Hi,
Now the Q..

1) verb- help vs helps
the verb refers to 'bone structure', which is singular and so should correctle be HELPS
A and D can be eliminated

2) pronoun IT vs THEY..
logically the pronoun refers to "bird-hipped dinosaurs", so THEY is correct.. An OBSERVATION on this slightly later
B, C, and D can be eliminated..
ONLY E left

ans E

However other flaws..

3) Modifier- having vs with
having is verb+ing, so modifies the entire clause.. Not correct here
so WITH is correct

Now on the pronoun THEY

The first usage of NOUN "bird-hipped dinosaurs" is in POSSESIVE form, so in many ocassion it has been seen that possesive form/Object does not directly refer to the SUBJECT pronoun..

Thanks Underlined the text.

I have a doubt here... " They" may also refer to paleontologists??

Thanks

Yes, you are correct..
Logically it should point to "bird-hipped dinosaurs" and Grammatically it points towards "paleontologists"...
since there is no BETTER choice, we will have to select logical view..

Fortunately, in ACTUALS, this situation would be rare..

The moment i glanced over the choices i saw 2/3 and 3/2 split of having/with, helpS/help and they/it.

As it is clear that "it" cannot refer to dinosaurS, hence we are left with A and E only.

Again help is wrong verb for Structure. So D is out.

Now E is the only choice left, which is correct.

Hi bhamini1,

Definition : Any relative pronoun such as that, which, who would ALWAYS refer to the NEAREST POSSIBLE ANTECEDENT. This antecedent is NEAREST POSIBLE PART OF THE SENTENCE NOT PART OF SPEECH.

Always take the help of the object whenever you see a situation like this. Pronoun abiguity whether "they" refer to "paleontologists" OR "dinosaurs" is actually not there if you read "they evolved independently of other dinosaurs", which is very clear in its meaning.

So definitly 'THEY' doesn't refer to anything BUT dinosaurs.

Hope it is clear.

It / They
Since bird hipped dinosaurs is plural.. they will be refer to them.
BCD / AE

help / helps
The bone structure is singular and hence must use a singular verb helps.

paleontologists / paleontologists'
paleontologists believe is correct
CD / ABE

believing / believe
CD / ABE

Bone structure(singular) of type of dinosaurs,is helping the paleontologists to explain how they evolved, With the intent in mind

a) having pubic bones which point downward and toward the tail, help explain why paleontologists believe that they
Singular subject plural verb mismatch

b) having pubic bones which point downward and toward the tail, helps explain why paleontologists believe that it
Plural subject (dinosaurs), singular pronoun mismatch

c) with pubic bones which point downward and toward the tail, helps explain paleontologists' believing that it
believing, not the intent of the sentence

d) with pubic bones which point downward and toward the tail, help explain paleontologists' believing that it
Singular subject plural verb mismatch

e) with pubic bones which point downward and toward the tail, helps explain why paleontologists believe that they
All errors fixed
