Proposed new safety rules for Beach City airport would lengthen considerably the minimum time between takeoffs from the airport. In consequence, the airport would be able to accommodate 10 percent fewer flights than currently use the airport daily. The city’s operating budget depends heavily on taxes generated by tourist spending, and most of the tourists come by plane. Therefore, the proposed new safety rules, if adopted, will reduce the revenue available for the operating budget.

The argument depends on assuming which of the following?

There are no periods of the day during which the interval between flights taking off from the airport is significantly greater than the currently allowed minimum. Few, if any, of the tourists who use Beach City airport do so when their main destination is a neighboring community and not Beach City itself. If the proposed safety rules are adopted, the reduction in tourist numbers will not result mainly from a reduction in the number of tourists who spend relatively little in Beach City. Increasing the minimum time between takeoffs is the only way to achieve necessary safety improvements without a large expenditure by the city government on airport enhancements. The response to the adoption of the new safety rules would not include a large increase in the number of passengers per flight.

题干翻译
新安全规则将使机场每日容纳航班数比目前减少10%。城市运营预算严重依赖游客消费产生的税收，且多数游客乘飞机来。因此，若新安全规则被采纳，将减少运营预算的可用收入。 逻辑链
New safety rules → Fewer flights → Fewer tourists → Less revenue 问题类型
假设题 推理过程
论点是新安全规则会减少运营预算的可用收入，论据是新安全规则导致航班减少，而游客多乘飞机来且运营预算依赖游客消费税收。要使论证成立，需假设新安全规则不会通过其他方式弥补因航班减少带来的游客数量和收入的减少。 选项分析
A选项：一天中是否有航班起飞间隔远大于目前允许最小值的时段，与新安全规则实施后收入是否减少无关，排除。 B选项：使用机场的游客目的地是哪里，和新安全规则对运营预算收入的影响无直接联系，排除。 C选项：游客消费多少的构成情况，不能说明整体收入是否会减少，排除。 D选项：实现安全改进的方式，与新安全规则实施后运营预算收入是否减少不相关，排除。 E选项：若采纳新安全规则后每个航班乘客数量不会大幅增加，就排除了通过增加单个航班乘客数量来弥补航班减少导致游客减少和收入减少的可能性，是论点成立的必要假设，当选。
