603. 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 poor people. Critics suggested alternatively that 9 fare tokens be sold for $10.00, because a $20.00 outlay would be prohibitive for poor riders.
The alternative proposal depends on which of the following assumptions?
A. Poor residents of Workney will continue to ride the buses in the same numbers despite the fare increase.
B. Riders who are poor would be more likely to take advantage of the savings afforded by the 9-token offer than would riders who are not poor.
C. The outlay of $10.00 for the purchase of 9 fare tokens would not be prohibitive for bus riders who are poor.
D. The proposed fare increase is needed for the purchase of new buses for the city’s bus system.
E. Fewer riders would regularly purchase 18 fare tokens at once than would purchase only 9 fare tokens at once.
题目大意
W国要把公交车票价从1刀涨到1.25刀，提议将18张票卖20刀，以减轻涨价给穷人带来的额外负担。批评家建议也可以9张票卖10刀，因为20刀的支出对贫穷的乘客来说是过高的。
解题思路
问题问备选方案基于哪个假设，备选方案是9张票卖10刀，这样做的理由是一次支出20刀对穷人来说太多了，只花10刀就能被穷人接受，所以选项要能使这个说法成立。
A：贫穷的乘客会继续乘坐相同次数的公交车，尽管涨价了。错，依旧要坐车和支出能不能被接受无关，还是会坐车就代表他们能接受10刀的花费吗？
B：穷人比不穷的人更可能利用9张票提供的储蓄。错，没有说花费的数额能不能被接受的问题。
C：花10刀去买9张票对于穷人来说不是过高的。正确，如果花10刀也接受不了，第二种方案就没法成立。
D：票价上涨是被城市公交系统购买新的公交车所需要的。错，买公交车与原文无关。
E：定期一次性买18张票的人比一次买9张的人少。错，原文主要讨论的是一次的花费，不是一次买多少票。
答案：C
