[求助]prep2上的逻辑

The cotton farms of Country Q became so productive that the market could not absorb all that they produced.  Consequently, cotton prices fell.  The government tried to boost cotton prices by offering farmers who took 25 percent of their cotton acreage out of production direct support payments up to a specified maximum per farm.

The government's program, if successful, will not be a net burden on the budget.  Which of the following, if true, is the best basis for an explanation of how this could be so?

(A) Depressed cotton prices meant operating losses for cotton farms, and the government lost revenue from taxes on farm profits.

(B) Cotton production in several countries other than Q declined slightly the year that the support-payment program went into effect in Q.

(C) The first year that the support-payment program was in effect, cotton acreage in Q was 5% below its level in the base year for the program.

(D) The specified maximum per farm meant that for very large cotton farms the support payments werl4e less per acre for those acres that were withdrawn from production than they were for smaller farms.

(E) Farmers who wished to qualify for support payments could not use the cotton acreage that was withdrawn from production to grow any other crop.

answer：A   

其实主要是黄色背影那句话没有看懂。 谢谢

黄线部分主干是by offering farmers direct support payments

意思是说按照每亩最大产值直接补助农民，条件是他们缩减25%的种植面积

本题的关键还是The government's program, if successful, will not be a net burden on the budget。

A说明了政府损失的税收可能高于政府的补助，反之补助有助于恢复税收，所以will not be a net burden on the budget.
