Ex that dont follow Idioms or I dont understand Idioms?

by lav » Thu Mar 26, 2009 4:27 am
Hi
I am not sure if the examples below are wrong OR my understanding of Idioms ...
27). Displays of the aurora borealis, or "northern lights," can heat the atmosphere over the arctic enough to affect the trajectories of ballistic missiles, induce electric currents that can cause blackouts in some areas and corrosion in north-south pipelines.

(A) to affect the trajectories of ballistic missiles, induce
(B) that the trajectories of ballistic missiles are affected, induce
(C) that it affects the trajectories of ballistic missiles, induces
(D) that the trajectories of ballistic missiles are affected and induces
(E) to affect the trajectories of ballistic missiles and induce
I read that "enough that" is idiomatic and but OA is E
28). The golden crab of the Gulf of Mexico has not been fished commercially in great numbers, primarily on account of living at great depths-- 2,500 to 3,000 feet down.

(A) on account of living
(B) on account of their living
(C) because it lives
(D) because of living
(E) being they live
OA is C In explaination it is said A, B, D - the phrases "on account of" and "because of" are unidiomatic; "because", which appears in C and E, is preferable
BUt in ALL BOOKS they have topic "due to" vs "because of" So i concluded that "because of" is idiom

Pls advice !!

“enough that” and “enough to” both are correct. “that” introduces a subordinate clause, so “enough that” should be followed by a subordinate clause. In “enough to,” “enough” is acting as an adverb, so “enough to” should be followed by a noun.

enough that is unidiomatic.

but A to D are wrong also for reasons other than the idiom itself

A. we need a "and" betweent the two effects of heating the atmosphere

B. not parallel. uses passive and active

C. we need a "and" betweent the two effects of heating the atmosphere

D. not parallel. uses passive and active voice to describe the two effects of heating

E. is correct as it maintains parallelism in the two effects and also it uses "and" to describe the two effects.
28). The golden crab of the Gulf of Mexico has not been fished commercially in great numbers, primarily on account of living at great depths-- 2,500 to 3,000 feet down.

(A) on account of living
(B) on account of their living
(C) because it lives
(D) because of living
(E) being they live
B and E out because of subject verb agreement error.

A and D do not have a pronoun to refer back to the "golden crab".

C has a pronoun to refer back to the crab, also it makes the reasoning clear. 'because' is normally followed by clause (subject+verb). so C makes the cut

“Their” is straight wrong in B. However, except awkwardness, I can’t think of any rule behind knocking out A and D. “on account of” and “because of” both are idiomatic – at least google shows so. However, they might not be fitting in this context. “Because of” is used to give reasons for some event. However, in this case we are talking about a fact, so “It (The golden crab) lives at …feet down” makes more sense to me.

I hope, someone will have a better explanation.

@Scoobydooby
Is "enough that" always wrong? Or is it context dependent? Is the following sentence wrong: "Today, I have worked enough that I need not have to come on weekends."

karmayogi, yes tricky indeed. it might be context dependent after all. am confused

lets hope there are other errors in the choices apart from "enough that"and "enough to" :)

"enough to" was better in the sentence as the infinitive "to" describes the effects/purpose better

Aurora Borealis

by rah_pandey » Wed Jun 03, 2009 10:38 pm
Can somebody let me know in "Aurora Borealis" question why is option E correct. The GMAT prep s/w says we need to have a conjunction between the two effects produced by Aurora Borealis. I think there are 3 effects
1. to affect trajectories
2. induce electric currents
3. corrosion in north south pipelines

Why do we need conjunction "and" between 1 and 2. Am i missing something here

Yes....at first, I understood that as 3 effects too. But if you read the sentence carefully, displays of the aurora borealis causes only 2 effects: affect trajectories and induce electric currents. It is the electric currents that cause blackouts and corrosion in north-south pipelines. Critiques, please correct me if I'm wrong.

That still leaves me with another question....how can you have 2 "ands" in a single sentence???Isn't it grammatically wrong???
