IMO C
A huge flying reptile that died out with the dinosaurs some 65 million years ago, the Quetzalcoatlus had a wingspan of 36 feet, believed to be the largest flying creature the world has ever seen.
(A) believed to be --> believe here will be incorrectly implied as verb for subject Quetzalcoatlus because it is also in past tense as 1st verb had, making the whole sentence having a wrong meaning
(B) and that is believed to be --> that here wrongly modifies for all the clause the Quetza ... 36 feet, while it should modifies only for Quetzacoatlus
(C) and it is believed to have been -->best choice. It clearly refers to Quetzalcoatlus. Is believed here is no problem because it reflects that such action occurs in the present time. Besides, present perfect here is correctly used because the 2nd clause is also parallel with a sub-clause the world has ever seen, modifying for the 2nd clause
(D) which was, it is believed --> which here refers to the nearest noun 36 feet, making the wrong meaning for the whole sentence
(E) which is believed to be -->the same error as D

IMO B, here are my takes-
(A) believed to be--if we use this, this fragment refers back to wingspan. This means that wingspan of 36 feet is believed to be the largest creature world has ever seen.
(B) and that is believed to be--Correct
(C) and it is believed to have been-- believe to have been?? it is still the largest so incorrect tense.
(D) which was, it is believed--No past tense, we need present tense to show that creature is the largest.
(E) which is believed to be--I almost had this but later figured that we need and before this conjunction, this refers to wingspan again. But I am little doubtful here.

Yes, C is better option

(A) believed to be - incorrectly placed modifier, closer to wingspan than to reptile.
(B) and that is believed to be - ambiguous use of that, not referring to the reptile
(C) and it is believed to have been - correct
(D) which was, it is believed, - use of was and is together. sounds awkward
(E) which is believed to be - sounds like wingspan is believed to be....

i think the question stem has to be corrected a little bit..

A huge flying reptile that died out with the dinosaurs some 65 million years ago,
the Quetzalcoatlus had a wingspan of 36 feet,
believed to be the largest flying creature the world has ever seen.


There shud be comma after "the Quetzalcoatlus " to make it a complete statement..

any thoughts?

I think option C is wrong because "it" can refer to either Quetzalcoatlus or wingspan. I really like the structure in option A for 1 main reason. I'll give you an example to explain what I mean:

1) The dog loves food, treated with great care and love.
explanation: because we have a comma after "food", "treated," which is a past participle, refers to the subject of the previous clause. So that subject of the previous clause is "The dog."


2) The dog loves food treated with great care and love.
explanation: because we DON'T have a comma after "food", "treated," which is a past participle, refers to the closest noun or to the attached noun. So that would be "food."

The first example is the logical choice! So that is the same reasoning I used to pick option A as my choice.

What's OA?

(A) believed to be---Seems awkard by to be , yet I think it is best answer.
(B) and that is believed to be-- That has no referent as which . Since which and that modifies the word that precede.
(C) and it is believed to have been--- Ask your self what is believed the Wingspan of Quetzalcoatlus or Quetzalcoatlus? No clear referent of it.
(D) which was, it is believed,Wrong since which has no clear referent
(E) which is believed to beb]Wrong since which has no clear referent[/b]


I'm not agree with OA , however this question needs to be clarified by an expert .

IMO C too
BUTTTTTTTTTT
this option uses "Have been"...which I feel is incorrect....have is a plural verb form
also have been...is incorrect use of tense....the animal lived in the past...and it is already gone


have in 'to have' is an auxiliary verb for infinitive form

have for 'perfect aspect'
be for 'used to form the passive voice and continuous aspect)

had a hard time between A and C, but after reading it again, A has the same problem as E, what is believed modifying? wingspan or the creature?

C because of the use of "and"...by parallelism, "it" refers back to the creature... but could anybody explain whether the usage of "have been" is right here?

A: Awkward.
D and E: Which needs to be directly behind Quetzalcoatlus to be grammatically correct.
B: "That" refers to The Quetzalcoatlus having a wingspan of 36 feet and does not refer to the reptile itself.
C: "It" refers to the Quetzalcoatlus. Present perfect "have been" is correct because the reptile was the largest flying creature 65 million years ago and still is the largest flying creature at the present moment. Correct.

I would go with C.

(A) believed to be - verb is missing
(B) and that is believed to be - what is "that" referring here.
(C) and it is believed to have been - Correct
(D) which was, it is believed, - wrong placement of which
(E) which is believed to be - wrong placement of which

(A) believed to be
(B) and that is believed to be
(C) and it is believed to have been
(D) which was, it is believed
(E) which is believed to be

C for me

A D and E - misplaced modifier - the phrases should modify the Quetzalcoatlus rather than a wingspan of 36 feet
B : that has no clear antecedent

I go with C
In this case "and it is believed to have been the largest..."
its not a normal present perfect verb....thers no verb ahead of it.. :wink: ..."to have been" here indicates some kind of compulsion ..."must"

read more below:
"Have is often combined with an infinitive to form an auxiliary whose meaning is similar to "must."

I will go with C too.

D and E are out because of "which" - which refers to the noun immediately preceding it.

A is wrong, because you are joining 2 independent clauses without a conjunction and it also does not have a verb

B is wrong because of "that"

Only C is left.

(C) and it is believed to have been --- if we assume that it could refer to wingspan then we cannot compare a wingspan to the largest creature. So it has to refer to Quetzalcoatlus only. Have been means that the belief is still valid that the reptile is largest flying creature.

C seems to be right, even though 'have been' is considered wordy by gmat.
The problem with the sentence is that it is missing a FANBOYS conjunction after the comma. [IMO]
We need to add an 'and' after the comma to make it a proper dependent sentence and only C is doing that.
So by POE, I would go for C on the test day any day.

Of all the options, C appeals to me more.
"and it is..." introduces a new clause, which emphasizes a new characteristics of the flying reptile.
Furthermore, "believed to have been..." rightly suggests that the reptile is still the largest
creature ever know to date.

A huge flying reptile that died out with the dinosaurs some 65 million years ago, the Quetzalcoatlus had a wingspan of 36 feet, and it is believed to have been the largest flying creature the world has ever seen.

C is the correct answer.
The present perfect in 'have been the largest' means that so far, there wasn't a bigger flying creature. It does not mean that the creature lives today (in fact, it was extincted long ago), but the world hasn't seen a larger flying creature until now.

Hey everyone,

I have this question from the 1000 SC thread and I have trouble understanding the answer. Also, if I am not wrong, the first 10 questions from the 1000 SC document and the answers provided in http://gmatclub.com/forum/1-1000sc-100-brutal-q-explanations-2-level-of-question-85402.html do not match.

Anyways, my question is:

8. A huge flying reptile that died out with the dinosaurs some 65 million years ago, the Quetzalcoatlus had a wingspan of 36 feet, believed to be the largest flying creature the world has ever seen.
(A) believed to be
(B) and that is believed to be
(C) and it is believed to have been
(D) which was, it is believed,
(E) which is believed to be

The answer is C. I am trying to understand why the answer is C. Is it because "have been" is parallel with "has ever seen"?

Thank you,

-Harsh.


hi harsh,
this is actually quite a simple question

here, 'which' is a noun modifier and so is 'believed' ... so both of them incorrectly modify "36 feet" ... whereas they should modify Quetzalcoatlus
so A, D & E are out

in B, "that" is not used correctly.
the use of "... and that .. " is not parallel because there's only one relative pronoun present.

the Quetzalcoatlus that had a wingspan ... and that ----> this would've been parallel

so we're left with C .... HTH

(A) believed to be - 'believed' is incorrectly modifying '36 feet'

(B) and that is believed to be - awkward

(C) and it is believed to have been - 'it' correctly refers to 'Quetzalcoatlus'. 'it' cannot refer to 'wingspan' because 'wingspan' is the object of the earlier clause. So the pronoun 'it' is unambiguously refering to the noun 'Quetzalcoatlus'

(D) which was, it is believed, - 'which' is incorrectly modifying '36 feet'

(E) which is believed to be - - 'which' is incorrectly modifying '36 feet'

beleived is a past participle ,threfore it should modify the noun immediately preceding it......
in A it is 36 feet ,.....which it isnot supposed to modify instead it is supposed to modify quetzalas....

also since this bird is still beleived to be the largest flyig bird so have been is correct hhere/......

hence C
