C it will be ...

the sentence uses '' the quetzalocatlus HAD a wingspan'' the use of ''HAD'' makes it past perfect and the sentence should be in perfect unision with the tense flow....


A) ''believed to be'' does not sound right and lacks a pronoun too

B) seems right but the use of ''that'' does not substitute for the right pronoun...

D) the use of ''which was'' tries to say ''the wingspan'' and not the Q.....s was the largets flying reptile or watever...

E) same confusion...

C) has ''it'' pronoun reference and also the use of ''have been'' suits for the use ''the world has seen '' both of which are in the past tense...


any other expalnation is welcome pls...

hope that helps!

Have fun :)

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.

(A) believed to be

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....

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 - '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'

Here's the explanation.

Let's consider the question stem, specifically the underlined part. Here, 'believed to be' is an adjective modifier/clause and it is supposed to modify the noun 'Quetzalcoatlus'. However, the adjective modifier/clause should modify the noun immediately before. In this case, the noun before it is '36 feet'. Hence the modifier incorrectly modifies the wrong noun.
Now, let's look for an answer which will resolve this issue.

Option A - incorrect for the reason mentioned above.

Option B - This option connects the clause 'believed to be ...' using the conjunction 'and'. However, 'that' in the answer incorrectly modifies the clause 'the Quetzalcoatlus had a wing span of 36 feet' instead of only modifying the noun 'Quetzalcoatlus'. Hence this is incorrect as well.

Option C - This option correctly modifies the noun 'Quetzalcoatlus' by using the pronoun 'it' for reference and connecting the adjective modifier using the conjunction 'and'.

Option D - this is very ambiguous and also incorrectly uses the relative pronoun 'which' to modify the noun '36 feet' immediately preceding it.

Option E - this option also incorrectly modifies the noun '36 feet' immediately preceding the adjective modifier 'believed to be ...'.

Hope this helps.

Cheers!

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
Incorrect: This is saying that "36 feet" is "believed to be the largest flying creature the world has ever seen. Incorrect modifier.

(B) and that is believed to be
Incorrect: The use of "that' is incorrect. "That" cannot refer back to the reptile. "It" would have to be used instead.

(C) and it is believed to have been
Correct:

(D) which was, it is believed,
Incorrect: Again, incorrect modifier. Says "36 feet" was believed . . .

(E) which is believed to be
Incorrect: Modifier issue again

I do not think the antecedence of the pronoun ‘it’ is a great problem to decode. Its object is a living creature and a wingspan cannot be a creature. So, the reference falls on the dinosaur


Hi Daagh,

I chose option B as I was not sure that the usage of "have" in option C is correct or not.

Can you please explain "have" is used in which I context here. I don't see any plural subject in the sentence.

Thanks,

Hi,

Let's take a look. It seems like we are dealing with modifiers.

3. 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
this is inappropriately referring to 36 feet when it should refer to the reptile
(B) and that is believed to be
Incorrect. What is that referring to? It could refer to the wingspan but we want a pronoun to refer to the reptile
(C) and it is believed to have been
Correct, put the Quetzalcoatlus in for "it" and this reads well
(D) which was, it is believed
Wrong because which is inappropriately referring to 36 feet
(E) which is believed to be
Wrong because which is inappropriately referring to 36 feet

Let me know if you need more advice on this.

Happy Studies,

HG.

Would like to go with (B) on this one (High chances that I am wrong!!! :roll: ) but looks like proper parallel structure and without any improper referent (as is present in choice (C), "it" has no clear referent I presume ---> "it" can refer to Quetzalcoatlus or to wings)

Correct me If I am wrong? (Definetly many try to do so!! :) )

(C). It properly modifies the flying creature (can't remember how to spell it :lol: ), and have been indicates that it was the biggest flying creature then and still is the biggest flying creature (although it is now extinct, no other flying creatures has surpassed it in size)

'believed to be' indicates that Quetzalcoatlus still exists, but the real meaning is that it is still considered a largest flying creature (present perfect).

C it is.

Agree with C as it is the only choice which introduces a personal pronoun to refer to the Quetzalcoatlus. A's participial phrase and B,D and E's relative pronoun improperly refers to "wingspan" and hence make the wrong comparison
