在学习毕出老师的cr书的时候,学习到方案推理的部分有一个问题,求大神解决一下~
Government in Shelby provides substantial subsidies to coal enterprises. Since the major revenue of coal enterprises derive both from selling the coal and from receiving government subsides, the welling price of the coal in Shelby is relatively low as compared to other countries. Therefore, both individuals and enterprises use coal to generate electricity. However, unlike combusting other fuel resources ,burning coals to generate power may produce many more pollutants such as sulfur dioxide. In order to reduce the pollution, the government plans to stop providing subsidies to coal enterprises.
Which of the following, if true ,raises the most serious doubt regarding the effectiveness of the government's plan to reduce the pollutants generated by burning coals?
B) In order to seize the market, coal enterprises in Shelby will still sell the coal in the same price as before even after the government stops providing subsidies.
E) Even if the government stops providing any subsidies, the price of domestic coals will still be significantly lower than that of imported coals.
对 这两个选项感觉很困惑!
如果是按照老师的思路,要找到方案的副作用/不可执行/达不到目的 这个思路来, 那这两个选项不都没办法达到目的吗?
对B, 就算政府这样做,煤炭的价格还是和之前一样,那大家还是会去烧很多煤炭来发电(题目里面有说因为煤炭便宜,所以大家烧煤炭发电),所以这个没达到目的
对E,就算政府这样所,本地的煤依然比进口的煤便宜。那这样,大家还是会烧煤发电啊,跟上面的思路不是一样么?拜托各位大神帮帮忙!?!!谢谢 |
