1.Escalating worldwide demand for corn has led to a sharp increase in the market price of corn, and corn prices are likely to remain high. Corn is extensive used as feed for livestock, and because profit margins are tight in the livestock business, many farmers are expected to leave the business. With fewer suppliers, meat prices will surely rise. Nonetheless, observers expect an immediate short-term decrease in meat prices.

Which of the following, if true, most helps to justify the observers’ expectation?

A. The increase in corn prices is due more to a decline in the supply of corn than to a growth in demand for it.
B. Generally, farmers who are squeezed out of the livestock business send their livestock to market much earlier than they otherwise would.
C. Some people who ate meat regularly in the past are converting to diets that include little or no meat.
D. As meat prices rise, the number of livestock producers is likely to rise again.
E. Livestock producers who stay in the business will start using feed other than corn more extensively than they did in the past.
此题我已经排除了C,D,E。A说的是玉米价格增长的原因，为什么不选A？B的比较根本就没说啊，为什么要选B? 是我把句子理解错了吗？
2. Journalist: Well-known businessman Arnold Bergeron has long been popular in the state, and he has often talked about running for governor, but he has never run. However, we have just learned that Bergeron has fulfilled the financial disclosure requirement for candidacy by submitting a detailed list of his current financial holdings to the election commission. So, it is very likely that Bergeron will be a candidate for governor this year.

The answer to which of the following questions would be most useful in evaluating the journalist’s argument?

A. Has anybody else who has fulfilled the financial disclosure requirement for the upcoming election reported greater financial holdings than Bergeron?
B. Is submitting a list of holdings the only way to fulfill the election commission’s financial disclosure requirements?
C. Did the information recently obtained by the journalists come directly from the election commission?
D. Have Bergeron’s financial holdings increased in value in recent years?不沾
E. Had Bergeron also fulfilled the financial disclosure requirements for candidacy before any previous gubernatorial elections?
E是说以前的选举，没有提到啊，B为什么不对？答案是E.
希望大家给个详细的解释

这种题要分析整体的逻辑关系而不是局部的, 而且要考虑经济学常识.

1. 题目已经说了, 因为玉米价格上涨, 很多农民会退出养殖业, 正常来说会导致牛肉价格上升(因为供应量少了). 但是很多人认为会有短期的牛肉价格上涨 - 如何证实这个貌似矛盾的结论?

答案是B, 因为B解释说哪些退出养殖业的农民会大大提早卖掉他们的牲畜 - 这样市场上就会出现短期的过量供应, 所以价格会短期下跌.
A反而只解释玉米价格上涨的原因, 还是没有解释为什么牛肉价格会短期下跌而不是上涨.

2. E对, 因为原文说这个人以前都没有角逐竞选, 而这次递交了财产申报 - 必须要证明以前州长竞选的时候他没进行财产申报才使逻辑成立 ( 不然的话, 他可以只是递交财产申报却仍然不参加最终角逐).
B不是很关键:不管有几种申报方法, 只要申报了就没有区别.

这里的关键使建立申报财产= 参加角逐的逻辑关系.
