Mansour: We should both plan to change some of our investments from coal companies to less polluting energy companies. And here’s why. Consumers are increasingly demanding nonpolluting energy, and energy companies are increasingly supplying it.
Therese: I'm not sure we should do what you suggest. As demand for nonpolluting energy increases relative to supply, its price will increase, and then the more polluting energy will cost relatively less. Demand for the cheaper, dirtier energy forms will then increase, as will the stock values of the companies that produce them.
Therese responds to Mansour’s proposal by doing which of the following?
Advocating that consumers use less expensive forms of energy
Implying that not all uses of coal for energy are necessarily polluting
Disagreeing with Mansour’s claim that consumers are increasingly demanding nonpolluting energy
Suggesting that leaving their existing energy investments unchanged could be the better course
Providing a reason to doubt Mansour’s assumption that supply of nonpolluting energy will increase in line with demand
T：我不确定我们应该按照你的建议去做。 随着<对无污染能源的需求相对于供应的增加↑>，其价格将上涨，然后污染程度较高的能源成本相对较低。 对更便宜、更脏的能源形式的需求将会增加，生产它们的公司的股票价值也会增加。
说明 得出选项D的结论：建议【保持 现有能源投资investment 不变】更好
选项C的disagree（×）、选项E的doubt（×）、选项A属于脑补（×），选项B无关
cde三个选线
e不对，仔细读句意，是说doubt supply of nonpolluting energy will increase这个后者并没有doubt；
c，后者说了Demand for the cheaper, dirtier energy forms will then increase，但是没说Disagreeing that consumers are increasingly demanding nonpolluting energy；并不是非此即彼的关系，不要make extra assumption
所以T并没有反驳M的观点
T是补充了M的观点的后续
第二人为什么反对，因为改变了也不一定会赚钱/不会赚钱
D可以证明改了也不一定挣钱，和第二个人要表达的态度一致，
A只是原文逻辑链中的一环，不是全部（而且要说的更贴切一点，应该加个tend to）
E第二个人没有质疑第一个人的假设，第二个人的逻辑完全是另一回事
并没有doubt 第一个人说的话 Consumers are increasingly demanding nonpolluting energy, 第二个人是承认的 只不过 demanding 上升之后成本上升 又恢复到原来的状态了
句子理解：As demand for nonpolluting energy increases relative to supply, 随着对无污染能源的需求相对于供应的增加，意思是供应也增加、需求也增加，但需求的增加相对于供应的增加更大，更快。读懂这个句子就否掉了C/E。
