问题 High levels of fertilizer and pesticides, needed when farmers try to produce high yield of the same crop year after year, pollute water supplies. Experts therefore urge farmers to diversify their crops and to rotate their plantings yearly. To receive governmental price-support benefits for a crop, farmers must have produced that same crop for the past several years. The statements above, if true, best support which of the following conclusions?
选项 A、The rules for governmental support of farm prices work against efforts to reduce water pollution.
B、The only solution to the problem of water pollution form fertilizers and pesticides is to take farmland out of production.
C、Farmers can continue to make a profit by rotating diverse crops, thus reducing costs for chemicals, but not by planting the same crop each year.
D、New farming techniques will be developed to make it possible for farmers to reduce the application of fertilizers and pesticides.
E、Governmental price supports for farm products are set at levels that are not high enough to allow farmers to get out of debt.
答案A
解析 农场主只有在他们年复一年地生产同一种作物时才能获得政府的价格补贴。那些希望获得这些价格补贴的农场主不可能减少对水的污染，因为他们不会听从专家们关于分散化和轮流种植的建议，因此，(A)是正确答案；由于专家们的建议显然是他们赞成的解决办法，而提出惟一的解决办法是别的什么[选项(B)]没有得到支持；该陈述既没有提到农场主的成本和收益，也没有提到耕作技术的发展(新概念)，因此不支持关于赢利前景[选项(C)]或将来耕作技术[选项(D)]的结论；因为没有给出关于价格补贴数量或农场主的债务的信息，选项(E)也没有得到支持。
