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
答案E 我理解为 削弱题，E是怎么削弱的呢？作者: MarilynR 时间: 2011-1-15 12:51

换了小飞机后，造成其它飞机delay their takeoffs，就不是quick turnaround作者: judyenglishS 时间: 2011-1-15 21:12
