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 fields 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 scientists who produce highly creative work beyond age forty entered their fields 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 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.

参考答案选B，为什么呢？谁来拆拆题呀

An alternative explanation is that by age forty most scientists have worked in their fields for fifteen or more years and that by then they have exhausted the opportunity for creative work in that field.

这句话的意思是说，到40岁的时候，科学家们已经在他们的领域工作了40年甚至更长的时间，那时他们已经没有什么机会在那个领域里从事创造性的工作。

这个解释强调了由于工作的时间长才丧失了创造性。从另外一个角度说，如果参加工作晚，工龄短，那么创造性丧失的也晚。所以b符合解释。

是B

首先，应该清楚，this explanation在此指代解释2。

其次，B说，大量的不成比例的产生创造性成果的超过40岁的科学家进入他们的领域比一般人晚。刚好证明了解释2而否定或部分否定了解释1。
