When airplanes are taken out of service for maintenance, they are often repainted. Having an airplane out of service is extremely costly to an airline, and during repainting, no other maintenance can be done. In an attempt to reduce expenses associated with maintenance, airline officials are considering using a new plastic film, which is applied in sheets, instead of paint. However, the film is more expensive than paint, lasts no longer, and takes as long to apply.
Which of the following, if true, argues most strongly that use of the film will help the airline officials in their attempt to reduce expenses?
A. While the film is being applied, other workers can do maintenance work on the plane.
B. Unlike paint, the film gives a milky tone to certain colors.
C. The film can be applied only by technicians who have received special training.
D. The metal exteriors of airplanes have to be protected from high temperatures and caustic chemicals such as exhaust gases.
E. Special ripples in the film reduce a plane’s air resistance and thus reduce fuel costs.
