In many scientific disciplines, scientists generally do not do highly creative work beyond the age of forty, a tendency that has normally been taken to show that aging carries with it a loss of creative capacity. However, by the age of forty most scientists have been working in their chosen field for at least fifteen years, so an alternative explanation is that spending too long in a single field reduces the opportunity for creative thought.

Investigating which of the following would be most useful in choosing between the competing explanations described above?

正确答案: A

In many scientific disciplines, scientists generally do not do highly creative work beyond the age of forty, a tendency that has normally been taken to show that aging carries with it a loss of creative capacity.  However, by the age of forty most scientists have been working in their chosen field for at least fifteen years, so an alternative explanation is that spending too long in a single field reduces the opportunity for creative thought.

Investigating which of the following would be most useful in choosing between the competing explanations described above?

A. Whether among those scientists who do highly creative work beyond age forty a large proportion entered their field at a considerably later age than is common

B. Whether scientists' choice of research projects tends to be influenced by their own belief that their most creative work will be done relatively early in their career

C. Whether 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

D. Whether funding agencies are more inclined to award research grants to scientists who are veterans in their field than to scientists who are relative newcomers

E. Whether there is significant variation among scientific fields in the average age at which scientists working in those fields are at their most productive

为什么选c 解释不太看得懂

错了,答案是A,题目上给的解释是这样的:
说科学家过了40岁创造力就下降了。但是大多数过了40岁的科学家在自己的领域至少工作了15年了,所以这种单一的模式减少了创新思维的产生,问评价?A选项在说是否那些过了40岁但是高创新的科学家进入该领域晚,言下之意,是的话,那就说明文章的假设是对的,因为进入晚的还没到15年,所以还没失去创造力。如果假设是错的,那么说题干就是错误的,即便过了40岁但是还是创造力高,跟年龄没关系。
又看了一遍,还是不太明白

答案就是一方面不能解释而另一方面能解释的。
一方面:年龄大于40,不容易做出成就。
另一方面:进入领域太久,不容易做出成就。
A答案:年龄大于40还能有成就,这个第一个方面解释不了,但是后半句是转入新领域不久。所以另一个方面就解释了。

我觉得还是不对
A是说那些40岁以上有成就的人是不是大部分都被认为进入该领域晚。

如果是进入该领域晚,40岁以上有成就的,说明不是年龄大于40,不容易做出成就,而是进入领域太久,不容易做出成就。

如果是进入该领域不晚,40岁以上有成就的,说明既不是进入领域久,不容易做出成就,也不是年龄大于40,不容易做出成就。

我认为,题目中
conclusion:40岁以上的scientists没有什么creative work
两种explanations:1、年龄增长降低creative capacity
                          2、在single field干太久降低 creative capacity
问:哪个option可以很好的衡量出到底是选ex1 还是ex2

A说,看那些40岁以上有creative work的scientists是不是大部分都比其他scientists进入那个领域要晚。

A把 ex1中的年龄 和ex2中的 field 结合在一起,即只要回答这个问题,就知道哪个ex better了、

题干是两个Option  1:年纪因素; 2:从事时长因素
A是问:超过40岁仍然做出创意性工作的人是不是入行比大多数人要晚很多?
回答是:是--〉入行很晚-〉从事时长较短--〉2这个因素有影响
             否--〉入行早----〉从事时间较长--〉2这个因素没有影响
A这个答案至少可以确定2的决定作用,但是其他选项都两个因素间的选择没有影响,所以A选项最优。

这是我的想法

求NN

对于答案A:如果回答YES, 说明大部分到了40岁仍有创造力的人工作年数还不够长, 所以是工作时间制约创造力。
如果回答NO, 说明大部分到了40岁仍有创造力的人并没有晚进入工作岗位, 所以不是工作时间影响创造力,但也不是年龄制约了创造力


请问对于问题:”choosing between the competing explanations“, A的YES/NO可以回答该问题吗?尤其是如果回答NO, 根本没有做出任何选择阿, 只是说两者都不是, 但问题不是问“choosing between”嘛。
请教!
