Economist: The price of tap water in our region should be raised drastically. Supplies in local freshwater reservoirs have been declining for years because water is being used faster than it can be replenished. Since the price of tap water has been low, few users have bothered to adopt even easy conservation measures.
The two sections in boldface play which of the following roles in the economist’s argument?
The first is a conclusion for which support is provided, and which in turn supports the main conclusion; the second is the main conclusion.
The first is an observation for which the second provides the explanation; the second is the main conclusion but not the only conclusion.
The first is a premise supporting the argument’s main conclusion; so is the second.
The first is the only conclusion; the second provides an explanation for the first.
The first is the main conclusion; the second is a conclusion for which support is provided, and which in turn supports the first.
情景：自来水的价格该涨啦。因为消耗比补充的更多，所以当地自来水供给正在下降。因为自来水价太低，所以很少有人想采取就算很简单的节水方式。
推理：略。
选题方式：本题中的第一个黑体字和第二个黑体字都在给自来水应涨价提供理由。
选项分析：
A选项：第一个黑体字是一个被支持的结论，并且它支持主结论；第二个黑体字是主结论。
B选项：第一个黑体字是一个第二个黑体字提供了解释的观察；第二个是主结论但不是唯一的结论。
C选项：Correct. 第一个黑体字是支持文章主结论的前提；第二个黑体字也是。
D选项：第一个黑体字是唯一的结论；第二个黑体字给第一个提供了解释。
E选项：第一个黑体字是主结论；第二个是一个被支持的并且支持第一个黑体字的结论。
这道题对我来说太难了：两句黑体字分别是两个原因状语从句的主句，而其均无证据进一步支持（这很重要），所以都是事实观察，作为前提；
分析很到位
