High levels of fertilizer and pesticides, needed when farmers try to produce high yields 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 statement 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.
E: Governmental price supports for farm products are set at levels that are not high enough to allow farmers to get out of debt.

The correct answer is (A). Can somebody explain why (D) is wrong or not better than (A)? Thank you.

how can you deduce D ? the conclusion bases on the evidence. in the argument there is no hint that new farming techniques will be developed. in fact there are two kinds of evidence that support the conclusion. a important rule is that you sticky close to the argument and that you dont infer or deduce too much.

Hello Christoph,
Thank you for your response. I now see why (A) is correct, but let me respond to you the reason why I initially picked up (D).

In order to continue to receive the price-support benefits from the government, you need to keep producing the same crop. However, you will then conflict the water pollution.

Therefore, in order to achive both objectives(receive the governmental price-support & deal with less water pollution), the conclusion I took was to develop new farming techniques which is Choice (D).

What do you think of? Thank you for your kind response.

but...A also assumes that "several years" would mean..several past continuous years!..but is probably the best of the lot!

(I picked C..but then, there is nothing mentioned abt. revenues etc...as given in the OG explanation..)

A: The rules for governmental support of farm prices work against efforts to reduce water pollution.
Correctly concludes based on info given

B: The only solution to the problem of water pollution from fertilizers and pesticides is to take farmland out of production.

only solution is too extreme and is not mentioned in the arguement

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.

Infact farmers profit can be reduced because they can no longer plant to get "high yields of the same crop". Hence this is wrong

D: New farming techniques will be developed to make it possible for farmers to reduce the application of fertilizers and pesticides.
- Just a wishful thinking. Wishful thinkings are not allowed in CR

E: Governmental price supports for farm products are set at levels that are not high enough to allow farmers to get out of debt.
There is no mention of farmers debt anywhere. Hence out of context
