标题: xdf 的一道题

The city of Workney, in raising bus fares from $1.00 to $1.25, proposed that 18 fare tokens be sold for $20.00 to alleviate the extra burden of the fare increase on the city’s low-income residents. Critics suggested alternatively that 9 fare tokens be sold for $10.00, because a $20.00 outlay would be prohibitive for low-income riders.

The alternative proposal depends on which of the following assumptions?

A. Low-income residents of Workney will continue to ride the buses in the same numbers despite the fare increase.

B. Low-income riders would be more likely to take advantage of the savings afforded by the 9-token offer than would other riders.

C. The outlay of $10.00 for the purchase of 9 fare tokens would not be prohibitive for low-income bus riders.

D. The proposed fare increase is needed for the purchase of new buses for the city’s bus system.

E. Buses provide the only means of public transportation in the city of Workney.

答案 c 没问题。问一下， A 为什么不好？ b 为什么不好？

W城的票价从1升到1.25，W城提出18个TOKENS卖20（应该卖22.5）以减轻增加的费用对低收入人群造成的额外负担，批评者另外提出建议9个TOKENS卖10（应该卖11.25），因为20的费用对低收入人群太高了。

C取非，10元对于低收入人群太高了，削弱结论。
