'could date' and 'could explain' need to be parallel. Also, 'such as having' is unnecessary. 'features' infers the hominid's have a large brain and small teeth.

Hence, IMO, answer is B.

D makes it seem as if fire explains hominid features when it should be the use of fire to cook could date back and explain as in B

so B

thanks ... this explanation is perfect.. I guess in the time pressure I missed this point. I should have spent few more secs to see this error as to who is doing the 'modifier'...

OA is B.

Though I marked the correct OA, but it took me 3:28 min to make out the meaning.
I marked B for:
1. could date....could explain
2. the use of fire to cook food - (a noun phrase) is a method which can be traced back not the fire
3. such hominid features as Vs like


I hope in the real GMAT such questions are not for me :)

Generally speaking you can eliminate A because it uses 'it' and i can't find any antecedent for it.
In D and E are not correct because of it'e meaning fire used . What does this mean. Some other fire was being used millions of years ago or what ?
I eliminated C because Like can't be used to give examples so B is the answer. Notice B has everything going fot it.

Expert's post
To keep things Simple, Just consider what can be dated back ? the use or the fire?
Of course the use can be dated back so and so years ago. B explicitly says that. A is a montstrocity and can never be correct on the exam

Re: sc doubt 2 [#permalink] New post 26 Dec 2014, 09:09
There is a 3/2 split in the use of the verb be dated/date. The option date back, seems to point to the fact that fire has been used for cooking for almost two million years, not that scientists now can date back the use almost two million years back. It therefore distorts the meaning and can be excluded. E sounds awkward, so the original version remains.

Answer A.

Answer A.


E isn't just awkward, it has a nonsensical meaning:

fire used for cooking food could be dated back to almost two million years and explain hominid features like

implies: fires used for cooking food could be dated back to almost two million years (okay), and fire used for cooking food could explain hominid features (what?). It's not the fires that could explain hominid features, it's the USE of fires could explain the features.

A. using fire to cook food could be dated back to almost two million years and that it could explain hominid features like having
It has no clear antecedent, "could be dated back" is less wordy and less clear than other option

B. the use of fire to cook food could date back almost two million years and could explain such hominid features as
Seems ok, hold it.

C. cooking food with fire could date back to almost two million years, explaining hominid features like
use of "like" to introduce examples isn't the best.

D. fire used to cook food could date back almost two million years, explaining hominid features such as having
Distorted meaning: fire is explaining hominid features?

E. fire used for cooking food could be dated back to almost two million years and explain hominid features
Distorted meaning (see above).

Pick B.
