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?

(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 from 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.（A）

(E) Governmental price supports for farm products are set at levels that are not high enough to allow farmers to get out of debt.


why not choose C？

我跟你错的一样，后来仔细看了题干。

两个论点：

1、专家敦促农民多样化种植作物

2、农民单一化种植，以获得政府资助

问以上两个观点支持下面哪个推论？

当然是A，说政府的政策阻碍了减少水污染的努力，即against专家的论点。

C说的是农民可以通过多样化经营提高理论，以及bla, bla，重复了论点1，专家的话，那么论点2就不要了吗？？
