求教GWD3-20，最烦BF题了。。

Scientists typically do their most creative work before the age of forty.It is commonly thought that this happens because aging by itself brings about a loss of creative capacity.However, studies show that a disproportionately large number of the scientists who produce highly creative work beyond the age of forty entered their field at an older age than is usual.Since by the age of forty the large majority of scientists have been working in their field for at least fifteen years, the studies’ finding strongly suggests that the real reason why scientists over forty rarely produce highly creative work is not that they have simply aged but rather that they generally have spent too long in a given field.

In the argument given, the two portions in boldface play which of the following roles?

A.The first is the position that the argument as a whole opposes; the second is an objection that has been raised against a position defended in the argument.

B.The first is a claim that has been advanced in support of a position that the argument opposes; the second is a finding that has been used in support of that position.

C.The first is an explanation that the argument challenges; the second is a finding that has been used in support of that explanation.

D.The first is an explanation that the argument challenges; the second is a finding on which that challenge is based.

E.The first is an explanation that the argument defends; the second is a finding that has been used to challenge that explanation.

为什么答案是D呢？我觉得是E咧。。
这个题目conclusion就是最后一句：that the real reason why scientists over forty rarely produce highly creative work is not that they have simply aged but rather that they generally have spent too long in a given field.对么？
然后第一个BF是反对，第二个是支持的，两个BF之间呈反对
我的理解对么？

对的 结论就是这个。但defend这个词有着support的意思呀。。所以E必然不对。第一个BF的观点文章显然是反对的

第一个的BF 是文章所不同意的一个老观点：有AGE引起创造力的损失。
第二个BF是解释新观点。

要读懂argument是什么，即最后一句话the real reason why scientists over forty rarely produce highly creative work is not that they have simply aged but rather that they generally have spent too long in a given field.
带着结论回到第一个黑体，显然衰老降低创造力是结论要质疑的。再带到第二个黑体，是一个事实即很多产出高创造力作品的人都在40以上。可以看出这是质疑第一个黑体的基础。
