Threat is imposed by el mg field. Hence A B D are out.
E conveys what sentence intends to say but if we look at the construction "threat posed by electromagnetic fields generated by household appliances". This too much use of 'by' makes it a bad boy....and hence I eliminated it. So acc to me answer is C

Hi mates,

IMO C

A out: "posing" is not correct
B out: "that" is not needed
D out: the inversion of subject-verb (any threat-poses) is not needed her
E out: akward

OA and Source?

Cheers

C is correct.

(A) of electromagnetic fields generated by household appliances posing any health threat - WRONG because although + clause, not noun phrase.
(B) of electromagnetic fields generated by household appliances that pose any threat to health - WRONG because "that" modifies "appliances", --> change meaning
(C) that electromagnetic fields generated by household appliances pose any threat to health - CORRECT
(D) that poses any threat to health from electromagnetic fields generated by household appliances - WRONG, change meaning, because "that" modifies exists --> doesn't make sense.
(E) for any health threat posed by electromagnetic fields generated by household appliances - WRONG, although + clause, not noun phrase.

Although + clause ==> A, E are out.
B is out because of wrong modifier "....household appliances that pose........"
D is out because of wrong modifier "no proof yet exist that poses.............."
C is correct.

The reasoning is wrong. "Although+clause" is valid. e.g.,
Although I was sick, I went to school..... correct

A and E cannot be eliminated because of the reason stated by pqhai. There is no problem with a subordinate clause starting with "although".

Option A implies that there is no proof of electromagnetic force ( i.e. there is no proof that electromagnetic force exists). The part "generated by household appliances posing any health threat" is a modifier of "electromagnetic force ". However the intended meaning is that no proof exists of the fact the EMF poses threat - this meaning is not conveyed in Option A.

Similarly option E implies that there is no proof of health threat ( i.e. there is no proof that health threat exists). The part "posed by electromagnetic fields generated by household appliances" is a modifier of "health threat ".

Although no proof yet exists of electromagnetic fields generated by household appliances posing any health threat, mounting scientific evidence has convinced many experts that there is cause for concern.
Quote:
(A) of electromagnetic fields generated by household appliances posing any health threat

Ahh, we have (of)PREP+NOUN+VERB-ing (of + electromagnetic fields + posing) construction, which is mostly considered to be wrong in GMAT(As quoted by Ron Purewal). Because here Action of the sentence is the intended object of the preposition.In that case meaning of the sentence will be distorted. So we can safely eliminate option A
Quote:
(B) of electromagnetic fields generated by household appliances that pose any threat to health

Is household appliances that pose any threat to health? No, so we can eliminate this option.
Quote:
(C) that electromagnetic fields generated by household appliances pose any threat to health

Sounds good and technically correct. So let us hold this option.
Quote:
(D) that poses any threat to health from electromagnetic fields generated by household appliances

Is proof poses threat to health? Eliminate this.
Quote:
(E) for any health threat posed by electromagnetic fields generated by household appliances

Here the idiomatic usage is wrong. Correct idiom is proof of something or proof that+clause. There is no such things as proof for something.

Dear AnthonyRitz DmitryFarber GMATGuruNY AjiteshArun GMATRockstar IanStewart MartyTargetTestPrep,

Is proof FOR in E. wrong?

I've found an example of proof FOR here https://www.lexico.com/definition/proof
Quote:
‘this is not a proof for the existence of God’

However, according to https://www.beatthegmat.com/gprep-sc-4-t278451.html,
Quote:
E: Although no proof yet exists for any health threat
Here, for any health threat seems to refer to proof, but proof for is unidiomatic.
The correct idiom is X is proof OF Y.
Eliminate E.

Please help :)

It's not idiomatic. Non-idiomatic phrases aren't technically 'wrong' a lot of the time (grammatically they're often fine) and there can be rare cases where you'd want to use them, if you're using words in non-idiomatic ways. "Proof for" is not the main reason E is a bad answer here.

Dear IanStewart,

Could you share how to reject choice E. on solid grounds?

One of the most useful things you can learn, when studying wrong answers to SC questions, is how to recognize bad writing. Answer E here is terrible writing - whenever you string a lot of modifiers together as E does, it becomes unclear what goes with what. Sometimes answers that do that will still be correct (if a sentence is expressing an especially complicated idea) but they're usually wrong, because usually it's possible to express things with greater clarity. You can see the problem with the construction in E by comparing these two sentences:

"Tigers raised in zoos released into the wild stand little chance of survival."
"Tigers raised in zoos run by our state stand little chance of survival."

The sentences have the same structure, but the modifiers (if you interpret the sentences sensibly) are connected differently in each. In the first sentence, the intended meaning is that the tigers are "released into the wild". In the second sentence, the intended meaning is that the zoos are "run by the state". You could just as easily interpret the first sentence to mean that the zoos are released into the wild, and the second to mean that the tigers are run by the state.

E has the same problem. Is the threat generated by appliances, or is the radiation? Even more important than that though is that E is just bad writing, and if you see a lot of modifiers strung together, you should look for a different answer that makes connections between modifiers and their objects unambiguous. Only pick the potentially unclear answer if you find no better option.
