If one string is half the length of another, then the pitch that is produced by plucking the shorter string is one octave higher than by plucking the longer string.
A) the pitch that is produced by plucking the shorter string is one octave higher than by plucking the longer string
B) if one plucks the shorter string, the pitch produced is higher by one octave than is the pitch produced if one plucks the longer string
C) plucking the shorter string produces an octave higher pitch than the longer string
D) if you pluck the shorter string, you produce a pitch higher by one octave than if the longer string is plucked
E) the pitch produced by plucking the shorter string is one octave higher than that produced by plucking the longer string

OFFICIAL EXPLANATION
THE PROMPT
THE OPTIONS
On the right hand side of than we need something along the lines of:
The pitch [that is] produced by ABC is higher than [is?] [the pitch produced/THAT produced] by XYZ
• the right side of the comparison marker than does not match the left side.
-- on the right hand side of than, we need to refer somehow to "the pitch that is produced" [by plucking the longer string]
-- in this case, the pitch [that is produced] is higher than "by plucking the longer string" (a prepositional phrase)
-- we can elide quite a bit, but we cannot get rid of all reference to some kind of noun near "longer string" that would match "pitch."
Eliminate A
• Be wary of the pronoun "one." [It means "generic person."] GMAC rarely uses it (although in OG 2020 one question tests one/you).
• The sentence is grammatical — horribly written, but grammatical.
KEEP verrrryyy tentatively and hope that another answer is better.
Eliminate C
• not parallel and needlessly wordy. We need
-- "If you pluck the shorter stringer, you produce a pitch one octave higher than if you pluck the longer string."
Shifting voice is not okay; the switch to passive voice ruins parallelism
Eliminate D
• parallelism is good: the sound produced by plucking ABC is higher than [the pitch] produced by plucking XYZ.
Never mind about option B.
OPtion E is much better.
The best answer is E.
COMMENTS
Wow. Usually comparison questions create scary stats. These stats are good.
And so are these answers.
Praveenksinha and shameekv1989 , you've both done an excellent job.
Nice work! Kudos.

Eliminate A
Quote:
• Wow, this sentence is horrible. Passive language creates too many words, many of which do not need to be repeated. Very awkward. Easy to see why we need ellipsis.
• Be wary of the pronoun "one." [It means "generic person."] GMAC rarely uses it (although in OG 2020 one question tests one/you).
• The sentence is grammatical — horribly written, but grammatical.
KEEP verrrryyy tentatively and hope that another answer is better.
Quote:
• the pitch is not an octave higher than the longer string. We can't compare a sound with a string. The string isn't a sound.
Eliminate C
Quote:
• don't shift from active voice "if you pluck the shorter string" to passive voice "if the longer string is plucked" in one sentence
• not parallel and needlessly wordy. We need
-- "If you pluck the shorter stringer, you produce a pitch one octave higher than if you pluck the longer string."
Shifting voice is not okay; the switch to passive voice ruins parallelism
Eliminate D
Quote:
• bingo. The highlighted that is shorthand for "the pitch."
• parallelism is good: the sound produced by plucking ABC is higher than [the pitch] produced by plucking XYZ.
Never mind about option B.
OPtion E is much better.
The best answer is E.

If one string is half the length of another, then the pitch that is produced by plucking the shorter string is one octave higher than by plucking the longer string.
the pitch that is produced by plucking the shorter string is one octave higher than [the pitch that is produced] by plucking the longer string
The only difference between A and E seems to be "the pitch that is produced" vs "the pitch produced" which mean same. The Latter seems to be more efficient than the former in writing the sentence. Moreover, with the addition of "that" makes it a bit more clear of what needs to be there against A where the ellipsis needs to be identified and then see if it works.
Hence I would go with E.

Seems correct gramatically
the pitch that is produced by plucking the shorter string is one octave higher than [the pitch that is produced] by plucking the longer string
Quote:
unnecessary uses of "if" - "If A then if B, C than is D" against "if A then B, C than D"
Quote:
we need an helping verb after than for this to stand, otherwise the comparison would be between the pitch produced and longer string
Quote:
"you produce a pitch higher" - "what is the point of plucking a string and producing a sound from your mouth"; pitch is produced as a result of plucking not that we intentionally produce a pitch
Quote:
Seems gramatically correct as well. the pitch produced by plucking the shorter string is one octave higher than that (the pitch) produced by plucking the longer string
