Perhaps nowhere else in America can one see a greater span of architectural history than on Ivy League campuses with their blend of the classic and the contemporary, each of the campus buildings a monument to the era in which it was built.
(A) each of the campus buildings a monument to the era in which it was
(B) all of the campus buildings a monument to the era in which they were
(C) all of the campus buildings a monument to the era in which it was
(D) every campus building a monument to the era in which they were
(E) each of the campus buildings a monument to the era in which they were
Choice A: Option A maintains proper subject-verb agreement throughout the sentence and conveys the intended meaning of the sentence. Thus, Option A is correct.
Choice B: In Option B, we see a meaning error. Through the phrase, "all of the campus buildings a monument", this answer choice implies that all of the campus buildings across the Ivy League campuses represent a singular monument. This implication does not make logical sense. Thus, Option B is incorrect.
Choice C: In Option C, the pronoun "all" is used alongside the noun "campus buildings"; this means that "all" is singular in this sentence. Therefore, the use of the singular pronoun "it" is incorrect. Thus, Option C is incorrect.
Choice D: In Option D, we see a subject-verb disagreement between "every" and "were". Thus, Option D is incorrect.
Choice E: In Option E, we see a subject-verb disagreement between "each" and "were". Thus, Option E is incorrect.
Hence, A is the best answer choice.It should be noted here that "all" is one of the pronouns that can be singular or plural, depending on the context. These pronouns, which also include "some", "none", "any", and "many", are usually used with the conjunction "of" and will be singular or plural, depending on the form of the noun or pronoun that follows "of".
