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

这题可以看成是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。的加强题

原文的意思其实是，15年后，科学家失了创造性工作的机会，所以科学家在40岁前做创造性工作

B的话，说那些在40岁之后做创造性工作的的年纪比普通的大，也就是说创造性工作跟几岁工作没事，只跟工作的长度（15年），有关
