通过对旧GRE考题和两次改革后的样题比较，我们可以很清楚的发现，新GRE阅读的文字内容，复杂程度有所降低。而逻辑复杂程度持续增加。这反映了ETS对于影响研究生阶段学术成功的基本能力的更为深入的把握。实际上GRE考试阅读文章难度，略高于北美研究生所需阅读文章难度，采用这种形式的文章，主要目的是模拟较高难度下研究生阅读的情景，以期能够测出学生的潜力，这个思路有点类似于我们常说的压力面试。
Policymakers must confront the dilemma that fossil fuels continue to be an indispensable source of energy even though burning them produces atmospheric accumulations of carbon dioxide that increase the likelihood of potentially disastrous global climate change. Currently, technology that would capture carbon dioxide emitted by power plants and sequester it harmlessly underground or undersea instead of releasing it into the atmosphere might double the cost of generating electricity. But because sequestration does not affect the cost of electricity transmission and distribution, delivered prices will rise less, by no more than 50 percent. Research into better technologies for capturing carbon dioxide will undoubtedly lead to lowered costs.
1. The passage implies which of the following about the current cost of generating electricity?
It is higher than it would be if better technologies for capturing carbon dioxide were available.
It is somewhat less than the cost of electricity transmission and distribution.
