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?
T的point没有说M的推断（nonpolluting的demand更多）不对，而是提出了另一个观点（这种趋势会导致more polluting energy的公司demand增多，从而反应在股价上），所以其实就维持以前的投资策略挺好。
The point of Therese's response is that since the stock prices of coal companies and other companies producing dirty energy will likely increase, investments in these stocks will increase in value. This provides a financial reason not to do what Mansour advocates.
