Concept tested : Proper use of Co-coordinating conjunction
but is the correct conjunction to be used here as we intent to express contrast. This leaves us with B and D. In B past perfect tense is used , however we don't intend to express any sequence in time. Notice that the non underlined part of the sentence use present perfect correctly as we want to establish a time line from the past to the present. Hence D wins. Also don't worry too much about comma placement in D as GMAT doesn't judge an answer on that basis.

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.

I am gonna split the correct answer only:

The rare bird (subject)was considered extinct for over fifty years(first), was actually thriving in a remote part of the Andes(second), and[, over the past decade, MODIFIER] has made an remarkable comeback(third).

Hope this is what you were looking for

Hi, Zarrolou!

Are you sure you've split the correct answer? The my mind, the correct answer is D. The answer you've chosen (E) contains an erroneous article "an" before "remarkable".

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.
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.
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
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.
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 a remarkable comeback.

The bird was considered extinct, but was still thriving somewhere. To show contrast, a contrasting conjunction is required; hence A and C are out.

E has a list of clauses joined by ',' and 'and'. The option does not highlight the contrast. The three clauses are not even parallel as is required because of the list structure. The bird: was considered, was thriving, has made - all three clauses need to start with 'was', but this will make the sentence nonsensical.

That leaves B and D. The conjunction 'but' requires the two clauses it joins to start with the same word.
B. The bird: which had been considered, but it was thriving. which.., but it was... - Incorrect
D. The bird: was considered extinct, it was thriving - was considered..., but it was thriving... - Correct

I think the 'it' after but, in both B and D, is unnecessary.
Experts, please correct me if I am wrong anywhere in the above explanation. Thanks!

Hi vjns

First, when you see "and" or "but", think about parallelism structure. Technically, we have structures
(1) contrast: A... but B....<== A and B have opposite meaning.
(2) Non-contrast: A .... and B....... <== A and B do NOT have opposite meaning.

However, we do not have any structure like: A...but B...and C.... The structure is very confusing,
A >< B and A || C
---OR---
A >< B and A >< C.
We don't know. That's why we HAVE to repeat the pronoun as in option D (repeating of "it").

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

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.
Wrong. We need a contrast meaning here --> "and" is not correct.

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.
Wrong. if the sentence were correct, "it" would be redundant.

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
"made" is wrong tense --> we need present perfect tense because of "over the past decade".

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.
Correct. The structure is: X was considered extinct, but X was actually thriving, and has made a remarkable comeback. ==> was thriving || has made. Both of them are opposite to "was considered extinct"

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 a remarkable comeback.
Wrong. We need "but" after "fifty years" to create a contrast meaning.

Hope it helps.

I think option B ("The rare bird, which had been considered extinct for over fifty years but it was actually ") can be eliminated
for the following reason -
we do not have an independent clause before 'but'.
if we use 'but' we should have this structure -- independent clause, BUT independent clause.

Please correct me if I am wrong. Thanks

Hi,

In B the time line change is not evident.

"had been considered" and "has made" show as if both are from the same era.

Option D corrects this error.

Also in option D:"The rare bird was considered extinct for over fifty years" is an independent clause. Hence using one of FANBOYS(but) makes sense.

In option B:"the rare bird" is already the subject. The "it" is completely unnecessary as the clause " was actually thriving in a remote part of the Andes" also refers to the same rare bird.

hence D makes perfect sense.

Regards,
Dom.
