OE


The detour road sign “but” in the first sentence indicates that there is a contrast between how the Dewey Decimal System is perceived in light of new technology and the fact that it “continues to be a valuable organizational tool.” You can predict that the Dewey Decimal System may seem “outdated.” This prediction matches (B) archaic, which means “old-fashioned.” Eliminate (A) abstruse, which means “difficult to understand,” and (C) misguided, which means “foolish,” as neither is supported by the context clues. For the second blank, the context clues “continue” and “in perpetuity” (meaning “forever”) indicate that the accumulation of knowledge is a pursuit that never ends. You can predict the phrase “an infinite” to complete the sentence. Choice (F) an inexhaustible means “an endless” and is correct. Eliminate (D) a vacuous, as vacuous means “foolish,” and (E) an illuminating, as illuminating means “enlightening,” since neither meaning is supported by the context clues.
