The original sentence contains a faulty comparison: it compares the military of the
United States to Japan, rather than to Japan’s military.
(A) This choice is incorrect as it repeats the original sentence.
(B) This choice repeats the comparison error in the original sentence. Additionally,
this choice creates a pronoun error by using the plural pronoun “their” to refer to the
singular “United States.”
(C) This choice corrects the comparison error by comparing the military of the United
States to “that” of Japan. However, this choice includes a pronoun error by using the
plural pronoun “their” to refer to the singular “United States.”
(D) CORRECT. This choice correctly compares the military of the United States to
“Japan’s”; although “military” is not explicitly stated, the possessive form implies that it
refers to Japan’s military. Additionally, the singular pronoun “its” correctly refers to the
singular “United States.”
(E) This choice unnecessarily shifts to the present perfect tense “has been
larger,” which is not parallel with the present tense verb “shoulders” in the main
clause of the sentence. Furthermore, a military is a singular entity, whereas “those of
Japan” incorrectly refer to something plural.
