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.

answer C, I can understand, but why B is wrong? thx

我觉得

可能是因为文章中没有提到other riders

Low-income riders would be more likely to take advantage of the savings afforded by the 9-token offer than by the 18-token

好像更合理一些 我也做错了这道题， 所以不敢确定

文章推理是：因为 $20.00 outlay would be prohibitive for low-income riders，所以应该采取9 fare tokens be sold for $10.00的策略。
问上面推理的假设。

B.       Low-income riders would be more likely to take advantage of the savings afforded by the 9-token offer than would other riders. 文中没有出现other riders，所以这个比较无意义，无关；

 一下子拿出20块钱对低收入家庭来说是一笔不小的支出。换成10块钱一套就相对好点。再举个例子，比如可支配收入只有15块钱，就买不起20块的套票了，只买得起10块的。

最低门槛从20块降到10块。
