求助OG13的65题

bazhiqiong

麻烦想请教下大家，OG13的65题C和D选项
Digging in sediments in northern China, evidence has been gathered by scientists suggesting that complex life-formsemerged much earlier than they had previously thought.
(C) scientists have gathered evidence suggesting that complex life-forms emerged much earlier than
(D) scientists have gathered evidence that suggests a much earlier emergence of complex life-forms than that which was

问题：1. C中previously thought省略了什么？为什么能省？
2. C中suggesting我理解是现在分词做定语不加逗号的情况下一定会就近修饰，过去分词不管加不加逗号都就近修饰，对吗？
3. D中我刚开始理解的是suggest限制性定语从句修饰evidence，than后的that指代emergence，不知道有什么问题？

本人语法较菜，希望大家多多帮忙，多谢多谢

多谢啦，但是可能没太理解您的回复，因为这道题其实应该选C的，就是suggesting直接修饰evidence啊

感谢感谢，就是有一点还是不太明白，这个suggest为什么不能接名词啊？

1. C 中省略了动词。 life-forms emerged much earlier than (they were) previously thought ( to have emerged).
3 that 是指代emergence, 但是这里不符合逻辑， 因为  a much earlier emergence.... than (the emergence) which was previously thought, 读起来是好像有2个emergence,以前被认为的emergence 和现在被证明的。 我也刚接触SC，也不确定这样理解对不对。

好久不搞GMAT生疏的不行。
正常的英文语境，如果用evidence that...是描述这个evidence suggests bla bla bla。如果用suggesting，则是描述scientists have gathered evidence这个动作，首先这不符合文章要表达的意思。并且如果非要这么用，evidence和suggesting中间一般要有逗号

1. scientists have gathered evidence suggesting that complex life-forms emerged much earlier than (life-forms that has been) previously thought. 比较的是主语，但是没有宾语，所以可以去掉名词和助动词。省略在于不影响歧义尽量简约，你在SC专区里找找有人发的RON关于省略的讲解看看吧。

2. 是的，名词修饰语都是就近修饰。

3. which不能指代that。was时态不对。 suggest不能直接名词。
