In many scientific disciplines, scientists generally do not do highly creative work beyond the age of forty, a tendency that has normally been taken to show that aging carries with it a loss of creative capacity. However, by the age of forty most scientists have been working in their chosen field for at least fifteen years, so an alternative explanation is that spending too long in a single field reduces the opportunity for creative thought.
Investigating which of the following would be most useful in choosing between the competing explanations described above?
A. Whether among those scientists who do highly creative work beyond age forty a large proportion entered their field at a considerably later age than is common
B. Whether scientists' choice of research projects tends to be influenced by their own belief that their most creative 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, such as teaching and mentoring, than they do in pursuing their own research
D. Whether funding agencies are more inclined to award research grants to scientists who are veterans in their field than to scientists who are relative newcomers
E. Whether there is significant variation among scientific fields in the average age at which scientists working in those fields are at their most productive
A
这道题怎么理解呢？问的是削弱啊？还是加强啊？还是support呢？

这里的E为什么不对呢？
求求好心人帮忙，实在是困扰我太久，过几天就考试了，还不幸有裸奔的可能，看在我这么点背的份上帮帮我吧，81题如果都是说前提不成立导致结论错的话E也应该对呀~~~E与A什么区别呢？
评价题。其实也就是加强。
选A。
A 说明 换了领域，科学家反而很能创新，说明不是 age 造成的创造力下降，而是太久了机会已经没了。
很好的评价/加强了文中的观点。
不要用XDF 的东西去思考。。
