Situation: Geologic evidence strongly suggests that at some point in the next decade, the La Maria volcano will erupt. News of the potential eruption is likely to cause tourists to stay away from destinations in La Maria County.
Goal: The La Maria Chamber of Commerce wishes to maintain the present high rate of tourism in La Maria County.
Proposal for consideration: Develop an advertising campaign that emphasizes the safety of La Maria destinations in the case of a volcano eruption.
In light of the situation, which of the following, if true, most strongly argues that adopting the proposal would be an ineffective way of achieving the goal?
(A) Tourists who visit La Maria County rate safety as one of their top priorities in choosing a vacation destination.
(B) All over the world, there are active volcanoes near areas whose economies depend on tourism.
(C) Very few visitors to La Maria County participate in volcano-related activities such as camping and hiking.
(D) Most potential vacationers to La Maria County are not aware that the volcano is active, and would discover that it is through advertisements that emphasize the area's safety.
(E) Compared to tourist destinations that are not near active volcanoes, La Maria County is an inexpensive place for a family to vacation.
OFFICIAL EXPLANATION
D
"Strongly argues" makes this sound like a strengthen question, but the word "ineffective" tells you we're looking to weaken the proposal. Since the passage is broken up like this, it's worth trying to paraphrase the "argument". Basically: "The volcano may erupt, which might make tourists skittish, but we want to keep tourists coming, so we should advertise that the area is still safe".
Choice (A) strengthens the argument by providing a solid reason for the advertisements. (B) is irrelevant, as there is no mention on whether tourists visit those areas when volcanoes are likely to erupt, and what prompts them to do so. (C) is also irrelevant, as we don't know whether the safety issues extend to tourists who are not on the mountain itself.
Choice (D) explains why advertising may not be a good idea. If they aren't aware of the safety issues, they won't stay away; if the advertisements make them aware of the safety issues, they may still come, but they certainly wouldn't be more likely to do so. (E) is irrelevant, as the argument has nothing to do with cost. Choice (D) is correct.
