1. I agree that the answer is D. but I cannot help you find the choice E.
8. 1)if choice A is changed as the following, this choice would be the best choice: .......  Since the birds were responding to some factor that also influenced the events, therefore the events themselves probably match the predictions.
   2) I think the difference between choice B and the origin question is the difference between likely and must. I cannot find other differece between B and the origin.
   3) if choice D is changed as the following, this chioce would be the best: Since specific substances in vegetables are known to help the body flight disease, vegetables should be part of factors that led people to have longlife.

14. the flaw of the origion question is : event a = event b, although all circumstance would be changed.( sorry, I do not remember the name of this fallacy)

18、D。E中的信息题目已经给了。
1、C比较好。
8、E中表达的意思就是题干的最后一句话。
25、C没有表达出比例值。就算是这个人毕业了，另外还有其他人毕业，比例值都可以小于5%。而E的比例换算与原题干是完全一样的。
COOK：其实这些逻辑错误的相似性的题目，在GMAT中是不考的。
