Whenever I am assured I have learnt something absolute in sentence correction, some gmat question creates ambiguity yet again.

As per my understanding, whenever we have a comma+conjunction form, it indicates the beginning of a new clause, meaning the noun/pronoun+verb form must exist.

In the correct answer choice, we find that after 'part of the Andes' comma+conjunction form is present, indicating that there should be clause following the conjunction. However we find no clause but rather "........., and, over the past decade, has made a remarkable comeback." Where is the subject/noun/pronoun ? For D to be correct, there must be no comma prior to 'and'.

I request an expert to help me with this predicament.

1 The rare bird, considered extinct for fifty years and actually thriving in a remote part of the Andes, has made a remarkable comeback over the past decade.
2 The rare bird, which had been considered extinct for over fifty years but it was actually thriving in a remote part of the Andes, has made a remarkable comeback over the past decade.
3 The rare bird, which was considered extinct for over fifty years and had actually been thriving in a remote part of the Andes, made a remarkable comeback over the past decade
4 The rare bird was considered extinct for over fifty years, but it was actually thriving in a remote part of the Andes, and, over the past decade, has made a remarkable comeback.
5 The rare bird was considered extinct for over fifty years, was actually thriving in a remote part of the Andes, and, over the past decade, has made an remarkable comeback.


Quote:
A) The rare bird, considered extinct for fifty years and actually thriving in a remote part of the Andes, has made a remarkable comeback over the past decade.
C) The rare bird, which was considered extinct for over fifty years and had actually been thriving in a remote part of the Andes, made a remarkable comeback over the past decade

We require a contract conjunction i.e. 'but' so A and C are Incorrect. Plus, C switches the verb tense and makes the meaning illogical. Both are OUT.

Quote:
E) The rare bird was considered extinct for over fifty years, was actually thriving in a remote part of the Andes, and, over the past decade, has made an remarkable comeback.

This sentence creates a superficially parallel list that alters the meaning of the sentence, and also makes it illogical. OUT.

Quote:
B) The rare bird, which had been considered extinct for over fifty years but it was actually thriving in a remote part of the Andes, has made a remarkable comeback over the past decade.

'it' is redundant in the sentence as the subject is 'The rare bird' and can simply use a conjunction to connect compound verbs. D is a better option, so this one is OUT.

Quote:
D) The rare bird was considered extinct for over fifty years, but it was actually thriving in a remote part of the Andes, and, over the past decade, has made a remarkable comeback.


The Core -> The rare bird was considered extinct, but it was actually thriving and has made a remarkable comeback.
The Structure is Independent Clause, 'Conjunction' + Clause with Subject and Verb 1, Modifier, Clause with Verb 2.
The 2nd clause 'it was....comeback' maintains parallelism with 'was thriving' and 'has made'.
No other errors.

D is the right answer.

OreoShake, while I agree that the commas are overdone in D, it's also true that there are very few absolute rules in English grammar! Like it or not, sometimes writers--even GMAT writers!--will insert a comma that doesn't seem necessary. Remember that commas can serve to indicate a pause in speaking and are sometimes used to break up a sentence for greater clarity. Honestly, I was tempted to put a comma before "and are sometimes" in that last sentence, even though it's not the standard! (What do you think? Would it have made the sentence easier to read?) For a good example of a "stray" comma in an official question, see this post (including my comments): https://gmatclub.com/forum/covering-71- ... 06346.html

While, I picked D cuz the meaning in (a) the better grammatical sentence was poor. I have a bit of an issue with putting a conjunction (and) changing the verb tense and having no subject before it.

Is this allowed in English? I always thought when you do parallelism you had to keep the same tense. So normally, in English when I change tense I would have put an "IT" before has made.

My corrected sentence would be:

The rare bird was considered extinct for over fifty years, but it was actually thriving in a remote part of the Andes, and, over the past decade, it has made a remarkable comeback.

1 The rare bird, considered extinct for fifty years and actually thriving in a remote part of the Andes, has made a remarkable comeback over the past decade.
2 The rare bird, which had been considered extinct for over fifty years but it was actually thriving in a remote part of the Andes, has made a remarkable comeback over the past decade.
3 The rare bird, which was considered extinct for over fifty years and had actually been thriving in a remote part of the Andes, made a remarkable comeback over the past decade
4 The rare bird was considered extinct for over fifty years, but it was actually thriving in a remote part of the Andes, and, over the past decade, has made a remarkable comeback.
5 The rare bird was considered extinct for over fifty years, was actually thriving in a remote part of the Andes, and, over the past decade, has made an remarkable comeback.

A conditional clause is required, hence choices not containing but can be removed, so ACE can be removed.
between B and D, D wins due to parallelism. In B "it" is not required.


Why is it not required? We changed tenses and we used a conjunction. I always thought when you change verb tenses that you need to add the subject back in to be clear.

However, I picked D because the meaning was crystal clear unlike A but I am not 100% happy with D and I think it contains an error that the actual GMAT wouldn't have.

On top of that in (D). I thought parallelism typically means that you don't change the tense. So I am not sure if D is correct even if you drop the comma. I also believe you're rule is correct.

I do think (D) is the best of the 5 still. But I do agree that this seems to be an error.
