Hi fistail, the last phrase says :
wingspan of 36 feet,believed to be the largest flying creature the world has ever seen.

Now,how does 'believed to be' modify wingspan...it clearly talks about the creature and seems ok to me.I think 'Believed' is acting as a participle and modifying Quetzalcoatlus...any thoughts??

Ant thing thats wrong with A is the tense...It should be present perfect as the belief still exists.

i dont think it is a matter of whether the belief still exists. if it were, the have would modify beleive (have believed)

i thought abuot this last night and the OA C is correct because we are in the present looking back. thus have been.

to be the worlds largest creature
to have been the worlds largest creature.

the sentence ends with,
the world has ever seen....
this suggests that this is the largest bird seen till date......a continuous process....
also, in option a, 36 feet is followed by believed to be ...use of pronoun it makes it more clear....

so the corrrect option is C

36 feet,and it is believed to have been the largest flying creature the world has ever seen.

(A) believed to be
(C) and it is believed to have been

This question has been discussed many times before but there were two different OAs. In my opinion, A is correct because it is a participial phrase modifying the subject in the independent clause.

Can anyone tell me why A is wrong?

According to the stem - the Quetzalcoatlus is very very extinct. So it cannot be. I had been.
Thus it is C.

I would appreciate further comments. Is my reasoning correct??

If you look at the last part of the sentence beginning with "believed to be..." this does not create a complete sentence. It seems to be an appositive such as "Allen, believed to be the smartest person in the world, still only scored a 790 on the GMAT!" There are modification and sentence fragment issues if the appositive "believe to be the smartest man in the world" is put at the end of this sentence such as "Allen still only scored a 790 on the GMAT, believed to be the smartest person in the world."

A cannot be correct because it keeps the phrase at the end where it is unclear what it refers to. What is believe to be the..? It appears that the object modified is wingspan in the manner it is written with A.

C corrects this problem by adding "and it is". This makes the whole thing a compound sentence by making the part after the "," a complete sentence. This is a much better, less confusing way of writing the same idea.

Any takers?

(A) believed to be - incomplete as verb to be is required.
(B) and that is believed to be - ambiguous referent for that.
(C) and it is believed to have been - similar to B.
(D) which was, it is believed, - incorrect idiom "believe".
(E) which is believed to be
- correct idiom "believe to be".

D and E are out since Which is wrong since it refers to wings
A is wrong

in B that is wrong
C is correct !!!

C is correct

To join two independant clauses we can use a semicolon (;) OR a comma followed by coordinating conjunction (and, but etc).
So we are left with choices B and C
'that; in B is ambiguous, so we are left with choice C

OA is C
Any explanations?

here that is not gud but ,and it is correct construction

X is believed to be the best of the lot
X is believed to have been the best of the lot

have been means referriing to past ,here we need a past tense hence C is better !!!

IMO A....

Disagree. C is my pick

A does not fit well because if you take the dependent clause out the sentence falls apart.

D & E use which incorrectly to refer to Q.

B uses that to refer to Q. it is better than that. Hence C

Re: the Quetzalcoatlus [#permalink]  27 Apr 2009, 18:50
I think "the Quetzalcoatlus had a wingspan of 36 feet" is a middleman and can be removed before you try to put the fragments in parallel.

Finding parallel to "A huge flying reptile that died out" , "and that is believed to be" fits in quite well.

Re: the Quetzalcoatlus [#permalink]  27 Apr 2009, 21:11
(A) believed to be - Modifier issue
(B) and that is believed to be - this is good because "that" is referring to "reptile" - no pronoun issue. But use of "to be" is wrong because "to be" refers to present tense.
(C) and it is believed to have been - "to be" issue is solved here but erroneous pronoun "it" could refer to "reptile" or "Quetzalcoatlus ".
(D) which was, it is believed - Modifier issue
(E) which is believed to be - Modifier issue

Here B and C could be parallel contender. I do not think this is a credited question.

you have to say have been because it is extinct

can you vindicate use of "it"

"it" is not ambiguos here because there is nothing else in the sentence to confuse "it" with.."it" clearly refers to the dinosaur

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

Re: the Quetzalcoatlus [#permalink]  28 Apr 2009, 07:25
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.
