176. 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’ 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.
Northern Air has dozens of flights daily into and out of
Belleville Airport, which is highly congested(主要问题所在). 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’ fuel
efficiency results in both lower fuel costs and reduced time spent refueling.（解决问题.1主要问题：节约时间，2：次要优势，省钱）
fuel efficient 意味着用更少的油。那么即使油价下跌，skybus依然能够节约成本。所以B不能起到削弱作用。
但是E说明SKYbus可能会耽误更多的时间。从主要矛盾上削弱。
哦~~~ 明白！
谢谢
