118.  Northern Air has dozens of flights daily into and out of Belleville Airport, which is highly congested. Northern Air depends for its success on economy and quick turnaround and consequently is planning to replace its large planes with Skybuses, whose novel aerodynamic design is extremely fuel efficient. The Skybus’s fuel efficiency results in both lower fuel costs and reduced time spent refueling.

Which of the following, if true, could present the most serious disadvantage for Northern Air in replacing their large planes with Skybuses?

(A)  The Skybus would enable Northern Air to schedule direct flights to destinations that currently require stops for refueling.

(B)  Aviation fuel is projected to decline in price over the next several years.

(C)  The fuel efficiency of the Skybus would enable Northern Air to eliminate refueling at some of its destinations, but several mechanics would lose their jobs.

(D)  None of Northern Air’s competitors that use Belleville Airport are considering buying Skybuses.

(E)  The aerodynamic design of the Skybus causes turbulence behind it when taking off that forces other planes on the runway to delay their takeoffs.

B The decline in the price of aviation fuel might make the plan seem less pressing, and it could conceivably complicate the issue of whether the expected savings would justify the investment in

new planes. However, lower fuel costs would not diminish the crucial time-saving advantage of Skybuses, and any hypotheses about their relevance  to the overall decision are purely speculative.

C The ability to eliminate refueling is an advantage to the airline. The loss of jobs could, in theory,

have some negative effect on the airline due to lowered morale among remaining employees.

However, several  does not support a hypothesis that the effect would be very significant, and any hypotheses about whether it might override the benefits are purely speculative.

这题答案清楚，就是想请大牛帮忙分析上面蓝色句子，是不是有规律可循？以这题为例，求分析。

这题的意思是这家航空公司的竞争优势在于它的economy and quick turnaround.但实际情况是机场堵塞，因此高管决定买fuel efficient的飞机来强化优势。

因此明确决策的依据是新飞机的优点的是time-saving,而不考虑成本啊，人员雇佣之类的问题，尽管一般决策的时候会把很多因素都考虑进来。

这2句话的意思，就是告诉你不要考虑其他因素，因为它们是speculative的，文中没有依据。

嘻嘻……我og的逻辑没有这么认真的研究说来惭愧呀~

恩恩，这个懂的。我只是纠结OG的解释呢。。我觉得应该有玄机。求详细指导那2句话。

题干的大背景呢是
Northern Air has dozens of flights daily into and out of Belleville Airport, which is highly congested。
所以要攻击的话就是要和这个有关
b,c虽然是缺点，但都对这个背景没有任何作用，算是无关的吧
