A: A universal factor needs a present tense ’is’ rather than past tense ‘was’

B. ‘drift itself was ignored until physicists produced compelling’ – when two events occurred, one earlier than the other, the earlier one requires past perfect

C: was is wrong tense

D: same as in C

E: Proper usage of past perfect tenses; Correct choice


Answer: E

Could someone please explain why in some cases such words as 'until', 'before' are enough for not placing the verb into the past perfect tense (only past simple is required), and in other cases these words are not enough and I still need to use past perfect?

I feel answer B is correct as well. The use of the word "UNTIL" is a clear time marker which indicates that the concept was ignored before scientists produced compelling evidence.

Past perfect is used to depict an earlier action. The action "ignoring" occurred before the action "producing".

You may also observe similar sequencing in the previous section of the sentence: "drawing" occurs before "transforming".

Also please note the exception that the usage of past perfect would not be required when the sequencing is made clear by using "before" - there is no "before" in this case. When "until" is used , past perfect tense is still required.

sayantanc2k, could you pleas explain why "until" doesn't work a clear sequencing indicator here? X was until Y, clearly states that X was before Y; other options are not logical.

It would probably be best to take the use of "until" as a grammatical rule - (use of "until" is more complicated for the past than it is generally thought of):

When the use of "until" is in future, the structure is: future + UNTIL present perfect / present
We will not leave until you finish.... correct
We will not leave until you have finished... correct

When the use of "until" is in past, the structure is: past + UNTIL past perfect OR past perfect + UNTIL past
There is a peculiar thing about using UNTIL in past. The verb after UNTIL could be the prior action or the verb before UNTIL could be the prior action.

We stayed until he had finished..... correct (the verb after UNTIL is the prior action)
We had never considered him a kind person until we knew about that incident...... correct (the verb before UNTIL is the prior action)

In either case the use of past perfect would clearly indicate which is the prior action.

There is one more use of "until": past perfect continuous + UNTIL past
We had been feeling sad until he gave the news. ( in this usage as well the verb before UNTIL is the prior action, but the difference is that the progressive nature of the verb is highlighted.

I think this is a high-quality question and I don't agree with the explanation. Why is option B incorrect. since usage of UNTIL already establish the sequence of the events, usage of "was ignored" should be sufficient.

Here are 4 actions in pair.

drawing and transforming
and
Ignoring and producing compelling evidence.

Is it require to establish the sequencing in between the pairs?
as it is easily understood which actions took place first but on GMAT does the answer choice which explicitly establishes the sequence is more preferable.

does the 'had never drawn ' and 'had been ignored' establishes the required sequence in OA.
Please give the expert opinion as I am confused when the two actions are acceptable as independent (on GMAT) and when are not.
