“Pellucid” literally suggests translucence or clarity and, figuratively, extreme clearness of expression. In the sentence, the reference to first-year students signals accessibility; the explanation is easy to grasp. “Transparent” (D) is the closest synonym for both literal and figurative clarity. “Tentative” (A) means uncertain; an explanation can be tentative but still confusing, which doesn’t fit the praise implied. “Redundant” (B) signals unnecessary repetition, not clarity. “Provocative” (C) means stimulating or controversial, orthogonal to comprehensibility. Nelson–Denny Vocabulary tasks often rely on collocation and evaluative cues; words praising expository style (lucid, limpid, pellucid) commonly pair with teaching/clarification contexts. Build semantic families: clear (lucid, limpid, pellucid), obscure (opaque, turbid), uncertain (equivocal, tentative). During testing, confirm by substitution: “The explanation was transparent”—the sentence still reads naturally, validating the choice. Precision with high-register adjectives markedly improves comprehension speed on expository and argumentative passages.

The passage frames a policy trade-off: dark-sky rules benefit astronomy (less skyglow) and ecology (less disorientation), while business owners raise cost concerns. It then notes a mitigating detail—retrofits aligned with scheduled replacements reduce net costs. That balance among science, wildlife, and economics aligns with B. Option A is a straw man; the text doesn’t oppose lighting wholesale. Option C suggests science should trump safety—a claim not made. Option D contradicts the premise that birds migrate over cities. On Nelson–Denny title items, look for a concise synthesis incorporating stakeholders and outcomes. The stem provides three: astronomers, biologists, businesses. The correct title names the coordination challenge rather than an extreme stance. Watch for distractors that introduce absolute claims or deny facts present in the passage; succinct, balanced titles usually win when a paragraph presents benefits, concerns, and a moderating solution.
