(B) for it to withhold from the public
(C) for withholding disclosure to the public of
(D) that enable them to withhold from public disclosure
(E) that they can withhold public disclosure of
Answer to Question 222
Choice A is best: enabling ... clearly modifies powers, it refers logically and grammatically to the Central
Intelligence Agency, and to withhold from the public is concisely and idiomatically phrased. In choices B and
C, the preposition for is used unidiomatically in place of the "-ing" modifier to introduce the phrase describing
powers. In choices C, D, and E, withholding)... disclosure is wordy and imprecise, since it is really the
identities that are to be withheld. The plural pronouns them in D and they in E do not agree with the singular
Agency, and that in E mistakenly introduces a new independent clause rather than a modifying phrase for
powers.
