D for me.

"probably to help it" refers to the bird (Confuciusornis Sanctus).

You can read it like this:

One of the earliest known birds with a beak and contour feathers, Confuciusornis sanctus, had large clawlike “thumbs” on its wings, probably to help it climb up to a launching position for flight.

B, E are out --> Sub-Verb agreement. Singlular Subject (one of the birds.. Confuciusornis sanctus.. is)
A,C are out-- them vs it (shuld be singlular)


D is Correct answer

Actually it is singular because of the of the subject ONE...

D is the correct answer here

both D and E hinge on the subject verb agreement

E commits an error of subject verb agreement


what is the OA for this

First of all by POE :)
Secondly, 'it' seems to modify here only 'One' as does 'its'. Reference to 'a beak' is too odd :shock:

But why it is not "probably helps it..." or not "prbably helping..."? Thanks!

Hi Sendoso,

It's a matter of POE to answer this.

A and B are wrong because "with a beak and contour feathers, Confuciusornis sanctus, with large clawlike..." is awkward. If it was going to keep this pattern, then it shouldn't separate beak, feathers and clawlike "thumbs".... they should all be listed together. So this rules out A and B because "had bla blah blah..." is correct.

E is out because "their" (plural) doesn't agree with birds/Confuciusornis sanctus (singular; "birds" here is singular). So E is gone.

Now, only left with C and D. Your idea of "probably helps it..." or "probably helping..." would work, IF either of those were an option. But their not. So we're left at choosing between C "...which probably helped them" or D "probably to help it". In C, "them" (plural) doesn't agree with "Confuciusornis sanctus" (singular), so C is eliminated. Only thing left is D, which works just fine ("it" is singular and refers back to the bird which is also singular). Although D may not be the way I would say this, after POE, it's clear that D is the only clear and concise answer choice.

Hope this helps!

note the use of "had", that can be the reason.

This is the first one with a verb. This would be the answer if it weren't for "them". This is not proper noun/pronoun agreement. "its wings" should then require "helped it".


Hi Jallenmorris,

You are the man!!!!
I agree with your comments

In option C, Eventhough if we replace "them" with "it" setence is not logical, because modifier "which" incorrectly modifies the wings.
--->means---> wings helped it climb up to launching postion for flilght
but actually "the claiwlike thumbs on wings" helped it cllimp up to launching postion for flight.

Correct me if I am wrong.

I think the way you corrected the setence is correct. It makes sense and the noun/pronoun agreements follow the rules.

I agree with "elminate the middleman". That's great advice!

D&E are gone because of the singularity(it) association with birds.

I think many have missed "sondenso's" question. Obviously D is best for correct pronoun reference "it" for a singular bird "Confuciusornis sanctus". Not necessary to say that A and B that start with "with" are easily ruled out. C and E have incorrect pronoun references "them for it" and vice versa. So D remains and is correct as already reveled the OA.

So far as to his/her question about modifier - "it or its" cannot refer to any other thing (for ex: wings or thumbs) than Confuciusornis sanctus. So "probably to help it" modifies "Confuciusornis sanctus".

D is the best one, obviously

108. One of the earliest known birds with a beak and contour feathers, Confuciusornis sanctus, with large clawlike “thumbs” on its wings, which probably helped them to climb up to a launching position for flight.

A. with large clawlike “thumbs” on its wings, which probably helped them to
B. with large clawlike “thumbs” on their wings, which probably helped it to
C. had large clawlike “thumbs” on its wings, which probably helped them
D. had large clawlike “thumbs” on its wings, probably to help it
E. had large clawlike “thumbs” on their wings, probably to help it

The use of probably to help it in D & E is better than the use of which probably ... in A, B & C because which here (in 3 choices) stands right behind wings, so it will wrongly modify for wings that wings help the Confusiusornis sanctus to ...

More precisely, probably to help it correctly modifies for the whole sub-clause "Confuciu ... had large ... wings" meaning that the whole fact that Confuci ... have a clawlike ... on its wings helps it to ..., not only the wings that help it to ...

Is it ok ?
