That's a good question.The author says that the town's frequent water emergencies could be avoided if they would give people incentive to conserve. The author says that conservation is discouraged by current policies, which charge a flat rate up to a certain point; beyond that point, people are charged a substantial, per-liter rate (in that case, if the threshold were very high, people could use as much as they wanted without worrying about extra fees).
The question asks for the answer choice that most strengthens the author's argument. Answer choice (C) provides that the threshold is higher than most people's requirements. This strengthens the author's argument that currently, there is no incentive to conserve—people can use as much as they need, or more, without passing the threshold and getting charged extra fees. (if, on the other hand, the threshold were below the level of most people's needs, then the substantial additional fees would provide an incentive to start conserving water).
Tough question--please let me know whether this is clear--thanks!
