39. GWD17-Q39:

Which of the following most logically completes the passage?

 

On the whole, scientists do their most creative work before age forty, a tendency that has been taken to show that aging carries with it a loss of creative capacity.  An alternative explanation is that by age forty most scientists have worked in their field for fifteen or more years and that by then they have exhausted the opportunity for creative work in that field.  Supporting this explanation is the finding that ______.

 

A.      the average age of recipients of scientific research grants is significantly greater than forty

B.       a disproportionately large number of the scientists who produce highly creative work beyond age forty entered their field at an older age than is common

C.      many scientists temper their own expectations of what they can achieve in their research work by their belief that their creativity will decline as they age

D.      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

E.       there is a similar diminution of creativity with age in nonscientific fields, such as poetry and musical composition

 为什么C不对呢？

C不是就是暗示说40过后就没有创造性了么？

我选D，不知对不对。。。

选B。produce highly creative work beyond age forty 是那些后进入该领域的人（暗指他们在该领域工作时间相对common短），也正因时间短，他们才有创造力。这与题目中An alternative explanation相吻合，因为most scientists have worked in their field for fifteen or more years，即工作时间长造成了没有创造力。 不知道说清楚没有。

关键出在alternative这个词上，这里带有转折的意思

我也选B

C是诉诸权威了....（典型错误选项） 不具有说服力

D正好表明了 工作时间短——creative 与原文一致
