Jupiter & Saturn (A) Modifier; Parallelism (not only X but also Y); Comparison (so massive as; larger)
(B) Modifier; Parallelism (not only X but also Y)
(C) Sentence Structure; Parallelism (not only X but also Y)
(D) CORRECT
(E) Comparison (so massive as; larger)
First glanceThe first two answers start with the words
not only; the other three start with
Jupiter—and move not only later in the sentence. This signals a possible parallelism issue: what is the X portion of
not only X but also Y?
Issues(1) Modifier: The largest of all the planets, not only…The sentence begins with an opening modifier:
The largest of all the planets. After the comma, the sentence should name that planet.
Answers (A) and (B) do not place the noun
Jupiter immediately after the comma. Further,
Jupiter is actually separated from the modifier by the verb,
is. Noun modifiers should not be separated from the modifier by a verb. Eliminate answers (A) and (B).
(2) Parallelism: not only X but also YSentence Structure
The idiom
not only X but also Y requires parallelism between the X and Y elements. The Y element is a verb,
possesses, and it is not underlined, so the X element must also be a verb.
(A) not only
is Jupiter…but also
possesses(B) not only
is Jupiter…but also
possesses(C) Jupiter, not only
three times…but also
possesses(D) Jupiter not only
is three times…but also
possesses(E) Jupiter is not only
three times…but also
possessesIn (C) and (E), the X element (
three times) is not a verb. Eliminate these two answers.
One more level of parallelism is at issue. The root phrase (the portion before the parallelism begins) must make a grammatical sentence when paired with either X or Y.
When you have a closed marker, such as
not only X but also Y, the root phrase always appears immediately before the first part of the closed marker— in this case, prior to not only. Anything after
not only (and before
but also) is part of the X element. Answers (A) and (B), though, both place
Jupiter inside the X element, rather than prior to not only as part of the root phrase. Pair the root phrase with the X and Y elements in turn to confirm that they result in ungrammatical sentences:
The largest of all the planets…
X: … is Jupiter three times so massive as Saturn (incorrect)
Y: … possesses four of the largest satellites (correct)
X: … is Jupiter three times as massive as Saturn (incorrect)
Y: … possesses four of the largest satellites (correct)
In both cases, pairing the root phrase (
The largest of all the planets) with the X element results in an ungrammatical sentence. Eliminate (A) and (B).
(Note: if answer (E) hadn’t already been eliminated, you could also eliminate it for this same reason.
Jupiter is possesses four of the largest satellites is not grammatical.)
(3) Comparison: so massive as; largerThe phrasing
X is so massive as Y is not the correct comparison idiom. It should say
as massive as.
In addition,
larger is used to compare
only two items. If there are three or more items in the group, use
largest. While you may already know that there are more than two planets in the solar system, note that you don’t actually need to know this: the sentence begins the
largest of all the planets, indicating that there are at least three planets. So, when talking about Saturn, call it the
next largest. Eliminate answers (A) and (E) for using
larger.
The Correct AnswerCorrect answer (D) constructs the parallel format properly (
Jupiter not only is three times…but also possesses…) and uses the correct comparison terms
as massive as and
largest.
