Modifier "Digging in sediments in northern China" should change anything that comes after it.So here evidence is being modified by this phrase but that is clearly not the intended meaning.Evidences can not themselves dig something rather scientists are digging up evidences.This leaves us with choice (C) (D) and (E)

(C)Perfectly written.Present perfect and then Past tense.Earlier error of Past Perfect has been taken care of.
(D)As per 'VAN' rule Verb Adjective/Adverb and then Noun.We have a verb that is there in the option C also "than that which was" is totally confusing
(E)Same as D.Also "than that" is not properly construct

With this question we can quickly home in on the 2:3 split. Notice the participial phrase beginning 'digging...'. The word that comes directly after the comma must describe who is doing the digging. Clearly it is the archaeologists, not the evidence, that is digging. Thus we can eliminate (A), (B).

Both (D) and (E) are filled with unnecessary verbiage. (D) 'than that which..' and (E) '...than that.' We simply need a phrase that modifies 'emerge.' 'That' is used to describe comparisons between nouns. 'That' is a pronoun that is used to refers to a noun. Therefore (C) is best: 'emerged...than previously thought.'

Hi,

Although I choose C, but I am always confused while choosing Gerund.

In Between C & D, please explain which is better "Evidence Suggesting" or "evidence that Suggests" and why?

Please let me know if there is any article on this topic so kindly let me know.

suggesting is not playing a role of verb+ing modifier then can we use two verbs in the same independent clause ?
with subject-scientist verb 1 -digging, verb 2- suggesting ?
please clarify.

Yes indeed it is the modifier(present participle) modifying evidence Just before it.

Just to add this discussion- Emergence(noun) emerged(verb ) flipped in different ans choices ..
please keep an eye for shorter forms that is verb . Maxm chances verb form sentences will be correct.


I have doubt .. Is "a much" is wrong? should we always use 'Much'.
A much better way than.... Is it correct ?
much better way than... . Is this correct.?
if both are correct which one to prefer.

"that" is used to compare 2 different nouns, so it has to be used in paralel structure. "that" is never used as stand alone pronoun
"it" is used to compare the same noun at different context.

so

"that which" is never correct on gmat. remember this mechanically .

"that" pronoun is used to refer to a noun different from prevous noun and is used in paralel pattern. When parallel pattern can be tolerate, "that" must be refer to a noun clearly.

in D and E, there is no parallel pattern and it is not clear "that " refer to which noun. this is the real reason which makes D and E wrong.

Modifier error- digging... followed be 'who is doing the digging'- scientists. Then look out for the best answer choice. C is the best

parallel phrase make pronoun "that" clear and unambiguous. "that" can be used in non parallel stucture if the context make "that" unambiguous. There is one gmatprep question which show this acceptable non parallel pharase.

in D and E "that" is ambiguous.

so, be carefull of "that" pronoun and never underestimate the og and gmatprep problem. some questions seam to contradict one another but the are beautiful terriblly.

now, I am highly interested in discussion of official problem. the bad news is that gmat force us to infer the rule.
