I, too, am having the same doubt, which is why I have requested
GMATNinja, in spoiler section, to clarify it.
Expert,
Please confirm whether the following understanding about tense issue in E is correct-
'Has'- present perfect- is inconsistent with 'had' - past perfect.
Further, in such case, isn't simple past - that began- sufficient? Or the sentence needs the structure- that had begun ?
Thanks!
There are a whole bunch of issues in here, and some of them don't seem to appear on the actual GMAT very often! The usual friendly warnings apply here about non-official verbal questions: GMAC spends somewhere between $1500 and $3000 developing each question, and even the very best test-prep companies can't quite compete with that.
I'm not sure if this is part of the issue, but for starters: "begun" in (B) isn't a verb at all -- it's actually an adjective. Consider these:
1. Burritos smothered in green chile make Charles happy. --> "smothered" sounds like a verb, but it's actually an adjective
2. Burritos eaten with unbridled joy will not make you fat. --> "eaten" sounds like a verb, but it's also an adjective
3. The project started by Amber in 1998 will be complete in 2019. --> "started" is also an adjective...
4. The project begun by Amber in 1998 will be complete in 2019. --> ... and so is "begun" in this case
More on these "-ed" words in this crusty old article:
https://gmatclub.com/forum/experts-topi ... 40280.htmlgmatexam439 is correct about the verb tense issues in (E). I'm not sure, but it sounds like part of the misconception might be that you're assuming that the word "had" automatically indicates the past perfect tense, and that's not quite right:
1. Domenico had a colonoscopy this morning. --> simple past tense
2. Domenico has had monthly colonoscopies since 2007. --> present perfect tense, indicating an action that starts in the past and continues in the present (presumably, Domenico will continue having monthly colonoscopies)
3. Domenico had had several colonoscopies before he decided that his rectum is exit-only. --> "had had" is past perfect tense, and must indicate an action that happens in the past, before some other action or "marker" in the past (in this case, "he decided" is the later action in the past, so this sentence is acceptable)

In this particular sentence, "begun" is just an adjective in (B), so that's completely fine. For (E) to be correct, "has begun" would have to be changed to "began", since the action of STARTING the attempt happened exclusively in the past. It would be wrong to use the present perfect "has begun", because the action of STARTING the attempt is already completed.
I hope this helps!
