The subject of the sentence is ‘group’, so the correct verb is ‘projects’ … this eliminates A, B, and C.

Also, the average is a fixed number. It is not a range.

Imagine someone average GMAT score is 730 (in multiple attempts).

We can say: His average score is between 720 and 740. CORRECT

But we can’t say: His average score is from 720 to 740. INCORRECT

Same deal here: So D is wrong.

Correct: E

One thing that I noticed about GMAT SC correction is that you very often have 3 answer choices with something in common and 2 answer choices with something in common.

D

The answer is E

The subject here is" An international group" which is singular so we have to use a singular verb .
Note that a noun in the prepositional phrase can not act as the subject of the sentence here "more that 2,000 scientists " is in prepositional phrase so can not be the subject of the sentence .
Next thing is the use of between and from
One point to note here is that the average will be a certain number it can not be spread across a range so that value has to come between some numbers , so here in this sentence we have to use between therefore D is rejected outright .


There is meaning error as well in D this choice suggest that the international group projects global warming to average rather all they do is project the average of global warming .

I want to summarize
1. collective noun, by defaut, will take singular . this means we can see on gmat sc some cases, in which collective noun take plural.
2. something is project to do
is good pattern. but we do not use
project something to do . this point is from oxford dictionary
3. average is a point and, so, can not go with from...to. "average" must go with "between a... b"

hard problem.

For Singular Subject we need Singular verb so A,B and C are out.

Between D and E, E is the right choice. D distorts the meaning of the original sentence. Original sentence doesn't talk about the average value but it talks about range value.

Arpit
