do not say 'assist someone to do something'. Say assist someone with something or assist someone in doing something.---------- from LDOCEonline http://www.ldoceonline.com/dictionary/assist_1
5 楼解释很清楚，those 只能指代 species，但是代入之后出现逻辑错误，所以选 others

those of others双重了。就好像不说those of Zhao Wei's ，而说those of Zhao Wei一样。

D 中those of 无合适指代
