(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

Alright, here is my break down:

A. uses the correct idiom "believed to be" - best choice.
B and C are eliminated because of the unnecessary use of the conjunction "and"
D is out - unidiomatic (believed here makes it seem like the dead reptile has believed something! whoa!!!, that's freaky... ) and ungrammatical ( which was, it is believed?, please...)
Now, E uses the correct idiom "believed to be", however, I didn't really see the need of "which is".

Eaxplaination:-

If "AND" is not use before "the largest flying creature the world has ever seen" then it seems to modify "36 feet". That is why answer should be between B and C. Here C is more correct.

E it is.

A- modifies the wing span
B - That refers to the wing span again
C - wrong verb usage
D - same
E - though not structurally a great one, but has the least errors

I believe C is best.
A) pariticipial phrase improperly referring to "36 feet"
B) no pronoun to refer to "Quetzalcoatlus" and seems to improperly refer to "36 feet" again
D and E have "which" which refers to "36 feet" and is wrong
Only C has a personal pronoun properly referring to an inanimate object. C also does not have any verb tense problem because present perfect means that the "Quetzalcoatlus" is still believed to have been the largest flying creature on Earth.

C. "It is" clearly refers to reptile, not to his wings.

E is wrong by the same reason as other choices, not clear whether it is reptile or its wings believed to be....

I'll go with C.

(A) believed to be-what is believed to be? The creature or the 36 feet? belived to be? Does it still exist?
(B) and that is believed to be-that is? again that is not the best way
(C) and it is believed to have been
(D) which was, it is believed,-which can not refer to a phrase, just a noun, had the descriptive phrase,.... 36 feet .. been seperated from the name of the creature, then it might've worked.
(E) which is believed to be...same as above

C is the only one that connects two phrases. Also, have been......has seen. I am not sure if my explanation is best or correct, but thats the way I would've thought about this SC

A is correct here...

B, C seem to suggest that it was believed to be the largest flying xyz. but not anymore...from the stem, we cannot make that jump, so we need to go with simple past tense...A is correct, in D & E, which is vauge and I am very picky about using which...

A is correct..

think that A) is not correct cause it states"believed to be " which implies that the reptile is considered not to possess the same quality in the present. Additionally, Present simple is used correctly to state a fact.

I agree with lvb250. The answer should be C.

"believed to have been" sounds very natural. It is what people believe so far--the Quetzalcoatlus is the largest flying creature (they will continue to carry on this belief into the future unless they can find a bigger flying creature).

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

(A) believed to be (misplace)
(B) and that is believed to be (and generates another senteces and "that" is not the correct pronoun
(C) and it is believed to have been (and generates correctly another sentences - have been is correct because yesterday and today the idea is acepted
(D) which was, it is believed, (what is modifying???)
(E) which is believed to be (what is modifying???)

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

For this question you don't need to look at the first phrase as it is modifying the Quetzalcoatlus. So the stem can be simplified to be this:

The Quetzalcoatlus had a wingspan of 36 feet, ... the largest creature.

It is obviuose that you need an "and" to connect the two independent sentences.

C

Paul,

This is the first time my views are different than yours.
I agree choice D and E can be eliminated as they have "which" which refers to "wingspan" and is wrong. I think that "which" is referring to "wingspan" rather than "36 feet".

According to me, "believed to be" used when we have to denote present tense and "believed to have been" denote past tense.
Now as per the question stated, world still believes that reptile is still the largest creature in the world thus it will be more apt to use believed to be rather than believed to have been. Am i wrong in this context?

In case the above explanation is true then choice C is wrong and between choice A and Choice B, choice B has no pronoun to refer to "Quetzalcoatlus" and seems to improperly refer to "wingspan" again.

If i take your explanation, you mentioned that choice C is correct because
it has a personal pronoun properly referring to an inanimate object. Why "it" in choice C cannot refer to "wingspan".

guess this is from OG.

Reasons for eliminating other choices:

A : there should be a conjunction...some thing like and
B : tough to rule out but the use of 'that' is little odd
D & E: chagnes the meaning of the sentence..seems like which refers to the wings, rather

For something/somebody did sth in past, it should be:
sth/sb be said/ believed to V in present perfect tense
So I pick C.

I go with A b/c this choice avoids confusing reference.
B is out b/c I don't know what "that" refers to.
Same thing with C. I don't know what "it" refers to and "have been" is not parallel with past tense "had".
Similar with D, what is "which" and "it" referring to.
E is out b/c "which" refers to "36 feet".

C is clearly the best answer.

To make A correct, I probably will add "and is" before believed.
