The plateau in global warming that took place in the 1950’s and 60’s is still not well understood; however, evidence from several Notre Dame researchers suggest that sunlight-blocking pollution from dirty factories may have played a role, just as natural variability did in ocean circulation.

A. understood; however, evidence from several Notre Dame researchers suggest that sunlight-blocking pollution from dirty factories may have played a role, just as natural variability did in ocean circulation

B. understood; however, evidence from several Notre Dame researchers suggest that sunlight-blocking pollution from dirty factories may have played a role, in the same way that natural variability did in ocean circulation

C. understood, but evidence from several Notre Dame researchers suggest that sunlight-blocking pollution from dirty factories may have played a role, as natural variability did in ocean circulation

D. understood, but evidence from several Notre Dame researchers suggests that sunlight-blocking pollution from dirty factories may have played a role, as did natural variability in ocean circulation

E. understood, but evidence from several Notre Dame researchers suggests that sunlight-blocking pollution from dirty factories may have played a role, as natural variability may have in ocean circulation

here evidence is subject it must follow verb
singulair verb suggests,
so option A, B and C is wrong.

In option D and E,

usage of As is used to compare clauses with same entity,

In option D , ellipsis is used.

sunlight --may have played role, as sunlight did. so option D is correct.

option E, sunlight compare with natural variablity . so option E is not correct.

ans OA is D

My question is that : is 'evidence 'here is singular or plural. Are several scientists using one evidence or many.

what is the plural of evidence?

thankyou in advance.

Yes, you are right. Here one "evidence" is meant and the singular verb "suggests" is correct.

Plural of "evidence" is "evidences".

Hi expert,
Why option E is wrong
Considering that the comparison is in proper form as + clause,thus the actions of two different doers are compare?
Is it because of tense: present vs simple past? And if so,what is the clue to choose between them
Please advice :( :(

Thanks for your consideration


There is no uncertainty that natural variability played a role in ocean circulation. Therefore the verb "may have", which indicates uncertainty, is incorrect. Hence option E is wrong.

Hi sayantanc2k:
What about the comparison? If the tense was OK,then, how can we eliminate E?
Suppose E was as follows:
understood, but evidence from several Notre Dame researchers suggests that sunlight-blocking pollution from dirty factories may have played a role, as natural variability may have did in ocean circulation
Then would you choose E or still prefer D?

Appreciate your input.

In that case E would be same as D with subject and verb flipped - both are equivalent. (There is no parallelism issue in either.)

VERITAS SOLUTION
In this problem it is relatively fast and easy to eliminate (A), (B), and (C). “The evidence…suggest” is wrong – it needs to be “The evidence…suggests” However, the choice between (D) and (E) relies almost exclusively on meaning and is thus confusing. The logical meaning is that the evidence suggests that some pollution played a role as well as a natural variability in ocean circulation. (E) is illogical (but sounds more parallel to many people!) as it states that pollution may have contributed to the plateau and - randomly – natural variability may have played a role in ocean circulation - a clear case of illogical predication! Only (D) creates logical meaning and uses a proper structure to do so. Answer is (D).

A. understood; however, evidence from several Notre Dame researchers suggest that sunlight-blocking pollution from dirty factories may have played a role, just as natural variability did in ocean circulation

B. understood; however, evidence from several Notre Dame researchers suggest that sunlight-blocking pollution from dirty factories may have played a role, in the same way that natural variability did in ocean circulation

C. understood, but evidence from several Notre Dame researchers suggest that sunlight-blocking pollution from dirty factories may have played a role, as natural variability did in ocean circulation

D. understood, but evidence from several Notre Dame researchers suggests that sunlight-blocking pollution from dirty factories may have played a role, as did natural variability in ocean circulation

E. understood, but evidence from several Notre Dame researchers suggests that sunlight-blocking pollution from dirty factories may have played a role, as natural variability may have in ocean circulation


So whats the intent here talking some evidence which have made all the difference in understanding a phenomenon

Evidence will be singular, We can eliminate A, B & C, because they use a plural verb suggest

D. understood, but evidence from several Notre Dame researchers suggests that sunlight-blocking pollution from dirty factories may have played a role, as did natural variability in ocean circulation
as did, mentions that even natural variability played a role

E. understood, but evidence from several Notre Dame researchers suggests that sunlight-blocking pollution from dirty factories may have played a role, as natural variability may have in ocean circulation
its not indicating what natural variability did here.

E
