Difficulty:

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.

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

Looks like a straightforward (A) here. There is an inherent contradiction in the needs of the farmers and the pollution levels caused by pesticides.

I have chosen A for this question:

The passage has 2 paragraphs. The first states the need to diversify crops to reduce water pollution and the second states the rules for government support. The two statements clash because in order to receive government support, the farmers must produce the same crop for several years, but by doing so, there is water pollution.

A. This statement is a combination of both paragraphs and is the correct answer.

B. We don't know that "the only solution..." is true. It could be that there are many different solutions, so this may or may not be true. Therefore, it is incorrect.

C. How can we be sure that farmers will still be making a profit? It could be that the government support is the only thing that allows farmers to profit and without it, they are losing money even if we include the reduction in chemical costs. Therefore, this statement cannot be proven from the passage and is incorrect.

D. This statement brings in outside information - this is incorrect.

E. Again, this statement cannot be proven from the passage. It may or may not be true, therefore this statement is incorrect.

How can the solution be A!!?

The first paragraph says that water pollution occurs when farmers try to produce 'high' yields of crop year after year.
In second paragraph, though the rules for governmental support says farmer must have produced the same crop for several years, they never say farmer must have produced them in high yields!
Putting the two together, the governmental support rules do not work against efforts to reduce water pollution. A farmer can produce same crop, year after year, in normal yields and can get the support benefit without increasing any pollution. Option 'A' doesnt seem correct.

Thanks.

Interesting point! However, we also need to consider the second sentence in the context of the first. Let me rephrase the argument:

Experts urge farmers to diversify their crops and to rotate their plantings yearly because some farmers pollute the water when they plant the same crop every year. To receive governmental price-support benefits for a crop, farmers must have produced that same crop for the past several years.

See how I've combined two sentences into one here? Now it's clear why (A) is correct.

The trick I used, though, is that I didn't assume that all farmers try and produce high yield crops. And in fact, we don't need to assume that to arrive at conclusion (A). We just need to assume that some farmers try and produce high yield crops, which I would consider safe even if unstated. The "high yield" stipulation is, therefore, just a distraction.

Thanks Ryan. The modified argument makes complete sense.
My exam is now less than 10 days away and I am still struggling a lot with inference questions. Distraction, like the one above, is the last thing I will need during the exam.

The statements above, if true, best support which of the following conclusions?

(Al The rules for governmental support of farm prices work against efforts to reduce water pollution.
(B) The only solution to the problemof 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 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

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

Please note that I have done a little modification in the answer choice C, in this case please provide your opinion can we consider C as correct answer.

Reasoning:
One may thing that farmers could have more than one crop and they can rotate the diversified "set of crops" that they have and in turn reduce fertiliser/pesticides. Because it is not mentioned that a farmer can only procure one crop/field, it may be possible that he may have a large area and where multiple crops caould be grown. By doing this they can still continue to grow a crop for more than 05 years and earn the government incentive too.

Chose A, but was confused how can government policies not support "efforts against water pollution". But, for MBT just trust what is written and do not bring outside knowledge or logical thinking.
