标题: [求助]CR黄金８０题里的

马上要考试了，看了黄金８０，大脑快抽筋了．．．

请ＮＮ指教以下两题，想不出答案的逻辑思路

５． A recent poll found that over 80 percent of the residents of Nalmed Province favored a massive expansion of the commuter rail system as a means of significantly easing congestion on the province's highways and were willing to help pay for the expansion through an increase in their taxes. nevertheless, the poll results indicate that expansion of the rail system, if successfully completed, would be unlikely to achieve its goal of easing congestion, because______

A. most people in favor of expanding the rail system reported less congestion during their highway commute as the primary benefit they would experience

B of the less than 20 percent of residents not counted as favoring the expansion, about half claimed to have no opinion one way or the other

C the twice-daily periods of peak congestion caused by people commuting in cars have grown from about an hour each to almost two and a half hours each in the past 20 years

D expanding the commuter rail system will require the construction of dozens of miles of new railed

E the proposed expansion to commuter rail system will make it possible for some people who both live and work at suburban locations to commute by rail.

答案为什么是Ａ呢？　Ｅ为什么不对呢？

１３ Some species of Arctic birds are threatened by recent sharp increases in the population of snow geese, which breed in the Arctic and are displacing birds of less vigorous species. Although snow geese are a popular quarry for hunters in the southern regions where they winter, the hunting season ends if and when hunting has reduced the population by five percent, according to official estimates. Clearly, dropping this restriction [e1] would allow the other species to recover.

Which of the following, if true, most seriously undermines the argument?
A Hunting limits for snow geese were imposed many years ago in response to a sharp decline in the population of snow geese.
B It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date.
C The number of snow geese taken by hunters each year has grown every year for several years.
D As their population has increased, snow geese have recolonized wintering grounds that they had not used for several seasons.
E In the snow goose’s winter habitats, the goose faces no significant natural predation

完全不明白什么意思～

1。 A表示支持者都是开车上高架的，支持的理由为了更好的开车。即使增加铁路流量，这些人也不会改坐铁路。

谢谢sourthnorth GG的解释。

A的意识是说尽管扩了铁路，高速公路上的人不会变少，所以不能缓解告诉公路的拥堵问题！

终于明白了，之前都没搞清rail way和highway的区别，哎，还是阅读能力的问题呀！

那请问第二道呢~
