water molecules

by vscid » Fri Apr 09, 2010 6:02 pm
Theoretically, water could remain in liquid form indefinitely in extremely low-energy environments, prevented from evaporating its molecules as a result of an insufficient level of kinetic energy present in the molecules on the liquid's surface.

(A)prevented from evaporating its molecules as a result of
(B) prevented from having its molecules evaporated by
(C)its molecules prevented from evaporating by
(D)its molecules prevented from being evaporated as a result of
(E)preventing its molecules from evaporating by
The GMAT is indeed adaptable. Whenever I answer RC, it proficiently 'adapts' itself to mark my 'right' answer 'wrong'.

I will go with C. My reasoning is as follows:

A, B make the mistake of misplaced modifier where the subject of the first part of the sentence is water, which in turn is not prevented from evaporating but their molecules are, eliminated.

D unnecessary wordy and passive.

E changes the meaning of the sentence; it implies that he first of the half of the sentence causes the other phenomenon to happen.

very hard.

dont try to find why a choice is wrong, try to find why a choice is wrong when this choice is compared with correct choice. So, reading all 5 choices and looking for differences among choices are key mode.

between C and E what is more logic?

C mean "molecule is prevented" at the same time of remaining

E mean full previous clause (both subject, verb and the order of subject-verb) causes "preventing"

I see E is more logic

on SC, gmat test focuses on logic though grammar, gmat kind one, is also tested.

IMO C

E would have been correct if "Theoretically" was not used.

OA please ?

This question is plagiarized from OG Verbal Review 2nd Edition - Q108

IMO - C
I see similarity with below Q.
https://www.beatthegmat.com/sound-can-tr ... tml#242580
A,B - run on
D - usage of 'being', passive tone
E - does not make sense, there is no cause-effect relationship b/w 1st and 2nd half of sentence. The entire clause converted into NOUN Phrase should be able to function as the subject of the verb that is in -ING form preventing
I am on a break !!

IMO, A and B are not run-on, unlike what Suman mentions here. You need 2 independent clauses to make a run-on. I think the second clause in both A and B is not independent. On the contrary, I find C as well as D to be run-on. Suman, I did not understand your explanation for E. How does a 'noun phrase' come into picture here?

Although this structure is quite similar to the OG question, I don't think the options can be seen in the same way.

Also, I don't see any run-on sentences anywhere, not even in options C and D. "its" in these senteces refers back to water in the previous clause.

Now, while picking the correct option in this context, the only criteria remains the meaning each option conveys.

"an insufficient level" cannot cause anything by itself and hence, options ending with by (B,C and E) don't make any sense.

molecules can be prevented from being evaporated and henceIMO, D is the credited response for this question. I know it is the wordiest of choices, but conveys the intended meaning. Surprisingly, none of the posters' views mathches with mine.

vscid, can we have the OA and the source of this question?
Regards,
Harsha
