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’s inner 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.
