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?

1. The increase in corn prices is due more to a decline in the supply of corn than to a growth in demand for it.


2. Generally, farmers who are squeezed out of the livestock business send their livestock to market much earlier than they otherwise would.


3. Some people who ate meat regularly in the past are converting to diets that include little or no meat.


4. As meat prices rise, the number of livestock producers is likely to rise again.


5. Livestock producers who stay in the business will start using feed other than corn more extensively than they did in the past.

Why the answer is B, not D?

Magazine Publisher:  Our magazine does not have a liberal bias.  It is true that when a book review we had commissioned last year turned out to express distinctly conservative views, we did not publish it until we had also obtained a second review that took a strongly liberal position.  Clearly, however, our actions demonstrate not a bias in favor of liberal views but rather a commitment to a balanced presentation of diverse opinions.

Determining which of the following would be most useful in evaluating the cogency of the magazine publisher’s response?

1. Whether any other magazines in which the book was reviewed carried more than one review of the book


2. Whether the magazine publishes unsolicited book reviews as well as those that it has commissioned


3. Whether in the event that a first review commissioned by the magazine takes a clearly liberal position the magazine would make any efforts to obtain further reviews


4. Whether the book that was the subject of the two reviews was itself written from a clearly conservative or a clearly liberal point of view


5. Whether most of the readers of the magazine regularly read the book reviews that the magazine publishes

Why the answer is C. I cann't understand the meaning of the passage?

1。D错的原因：producers增加不见得livestock的供给增加而导致价格减低

    B对的原因：那些被挤出生意的农民，为结束生意，通常没等livestock长到一定程度就卖掉（因为他们状况一样，被挤出市场时间差不多），从而导致市场短期供应过多而价格短期下降。

2。观点：我们的杂志没有倾向自由派，是中立的。理由：去年我们委托的书评持保守派观点，我们没立即出版，而是等到持自由派观点的书评出来才一起出版。问题：评估原文ARGUMENT。原文理由中明显看出杂志倾向自由派，如果相反，持自由派观点的书评先出来，而杂志没先出版，而等持保守派观点的书评出来才一起出版，才能证明杂志没有倾向自由派。即C

Why if the producers increase, the livestock won't increase, thus decrease the price. I think the price decrease will happen not immediately in short-term, but happen after a period of time. Is this the reason why D is wrong?

我也認為是如此 ,  因為c 不保證這些市場新進者的影響是暫時性的

我认为这里解题与corn没什么关系

corn价格上涨---->肉商利润下降---->部分肉商退出---->肉供应减少，肉价上涨

However, 观察家说肉短期内会降价，问支持

B解释了短期内肉供应为什么会增加（故肉价下降）
