I came across on one of the forums where these questions were posted, but couldn't find the explanation. So, posting it here, so that any of the experts can shed some light on them. Both are of same kind of questions but with different type of answers. I am confused & curious to know the reason.
Plzz! help.

Question 2. D

Same explanation as above

Only Option D has parallelism in "her" and "of"

A it is.

Possessive pronoun can refer back to subject or object noun. Possessive pronoun should be paid attention in the last when there is nothing esle to pick in the sentence. 'her' can refer to 'Mary Leakey's' or 'Mary Leakey'.

A is correct for parallelism.

I agree with the second one....the first one seems wrong

'her' is the pronoun used for Mary Leakey...not for Mary Leakey's work.... so options D and E can be eliminated

I've the same doubt. Experts please clarify!

'In addition to HER WORK on Y, X's contribution' looks like the correct modifier here...

Thanks for the reply, Brian - makes more sense with the inverted sentence.
