C

对于这道题 我不太明白：

1。 在这个句子里面加上And在结构上有什么必要。我是说，是必需的呢？还是可有可无的呢？

- since [A ....feet] is a part of whole clause which must be separated by "and" from another whole cluase. 

2。 加上and it is就不会有修饰成分不明确的毛病了？（很多人讲a不对是因为修饰不明确）

- I think those who think A is answer made an misunstood about the subject of the first clause.The subject of first clause in the Quetzalcoatlus not A huge flying reptile .If you think A huge flying reptile is the subject you will get into trap placed by ETS.

3。 能用and就不能用which? 我的语法很坏。。。。。。

- which could be used in Gmat to introduce an infinitive attributive clause.And is used to combine two clauses ,both have whole structure grammatically.

诚心求教，我就是看着这个and 很是不顺眼的说。
