Scientists typically do their most creative work before the age of forty. It is commonly thought that this happens because [b]aging by itself brings about a loss of creative capacity[/b]. However, studies show that a [b]disproportionately large number of the scientists who produce highly creative work beyond the age of forty entered their field at an older age than is usual[/b]. Since by the age of forty the large majority of scientists have been working in their field for at least fifteen years, the studies’ finding strongly suggests that the real reason why scientists over forty rarely produce highly creative work is not that they have simply aged but rather that they generally have spent too long in a given field.

In the argument given, the two portions in boldface play which of the following roles?

A. The first is the position that the argument as a whole opposes; the second is an objection that has been raised against a position defended in the argument.
B. The first is a claim that has been advanced in support of a position that the argument opposes; the second is a finding that has been used in support of that position.
C. The first is an explanation that the argument challenges; the second is a finding that has been used in support of that explanation.
D. The first is an explanation that the argument challenges; the second is a finding on which that challenge is based.
E. The first is an explanation that the argument defends; the second is a finding that has been used to challenge that explanation

Don't just give the answer, explain please. Even if it wrong it is OK, we learn by reasoning here.

I will go with 'D'
E - The first is not an explanation that the argument defends.
C - The second is not supporting the first bold face.
B - The first is not claiming anything.
A - The second is not an objection

Karun, can u plz check ur profile and perhaps make these changes. I think u r trying to put bold faces, underlines etc but they don't display as per ur settings. Go to Profile ----> and check for these and make sure they are all selected "YES".


Always allow BBCode: Yes No
Always allow HTML: Yes No
Always enable Smilies: Yes No

C. The first is an explanation that the argument challenges; the second is a finding that has been used in support of that explanation.

Considering C above, the first is an explaination alright, but the second, though a finding does not support the explaination given by the first. Rather, ithe second gives us a bases to challenge the first.

agree with (D)
