请教GWD2——10、12

Question 10:

Environmentalist:   The use of snowmobiles in the vast park north of Milville creates unacceptable levels of air pollution and should be banned.

Milville business spokesperson:   Snowmobiling brings many out-of-towners to Milville in winter months, to the great financial benefit of many local residents.  So, economics dictate that we put up with the pollution.

Environmentalist:   I disagree:  A great many cross-country skiers are now kept

from visiting Milville by the noise and pollution that snowmobiles generate.

Environmentalist responds to the business spokesperson by doing which of the following?

A.     Challenging an assumption that certain desirable outcome can derive from only one set of circumstances

B.     Challenging an assumption that certain desirable outcome is outweighed by negative aspects associated with producing that outcome

C.     Maintaining that the benefit that the spokesperson desires could be achieved in greater degree by a different means

D.   Claiming that the spokesperson is deliberately misrepresenting the environmentalist’s position in order to be better able to attack it

E.    Denying that an effect that the spokesperson presents as having benefited a certain group of people actually benefited those people

这道题目答案是E，我对此没有异议，但是我不明白为什么B是错的呢？我查了讨论贴还是不明白，谢谢大家。

Which of the following most logically completes the passage?

Concerned about financial well-being of its elderly citizens, the government of Runagia decided two years ago to increase by 20 percent the government-provided pension paid to all Runagians over 65.  Inflation in the intervening period has been negligible, and the increase has been duly received by all eligible Runagians.  Nevertheless, many of them are no better off financially than they were before the increase, in large part because ________.

A.     They rely entirely on the government pension for their income

B.      Runagian banks are so inefficient that it can take up to three weeks to cash a pension check

C.     They buy goods whose prices tend to rise especially fast in times of inflation

D.     The pension was increased when the number of elderly Runagians below the poverty level reached an all-time high

E.      In Runagia children typically supplement the income of elderly parents, but

only by enough to provide them with a comfortable living

这道题目答案是E但是我想不通，我想问最后一句话的意思是什么啊？是说：然而，这些年龄在65岁以上的人比价格上涨前没有得到较好的资金帮助，问为什么吗？我选的是C，谢谢大家。

B的意思反了."...is outweighed..."理解一下.

E是说子女资助老人到一定的限度. e.g.生活舒适的标准是每月100元. 过去政府补助是50,子女就给50.现在政府给75,子女就给25.总量不变.
