标题: [讨论]GWD3里面好几道都搞不懂

这样三道一起问好象太猛了,不过实在是没辙了,谢谢各位:

Q2:

Kernland imposes a high tariff on the export of unprocessed cashew nuts in order to ensure that the nuts are sold to domestic processing plants. If the tariff were lifted and unprocessed cashews were sold at world market prices, more farmers could profit by growing cashews. However, since all the processing plants are in urban areas, removing the tariff would seriously hamper the government’s effort to reduce urban unemployment over the next five years.

Which of the following, if true, most seriously weakens the argument? E

Some of the by-products of processing cashews are used for manufacturing paints and plastics.
Other countries in which cashews are processed subsidize their processing plants.
More people in Kernland are engaged in farming cashews than in processing them.
Buying unprocessed cashews at lower than world market prices enables cashew processors in Kernland to sell processed nuts at competitive prices.
A lack of profitable crops is driving an increasing number of small farmers in Kernland off their land and into the cities.

Q30

The percentage of households with an annual income of more than $40,000 is higher in Merton county than in any other county. However, the percentage of households with an annual income of $60,000 or more is highest in Sommer county.

If the statements above are true, which of the following can properly be concluded on the basis of them? B

No household in Merton county has an annual income of $60,000 or more.
Some households in Merton county have an annual income between $40,000 and $60,000.
The number of households with an annual income of more than $40,000 is greater in Merton than in Sommer county.
Average annual household income is higher in Sommer than in Merton county.
The percentage of households with an annual income of $80,000 is higher in Sommer than in Merton county

Q40

For most people, the left half of the brain controls linguistic capabilities, but some people have their language centers in the right half. When a language center of the brain is damaged, for example by a stroke, linguistic capabilities are impaired in some way. Therefore, people who have suffered a serious stroke on the left side of the brain without suffering any such impairment must have their language centers in the right half.

Which of the following is an assumption on which the reasoning in the argument above depends?

No part of a person’s brain that is damaged by a stroke ever recovers.
Impairment of linguistic capabilities does not occur in people who have not suffered any damage to any language center of the brain.
Strokes tend to impair linguistic capabilities more severely than does any other cause of damage to language centers in the brain.
If there are language centers on the left side of the brain, any serious stroke affecting that side of the brain damages at least one of them.
It is impossible to determine which side of the brain contains a person’s language centers if the person has not suffered damage to either side of the brain.

Answer: D
