大神 C选项不懂
(C) 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.
游客减少不会源自于那些不消费的游客减少，意思就是说游客减少是源自于那些消费的游客数量减少。这个assumption看着也挺对的。。。 怎么破

说说我的理解：

Premise: Proposed new safetyrules would lengthen the minimum time between takeoffs from the airport.

Intermediate Conclusion: In consequent, theairport would accommodate 10% fewer flights than current.

Premise: Operating budget dependson taxes

Premise: Most of the touristscome by plane.

Conclusion: new safety rules will reduce the revenue.

10%fewer flights à less tourists à less revenue

Figure out an assumption by myself: Touriststake the impacted 10% flights.

A.There are no periods of the day [during which] the interval is significantlygreater than the currently allowed minimum.

飞机起飞间隔不会比现在最小间隔高太多。

Negation: There are periods of the day during which … 某个时间段特别busy, takeoff time很高. 即便如此，tourists不一定会少，fewer flights=/= fewer tourists. Cannot harm the conclusion.

B.Few of tourists spend money in Beach City.

即使few of tourists spend money in Beach City, they can spend a lot of money and the total revenue will not be reduced.

即使many of tourists spend money in Beach City, they can spend a littlemoney and the total revenue may still be reduced.

Outliers. Few/many of tourists spend little -/-> the overall revenue will be reduced/increased.

C.The reduction in tourist numbers will notresult mainly from the reduction in the number of “little-spending” tourists.

Negation: The reduction will result majorly from thetourists who spend little.

Outlier: majorly =/=100%; one of the tourists may spend a lot of moneyand increase the total revenue. Cannot harm the conclusion.

D.Irrelevant. It strengthens the intermediate conclusion, but does not harm themain conclusion.

E. The response would not include a large increase inthe number of passengers per flight.

If the number of passengers per flight is increased, the total number oftourists will be increased. Harm the conclusion.

If the number of passengers per flight is reduced, the total number oftourists will be reduced. Support the conclusion.

So, the assumption stated in E is airtight with thepremises and the conclusion.

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？
