Although they are more temperamental and far more expensive than transistor-driven amplifiers, many audiophiles and audio professionals prefer the warmer, richer tones produced by vacuum-tube-driven amplifiers.

(A) many audiophiles and audio professionals prefer the warmer, richer tones produced by vacuum-tube-driven amplifiers
(B) many audiophiles and audio professionals think the warmer, richer tones produced by vacuum-tube-driven amplifiers make them preferable
(C) warmer, richer tones are produced by vacuum-tube-driven amplifiers and they are thus preferred by many audiophiles and audio professionals
(D) vacuum-tube-driven amplifiers are preferred because they produce warmer, richer tones by many audiophiles and audio professionals
(E) vacuum-tube-driven amplifiers are preferred by many audiophiles and audio professionals because these amplifiers produce warmer, richer tones

Although they are more temperamental and far more expensive than transistor-driven amplifiers, many audiophiles and audio professionals prefer the warmer, richer tones produced by vacuum-tube-driven amplifiers.

I answered A but the re-read the statement and thought it should be E.

My reasoning behind A was as follows -

Its active voice.
Correctly conveys the meaning - what most prefer
the sentence before comma is a complete clause and not a modifier hence the second statement need not start with Vacuum tube amplifier.

However we must have a noun to refer back for "They" in the first statement

E for me too.I think this is misplaced modifier question.

Look at the sentence-Although they are more temperamental and far more expensive than transistor-driven amplifiers, many audiophiles and audio professionals prefer the warmer, richer tones produced by vacuum-tube-driven amplifiers.

The modifier should modify the amplifiers and not audio proffesionals. Hence E is correct

Hi Samcot,

Can you give detail explanation for it?

E is the only answer choice that make "Gmat" sense. The first clause directly modifies another type of amplifier not an audiophiles.

Although they are more temperamental and far more expensive than transistor-driven amplifiers, [many audiophiles and audio professionals prefer the warmer, richer tones produced by vacuum-tube-driven amplifiers.]


many audiophiles and audio professionals prefer the warmer can't be temperamental and far more expensive than transistor-driven amplifiers . So they can't refer to "many audiophiles and audio professionals" instead it must be refer to vacuum-tube-driven amplifiers to make it more clear .
So A, B, c are out
D : meaning changed from original sentence
So E : is the correct answer


(A) many audi
ophiles and audio professionals prefer the warmer, richer tones produced by vacuum-tube-driven amplifiers
(B) many audiophiles and audio professionals think the warmer, richer tones produced by vacuum-tube-driven amplifiers make them preferable
(C) warmer, richer tones are produced by vacuum-tube-driven amplifiers and they are thus preferred by many audiophiles and audio professionals
(D) vacuum-tube-driven amplifiers are preferred because they produce warmer, richer tones by many audiophiles and audio professionals
(E) vacuum-tube-driven amplifiers are preferred by many audiophiles and audio professionals because these amplifiers produce warmer, richer tones
