When an airplane is taken out of service for maintenance, it is often repainted as well, and during the repainting no other maintenance work can be done on the plane. In order to reduce maintenance time, airline officials are considering using a new nontoxic plastic film instead of paint. The film takes just as long to apply as paint does, but many other maintenance tasks can be carried out at the same time.

Which of the following, if true, is further evidence that using the film will help the airline officials achieve their goal?

A. Unlike paint, the film gives a milky tone to certain colors.

B. At the end of its useful life, the film can be removed much more quickly than paint can.

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. Even at speeds considerably higher than the normal speed of a passenger jet, the film remains securely attached.

This argument is all about using the plastic film in place of paint in order to cut down on maintenance time. The piece of evidence offered is that, while it takes as long to apply as does paint, other tasks can be done in the interim. This means there is less "down time" for the other tasks. If, in addition to this benefit during the application process, the removal process for the film is also faster then you are speeding up the process even more. Being able to remove the used film quicker than being able to scrape off the old paint means that now you remove the film faster and then have less down time for other tasks, thus making the process even more fast.

I hope this helps!!!

Why not E?

The primary purpose of any paint/plastic used for colouring the plane is to stay on while the plane is in flight. It is established in the stem that the plastic will save time. But what good is this "saving time", if the plastic will come off during flight? Plastic can only be used if it also saves time while doing all of the core functions that paint does. The stem doesnt elaborate on this fact - whether the plastic does all of the functions for the plane that paint colour does. I think we need to fill that logic gap and hence E is superior to B.

Note I have no doubt about B's strengthening ability. I just think E strengthens the argument more than B.

A. Unlike paint, the film gives a milky tone to certain colors. --> What Color is Irrelevant

B. At the end of its useful life, the film can be removed much more quickly than paint can. --> Correct
Let's negate this: "At end of life, removing film can NOT be removed much more quickly than paint can."
Say paint takes 1 day to remove and 3 days to apply. So days taken = 4. And say film takes 5 days (more than 1) to remove. So days taken = 5.
This shatters the conclusion that film is better than paint. So this is an assumption/strengthener.

C. The film can be applied only by technicians who have received special training. --> Whether training is required or not is not a concern. Out of scope.

D. The metal exteriors of airplanes have to be protected from high temperatures and caustic chemicals such as exhaust gases. --> Irrelevant to paint or film.

E. Even at speeds considerably higher than the normal speed of a passenger jet, the film remains securely attached. --> We do not need to know what happens if Jet goes beyond normal speed. Further we don't even know if paint also lasts in such scenario. Plus this has nothing to do with time saving during maintenance.

One reason is given about why it is better to use the film than paint. Now you need a choice that further proves same. But keep in mind that a choice can only support if it uses the right parameter. In argument Time is the most important parameter. Infact Time is the reason for using film as an alternative of paint.

A. Unlike paint, the film gives a milky tone to certain colors.
Is this why we looked out for alternative to paint?? Of course not. Irrelevant.

B. At the end of its useful life, the film can be removed much more quickly than paint can.
If film is so good that it is a time saver even after its use than it is better to use. So this choice support using the Time as parameter. Stays in scope and hits the right note. Good choice. Correct choice.

C. The film can be applied only by technicians who have received special training.
Well that’s not an issue. paint is also applied by painters.

D. The metal exteriors of airplanes have to be protected from high temperatures and caustic chemicals such as exhaust gases.
So no information on film and paint. OFS.

E. Even at speeds considerably higher than the normal speed of a passenger jet, the film remains securely attached.
So this one tells how good it is to use film. But then this choice is away from WHY officials wanted to use film. They wanted to save time. This security is not the concern in argument.

Boil it down - Replacing paint by plastic film will reduce maintenance time

A. Unlike paint, the film gives a milky tone to certain colors. - Irrelevant

B. At the end of its useful life, the film can be removed much more quickly than paint can. - Correct

C. The film can be applied only by technicians who have received special training. - Irrelevant

D. The metal exteriors of airplanes have to be protected from high temperatures and caustic chemicals such as exhaust gases. - Irrelevant

E. Even at speeds considerably higher than the normal speed of a passenger jet, the film remains securely attached. - ISWAT - we don't even know whether the plane does travel at speeds considerably higher than normal speed . Also , paint might still be secured at higher than normal speeds.

Answer B
