1。The chanterelle, a type of wild mushroom, grows beneath host trees such as the Douglas fir, which provide it with necessary sugars. The underground filaments of chanterelles, which extract the sugars, in turn provide nutrients and water for their hosts. Because of this mutually beneficial relationship, harvesting the chanterelles growing beneath a Douglas fir seriously endangers the tree.
Which of the following, if true, casts the most doubt on the conclusion drawn above?
(A) The number of wild mushrooms harvested has increased in recent years.
(B) Chanterelles grow not only beneath Douglas firs but also beneath other host trees.
(C) Many types of wild mushrooms are found only in forests and cannot easily be grown elsewhere.
(D) The harvesting of wild mushrooms stimulates future growth of those mushrooms.
(E) Young Douglas fir seedlings die without the nutrients and water provided by chanterelle filaments.

它不是明明说那两种东西是互利的嘛？为什么又说种那种蘑菇会危及树呢？答案又怎么解释？

11。Advertisement: The world’s best coffee beans come from Colombia. The more Colombian beans in a blend of coffee, the better the blend, and no company purchases more Colombian beans than Kreemo Coffee, Inc. So it only stands to reason that if you buy a can of Kreemo’s coffee, you’re buying the best blended coffee available today.
The reasoning of the argument in the advertisement is flawed because it overlooks the possibility that
(A) the equipment used by Kreemo to blend and package its coffee is no different from that used by most other coffee producers
(B) not all of Kreemo’s competitors use Colombian coffee beans in the blends of coffee they sell
(C) Kreemo sells more coffee than does any other company
(D) Kreemo’s coffee is the most expensive blended coffee available today
(E) the best unblended coffee is better than the best blended coffee

我选A ,答案是C，不明白，这是一则广告，说产品好，和所谓忽略的可能性，这个公司比其他公司卖出的多很什么关系?就算它已经是卖的最多了，难道就不能做广告了？不懂

13。A severe drought can actually lessen the total amount of government aid that United States farmers receive as a group. The government pays farmers the amount, if any, by which the market price at which crops are actually sold falls short of a preset target price per bushel for the crops. The drought of 1983, for example, caused farm-program payments to drop by $10 billion.
Given the information above, which of the following, if true, best explains why the drought of 1983 resulted in a reduction in farm-program payments?
(A) Prior to the drought of 1983, the government raised the target price for crops in order to aid farmers in reducing their debt loads.
(B) Due to the drought of 1983, United States farmers exported less food in 1983 than in the preceding year.
(C) Due to the drought of 1983, United States farmers had smaller harvests and thus received a higher market price for the 1983 crop than for the larger crop of the preceding year.
(D) Due to the drought of 1983, United States farmers planned to plant smaller crops in 1984 than they had in 1983.
(E) Despite the drought of 1983, retail prices for food did not increase significantly between 1982 and 1983.

“The government pays farmers the amount, if any, by which the market price at which crops are actually sold falls short of a preset target price per bushel for the crops. ”主要是这句话没看懂，请解释一下好嘛？

先谢过了

1。答案是选D吧。你没理解正确。不是蘑菇害树，是”采蘑菇“害树。题目的意思：
理由：2者存在互利的关系
结论：HARVEST 这个蘑菇会害了树
但理由并不推出HARVEST 这个蘑菇一定影响到它的HOST 树，如答案D，就提出HARVEST 蘑菇反而会刺激生出新的蘑菇，这样就不影响树咯。也就驳斥了题目中的结论。

2。答案是C。我觉的MM存在想的过远的问题。
题目的简单点说就是：K公司买了最多的哥伦比亚豆----含哥伦比亚豆越多的咖啡越好，所以K公司的咖啡产品最好。
答案C：如果K公司生产大量的咖啡，那就算K买了最多的哥伦比亚咖啡豆，每份咖啡里哥伦比亚豆含量也可能是行业最低。

3。我理解是：
如庄稼实际卖的市场价格低于预先政府定好的每BUSEL庄稼价格，政府将给负责农民有损失的部分。
答案C?

好感谢哦！我觉得做逻辑读懂题好重要的，而且比较郁闷的是刚开始练逻辑时错误率挺低的，现在竟然大不如前了。还有二十几天就考了。还来得及嘛？

以下是引用terry_awesome在2004-2-3 21:26:00的发言：

可是C说的是K卖了大量的咖啡，而不是生产了大量的咖啡啊……
