请教逻辑

Current farm policy is institutionalized penalization of consumers. It increases food prices for middle- and low-income families and costs the taxpayer billions of dollars a year.

Which of the following statements, if true, would provide support for the author’s claims above?

I.     Farm subsidies amount to roughly $20 billion a year in federal payouts and $12 billion more in higher food prices.

II.    According to a study by the Department of Agriculture, each $1 of benefits provided to farmers for ethanol production costs consumers and taxpayers $4.

III.   The average full-time farmers have an average net worth of over $300,000.

(A) I only

(B) II only

(C) III only

(D) I and II only（D）

(E) I, II, and III

我认为正确答案为A

因为II中$1 benefits->$4 costs,但体现不了increase,而且也没有和过去比较,也许在该政策实施前,也是这个样子

D is the right answer.

(II) supports the author's argument.  The "$1 of benefits provided to farmers" is a diirect result of the "Current farm (subsidizing) policy".

我的推理

permise :It increases food prices for middle- and low-income families and costs the taxpayer billions of dollars a year

-->conclusion:Current farm policy is institutionalized penalization of consumers.

I:直接支持结论

II：直接支持结论

III：无关选项

不知我的理解对不对

II是对的,我认为,

想想,一刀能办的事情为什么要用4刀?中间肯定有环节,也许是贪污也许是浪费,总之就是POLICY的问题.

I: provide more details to fortify the evidence ("It increases food prices for middle- and low-income families and costs the taxpayer billions of dollars a year").

II: again, more details to fortify the evidence.
