Which of the following, if true, most logically completes the passage? 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 of 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 railroads. E. the proposed expansion to the commuter rail system will make it possible for some people who both live and work at suburban locations to commute by rail. A 不理解这题，请解答！谢谢！我选了E。A 有什么关系啊？ Lyme disease is caused by a bacterium transmitted to humans by deer ticks. Generally deer ticks pick up the bacterium while in the larval stage from feeding on infected white-footed mice. However, certain other species on which the larvae feed do not harbor the bacterium. Therefore, if the population of these other species were increased, the number of ticks acquiring the bacterium and hence the number of people contracting Lyme disease would likely decline. Which of the following, if true, most strengthens the argument?
A. Ticks do not suffer any adverse consequences from carrying the bacterium that causes Lyme disease in humans. B. There are no known cases of a human’s contracting Lyme disease through contact with white-footed mice. C. A deer tick feeds only once while in the larval stage. D. A single host animal can be the source of bacterium for many tick larvae. E. None of the other species on which deer tick larvae feed harbor other bacteria that ticks transmit to humans C 有关系吗？我觉得A还有点侧面加强因果 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 cashew 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?
A. Some of the by-products of processing cashews are used for manufacturing plants and plastics B. Other countries in which cashews are processed subsidize their processing plants C. More people in kernland are engaged in farming cashews than in processing them D. Buying unprocessed cashews at lower than world market prices enables cashew processors in kernland to sell processed nuts at competitive prices E. A lack of profitable crops is driving an increasing number of small farmers in kernland off their land and into the cities E 有关系吗？我觉得没有对的啊？ E只是说明还有其他的原因使得失业率升高但是并不能够削弱原文的逻辑链条：process 工场受损---》失业升高。
