Because the city's files covered only the years 1934 through
2002, so the potential buyers were unable to determine the year of originally construction.
(A) 2002, so the potential buyers were unable to determine the year of originally
(B) 2002, and the potential buyers were unable to determine the year of originally
(C) 2002, the potential buyers were unable to determine the year of original
(D) 2002, therefore the potential buyers were unable to determine the year of originally
(E) 2002; therefore, the potential buyers were unable to determine the year of original
KAPLAN OFFICIAL EXPLANATION:
C
The first problem here is that the use of so to connect the second part of the sentence to the first is unnecessary and incorrect. Since the first part of the sentence (
Because...2002,) is a dependent clause indicating causation, no further transition is needed between it and the main clause, beginning with
the potential buyers. The second problem is that
originally is an adverb, which cannot be used to modify the noun construction; it must become the adjective
original. Only (C) corrects both problems.
(B) needlessly replaces so with the conjunction
and, and retains
originally. In (D) and (E),
therefore is redundant since the sentence already begins with the word
Because, which indicates the causation.
