The Earth’s inner core, a ball of solid iron, maybe rotated slower than by the outer Earth.


A. may be rotated slower than by the outer Earth

Meaning error. "may be rotated" implies some one else is performing the action of rotation INCORRECT

B. the outer Earth may rotate more slowly than it

Pronoun ambiguity error. Antecedent for "it" can be either inner core or ball. INCORRECT

C. it may rotate slower than the outer Earth

Subject-Verb missing error. No verb for the subject "Earth's inner core" INCORRECT

D. may rotate more slowly than the outer Earth

This options states as observation/fact using simple tense CORRECT

E. may be more slow at rotating than the outer Earth

Meaning error. "may be more slow at rotating" implies the Earth's inner core rotates something. INCORRECT

Hence option D

+1 for D

Just remove the modifier "a ball of solid iron" and combine the other phrases, option D provides the intended meaning and is grammatically correct.

The Earth’s inner core, may rotate more slowly than the outer Earth

+1 for D.

A. may be rotated slower than by the outer Earth

B. the outer Earth may rotate more slowly than it

C. it may rotate slower than the outer Earth

D. may rotate more slowly than the outer Earth --> Correct, rectifies pronoun error

E. may be more slow at rotating than the outer Earth

Hence, D.

IMO D
A: Earth's inner core cannot be rotated: incorrect meaning
B: this doesn't t make any sense. Also, we need a verb after the comma
C: it is ambiguous. Also, we need a verb after the comma
D: may is the verb after the comma.
E: wordy and awkward construction

KAPLAN OFFICIAL SOLUTION:



Correct Choice: (D)

This sentence sounds strange and does not make complete sense. It is unclear whether a comparison is being made between the rotation speed of the Earth’sinner and outer cores OR if the inner core is being rotated BY the outer core. Either way, there is a problem here. Since the meaning of the sentence must be clarified, we must go to the answers to see what the intended meaning is. We know immediately that we can eliminate choice (A), since the sentence is unclear as written.

Choice (D) creates a clear, concise sentence whose subject and verb and makes sense.

Choice (B) creates new errors. The pronoun “it” is too far from its antecedent, “the earth’s inner core; ”the construction is awkward; and there is no verb for what sounds like the primary subject of the sentence, “The Earth’s inner core, a ball of solid iron”.

Choice (C) unnecessarily places the pronoun “it” immediately after its antecedent.

Choice (E) is wordy and awkward.
