CR: On the whole, scientist do their most creative work

[cesar.rodriguez.blanco]

I do not understand how to solve this CR. Please help!

Which of the following most logically completes the passage?
On the whole, scientist do their most creative work before age of forty, a tendency that has been taken to show that ages carries with it a loss of creative capacity. An alternate explanation is that by age forty most scientist 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 scientist who produce highly creative work beyond age forty entered their field at an older age than is common
C) many scientist 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) a scientist 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

IMO : B

Paraphrasing:

conclusion : Scientists' Creativity decreases with Time.
In order to support this conclusion Author says " Most scientist by the age of forty have 15 years of experience, that exhaust the opportunity of creative work in the field".

We have to find something that support Author Saying ..

a) Irrelevant.

b) Scientist who produce creative work after the age of forty, entered in the field lately. --> Means by the age of forty, they have not finished the 15 year of experience, so they still find opportunities. This is supporting Author.

c) says scientist do their work with a believe that their creativity will decrease with age. But this has nothing to do with Author saying.

d) This doesn't fit in the passage. Grammar Error : A scientist Who "are", LOL..
In terms of meaning, I found this is close.
Scientist after the age of 40, find more satisfaction in other activities than research; Again if they are not satisfied, this doesn't mean there is no opportunity for creative work.

5) Irrelevant, Talking about the other fields.

What is OA ?
