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
支持这个说法也就是人过了40岁确实就是创新能力的下降啊，为什么答案是B。。。请大家看一下

一般来说，科学家在他们四十岁之前做最具创造性的工作，随着年龄的增加他们的创造力会流失。而另一种解释是说这些四十岁左右的科学家在他们的工作领域工作了15年或者更多，所以他们耗尽了很多这种机会。问支持第二种解释的说法是
背景——科学家的创造力会流失
解释一   年龄增长
解释二   在同一工作领域时间长    （需要支持的说法）

B选项说  很大一部分超过四十岁且很有创造力的科学家进入他们的领域要比一般的科学家晚，也就是说他们比一般科学家在同一领域工作的时间短，等于是题目的逆否命题

牛牛的方法我懂，支持第二种解释：因为在一个领域太久了失去了发展机会---导致40岁后的科学家没啥成果，可是逆否后，原因我是明白了，可是结果是科学家才进入领域不久，这个和机会有啥关系吗？不好意思，还是迷迷糊糊的。。。

要支持的二个失去创造力的原因----在一个领域工作太长，就要排除第一个原因-----年龄增长导致creativity的下降对结论的影响，所以B中，有很多超出了40岁的人，仍然有很高的creativity，是因为他们进入该领域晚，即在某领域的时间不长，并拥有创造力，但是他们确是40多岁这种在第一种原因看来已经没有创造力了的人。所以支持第二个原因
