一个比较矛盾的SC知识点过两天要上考场了求助

有一个知识点是 to是用来修饰主语的，
这个知识点记得比较牢因为有一道题做错了

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.

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
选E不选D是因为D用了to，Hydrocarbons是不能去taste一个东西的

但是在这道题里
Nineteenth-century doctors thought that alcohol, when ingested, passed through the stomach into the bloodstream and was broken down only by the liver; recent studies, however, have led them to conclude that the stomach breaks down up to 20 percent of ingested alcohol before it reaches the liver.

C have led doctors to conclude
E lead to the doctors` conclusion

答案是C
因为to是修饰主语的，所以这里的to conclude是去修饰recent studies，
但是recent studies能去conclude一个结论吗，不应该是doctors去conclude一个结论吗？
所以我就选了个比较丑的E

求解答
感觉有一些矛盾，不知道怎么说服自己

谢谢大家的帮助，可能是做题有些太拘泥于一个点不放了，我有找到另一道题是关于to修饰主语这个问题的
New genetic evidence-together with recent studies of elephants' skeletons, tusks, and other anatomical features-provide compelling support for classifying Africa's forest elephants and its savanna elephants as separate species.
A provide compelling support for classifying
B provide compelling support for the classification of
C provides compelling support to the classification of
D provides compelling support for classifying
E provides compelling support to classify这道题答案是D 因为evidence是不能去classify一个东西的所以E错
因为这道题DE的split只有for和to，所以用to修饰主语很容易能解决
所以就很不解，为什么一个规则到了另一题上，就完全不同

我觉得你的思路有点跑偏… 第一题我觉得D错的更在于distinguish their species from those of others. others已经是species了，所以这个those没有指代，所以错。
第二题里面，lead someone to do something 是一个idiom，指的是引导xxx去做一件事情，跟lead前面的主语没有关系。

至于第一题里面的to，更多的是表达了一个objective，会产生歧义，让人觉得xxx assist flies是为了taste xxxx

嗯嗯明白了非常感谢
但是还有一个疑惑的点就是
比如A write a book to emphasize sth里的to应该是表目的，A为了emphasize sth去write a book
但是A lead sb to do sth 并不是 A为了to do sth去lead sb
怎么分辨这两种形式
可能是我做sc太格式化了

Above two examples you should focus more on idiom:
In the first question, split between D and E is "assist in doing" H blablabla, assisting flies in distinguishing their own species from others. (there are also other defects in E - "those of" no antecedent )
In the second question, studies have led doctors to conclude, idiom "lead to". lead doctors to conclude.

What you may ask here is the function of infinitive verb "to do" , which is another broad topic..

我也经历过你的阶段。。。根据我的经验如果你遇到了一道不符合你总结规则的题目，多半那个规则是错的

第一题是俗语呀 assist sb in doing 第二个是lead sb to do

第二题e的the doctors’指的是十九世纪的医生。

You are trying to discuss rules that doesn’t even exist.
