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 ______.

1. the average age of recipients of scientific research grants is significantly greater than forty
2. 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
3. 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
4. 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
5. there is a similar diminution of creativity with age in nonscientific fields, such as poetry and musical composition

1、提炼结论说，因为用光了所有的机会，所以无法创新工作；

2、无关词排除法：

A，在反对结论；

B，说40岁以后进入这个领域的科学家如何如何，无关内容；

C，科学家祈望自己如何如何，也是无关内容；

D，有关内容；

E，说到非自然科学领域，也是无关内容。

最后一句的this explaination是指哪个？

还是不太能理解为什么C是无关。

1、this explanation 就是对应那个alternative explaination；

2、C说科学家认为他们的创新能力下降了，文章说他们用尽了所有的机会，文章中没有提到能力的变化；
