23. The correct answer is (C). The argument relies on the unstated assumption that the
funds used to maintain the roads would be available for the education program should
the ordinance be repealed. Choice (C) provides evidence that this assumption is a
reasonable one; if the roads are of no other practical use, then there would be no need to
continue to spend county funds to maintain them. Choice (D) does admittedly lend some
measure of support to the argument. Common sense tells us that the education program
would be effective only if the group of individuals whom it is designed to benefit actually
benefit from it. However, we are not informed whether the entire population is in fact
susceptible to Smith’s Disease. Without this additional information, it is impossible to
assess the degree to which choice (D) strengthens the argument.
