后天就要考试了, 有几道题一直找不到解释, 请指点!!! 多谢

GWD 3 - 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?

 

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

   Answer: E (why not C)

GWD 15 - Q38:

In one state, all cities and most towns have antismoking ordinances.  A petition entitled “Petition for Statewide Smoking Restriction” is being circulated to voters by campaign workers who ask only, “Do you want to sign a petition for statewide smoking restriction?”  The petition advocates a state law banning smoking in most retail establishments and in government offices that are open to the public.

 

Which of the following circumstances would make the petition as circulated misleading to voters who understand the proposal as extending the local ordinances statewide?

 

1. Health costs associated with smoking cause health insurance premiums to rise for everyone and so affect nonsmokers.
2. In rural areas of the state, there are relatively few retail establishments and government offices that are open to the public.
3. The state law would supersede the local antismoking ordinances, which contain stronger bans than the state law does.
4. There is considerable sentiment among voters in most areas of the state for restriction of smoking.
5. The state law would not affect existing local ordinances banning smoking in places where the fire authorities have determined that smoking would constitute a fire hazard.

   Answer: E (why not C)

GWD 7 - Q13:

It is true of both men and women that those who marry as young adults live longer than those who never marry.  This dose not show that marriage causes people to live longer, since, as compared with other people of the same age, young adults who are about to get married have fewer of the unhealthy habits that can cause a person to have a shorter life, most notably smoking and immoderate drinking of alcohol.

 

Which of the following, if true, most strengthens the argument above?

 

1. Marriage tends to cause people to engage less regularly in sports that involve risk of bodily harm.
2. A married person who has an unhealthy habit is more likely to give up that habit than a person with the same habit who is unmarried.
3. A person who smokes is much more likely than a nonsmoker to marry a person who smokes at the time of marriage, and the same is true for people who drink alcohol immoderately.
4. Among people who marry as young adults, most of those who give up an unhealthy habit after marriage do not resume the habit later in life.
5. Among people who as young adults neither drink alcohol immoderately nor smoke, those who never marry live as long as those who marry.

   Answer:  C  (why not D)
