偶也选E~
老外的解释：

Question 1:

The correct answer must be choice A.

If we have two trees that are from the same area, then of course the climate would have been the same in any given year. (It would be bizarre if we had significantly different climates at the same time in the same place).

So, for two trees from the same area, the rings corresponding to overlapping years would, according to the passage, undoubtedly exhibit similar patterns.

For choice B, note that the passage never asserts that legions of trees are necessary to arrive at conclusions about past climatic conditions. If we have only one tree, of course it is less convincing than if we have many (as always, a larger sample size provides a more solid foundation for arriving at confident conclusions). However, based on the explanation in the passage, there is no reason to think that an expert would require multiple trees to read off past climate conditions; the method described did not in any way depend on some sort of comparison of tree rings in multiple trees.

(Govi, choice D is wrong--the rings may be complacent if the two trees are in an area with a lot of groundwater).

看了老外的解释，偶觉得E不对的原因应该是wet or dry condition对于研究都不好吧。

PS:我做的时候一直对complacent是什么意思feel confused..

文中有：
these "complacent" rings tell nothing about changes in
climate.


不知道complacent具体神马伊斯，字典上是自鸣得意，=〉自己以为可以得的意思，把树拟人化了？。。反正是贬义的。。
