E选项是说，母鼠的母性行为会被小鼠散发的气味抑制，符合题干说的当移除嗅觉或小鼠气味腺体时，母鼠会更快地展现母性行为

除去毕老师的不定式和从句区别，E选项的最好排除应该是 Ron: the worst thing about this choice, though, is "that". you cannot EVER use "that" to refer to people, even though we do so all the time in spoken english.

(E) 雌鼠对非亲生幼鼠产生的母性被幼鼠的气味阻止了。所以 by removing the scent-producing glands of the pup，就可以缩短female rats表现母性行为的时间

More than 300 rivers drain into Siberia's Lake Baikal, which holds 20 percent of the world's fresh water, more than all the North American Great Lakes combined.
more than all the North American Great lakes combined 修饰整个which引导的从句内容

更正1-比较结构是成对儿出现的，less +than，没有less ...compared这种说法，因此i排除ABD；
2-E和后面的题干分别是两个独立的句子，之间需要连词，nevertheless是副词，不能够链接两个句子，错误１；另外E中比较的是在不同的地点，其实发生的时间上也有比较，未体现出来，错误２；排除E；
综上，选C
