请教一道GWD-2-15

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.

这道题答案给的是C，只是将结论提升为前提。应该算是一道简单题吧。可是我当时选的是A，我有点不理解，其实A应该也算是一个大前提，如果乘客数量减少，那不管是多少钱都是没人去乘车啊。

请赐教！

文章中说, $20就会prohibitive

A说, 即使fare increase, 乘坐公车的低收入者数量不变...不变的话, 这么能说prohibitive呢?

我理解你的意思了，就是说A的这个前提是和题目冲突的。
