(E) to attract females rises and falls in accordance with the surrounding temperature, in fact possibly serving

蓝色的是答案。。请问句子中的they和it为什么不存在代词指代不清的问题。
比如95题 they的前面有两个复数名词 frogs that metamorphose...... 和mountain yellow-legged frogs...为啥they 没有指代歧义
96题，it的前面有两个单数名词 the number of chirps...和 temprature...
请教NN们代词指代啥时候就近指代，啥时候优先指代句子主语呢？ 感谢ing

wwc008love，看到你得帖子，你应该也是有跟进RON的SC知识点的。那么你应该有看到过RON有在很多帖子里不断地重复说过GMAT对代词的ambiguous有时是非常的tolerant的！RON通常用来举例的题目就是Prep07/section1/NO.1那道fish。其实就是异常的ambigous，可是人家GMAT说他对就是对了

如果要从代词是否“指代不清入手”经常性的会掉入排题的误区，觉得这个是“ambiguous”的，排了，结果却对了。所以最好排题思路的前几个split不要用代词指代来判别。不牢靠。

这两道题，第一道就是用Unlike的解题思路和take some time to do sth的idiom，不存在until用法，还有第二道是不可以用独主做adv modifer，所以才选你认为ambiguous的选项的

但是代词有时排题的时候非常有用，在句子里可以做hint的作用，告诉你这个句子是单数还是复数，让你在划线句中选取主谓一致的hint.

排题一开始的前两个split,（反正不是最后一个split点)别用那种“时对时错”的知识点去排，比如这个“代词”的用法。要用绝对，一定，出现必错的知识点去排，比如“主谓一致，平行，比较等等”
