80. In many scientific disciplines,scientists generally do not do highly creative work beyond the age of forty, atendency that has normally been taken to show that agingcarries with it a loss of creative capacity. However, by the age offorty most scientists have been working in their chosen field for at leastfifteen years, so an alternative explanation is that spendingtoo long in a single field reduces the opportunity for creative thought. Investigating which ofthe following would be most useful in choosing between the competingexplanations described above? (A) Whether among those scientists who do highly creative work beyondage forty a large proportion entered their field at a considerably later agethan is common (B) Whether scientists' choice of research projects tends to be influenced by their own belief that their mostcreative work will be done relatively early in their career (C) Whether scientists who are older than forty tend to find more satisfaction in other activities, suchas teaching and mentoring, than they do in pursuing their own research (D) Whether funding agencies are more inclined to award research grantsto scientists who are veterans in their field than to scientists who arerelative newcomers (E) Whether there is significant variation among scientific fields inthe average age at which scientists working in those fields are at their mostproductive
附上自己的理解和疑问 à 梳理原文给的信息：对scientists generally do not do highly creative work beyond theage of forty 给出了两种解释：* 年龄太大 导致创作力下降 * 工作年限太久 导致创作力下降 Q: 到底是哪种原因？ à 必须能够支持其中一种，削弱另外一种。不可以同时削弱或者同时支持。（CORRECT ???)
因此问题的回答势必可以得出：1是因为年龄太大，不是因为工作太久 2不是因为年龄太大，是因为工作太久
我的疑问主要是对A & D [size=13.3333px]（可以理解BC作为第三个因素出现，同时削弱了两种因素）
A. 回答YES, 说明不是年龄太大的问题，是因为工作太久 ---可以 回答NO，能说明什么呢？这些科学家既是年龄大，又是工作时间久，
D. 回答YES, 应该是鼓励了老手科学家，那么尽管如此，他们还是在40岁以后创作性下降了，那到底是因为年龄太大还是工作时间太久，不知道 ----没有加强或否定 其中一种或两种 （ [size=13.3333px] [size=13.3333px]CORRECT???) [size=13.3333px]
回答NO, 说明并没有给老手科学家更多的鼓励（那么鼓励可能更少，或者一样多）。 如果鼓励更少，可能是第三因素，可以去解释为什么40岁以后的科学家创造性下降。 如果鼓励一样多，那和回答YES一样不知道到底是哪个因素导致的。 （ CORRECT???)
这道题我看了很多帖子的解释，包括RON的，都没能解释我的疑问。。。。
寄希望于CD上的大神
提前感谢了！
