A is correct, past perfect followed by simple past.

agree with A


Suresh, why do we need a perfect tense here?

A,B and C use "had" which is not needed.
D and E use the correct tense, but both have problems. D uses "contemporary to" instead of "contemporary with". E is missing "thus", which is followed by conclusion (that the Neanderthals are contemporary with modern Homo Sapiens).

My answer is A.

The past perfect is required + 'with' is the preposition.

4/5

A.
1. I am not sure that we need past perfect, though
2. we need "thus" to show the intended relationship between the 2 sentence parts.
Good question.

Here are the OA and Explanation - how do you feel about the difficulty of this question? On a level between 600 and 800?

Below 600
600-650
650-700
700-750
750+

OA: D


Since both events in the sentence occurred simultaneously, “had” is not desired in A, B and C. “Homo sapiens” in B, and C cannot be referred by “that and/or which”. The correct idiom is “contemporary to” as in B, C, D and E not “contemporary with” as in A. D, the best answer, is correct in terms of idiom and tense.

I am confused between A and E. Whether we should use past perfect or simple past? (if time and sequence mentioned clearly).

700+. This one uses idiom and the final answer can be completely filtered based on the idiom usage. Since GMAC is trying to phase out idiom based questions, it's better if the answer choices can be structured to apply multiple rules (other than just the idiom) to arrive at the correct answer.

Re: GMAT Club Experimental SC 2-6 [#permalink]
Unnecessary use of perfect tense in A, B, C. No subsequent past event
E - Simply connects two clauses by 'and', suggesting they are independent of each other while the original sentence clearly implies a connection with 'thus'
Hence, D

IMO, difficulty level 600-700

This sentence belongs to 700+ group

I do not remember too much about "contemporary to", I confuse between D and E. Chosen D based on my sense. There are another reason that make E wrong, aren't there?
