Proposed new safety rules for the 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?
- AThere 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.
- BFew, if any, of the tourists who use the Beach City airport do so when their main destination is a neighboring community and not Beach City itself.
- CIf 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.
- DIncreasing 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.
- EThe response to the adoption of the new safety rules would not include an increase in the number of passengers per flight.
正确答案是E,我明白为什么是E了,那么请问D为什么不对呢?如果有别的更好的方式来提高安全,就不用延迟飞机起飞间隔的时间了呀,难道论证不是建立在这之上的吗?
