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答案是B,可是我怎么想都是削弱的啊，我选了C，大家帮帮忙啊~~~~感激不尽~~

题目意思是大多科学发明在40岁之前，但是有一种解释是：这个不是因为40人老了，而是往往科学家到40岁时已经研究了15年甚至更多，江郎才尽了。换句话说，是不是江郎才尽和几岁没关系，而是和你研究了几年有关系。B选项就说，很多在40岁以后有成就的人，他们进入这个圈子普遍较晚，也就是说他们基本也是在15年这段时间里发明的，只不过起步较晚~~~你70岁当科学家，弄不好80岁也能发明，反过来，你10岁开始研究，到25岁基本就不可能研究出什么东西来了~~~

呃，理解了，LS好人好报~~谢谢啊~~~
