Airlines are considering applying a new plastic film to airplanes instead of paint. It is clear that airlines should adopt this new technology right away, since it would reduce the time that an airplane is out of service for maintenance. When an airplane is taken out of service for maintenance, it is often repainted. During repainting, no other maintenance work can be done on the plane, but other maintenance tasks can be done while the nontoxic plastic film is being applied. In addition, switching to the film would not increase maintenance costs in labor and materials, since the film is as quick to apply as paint without being more expensive.
In the argument given, the two portions in boldface play which of the following roles?The argument’s main conclusion is that airlines should adopt the new plastic film right away. The first boldface portion supports that conclusion by giving one benefit: less time out of service. The second boldface portion also supports the conclusion by saying that switching would not raise maintenance costs.
Both boldface portions are considerations in favor of the recommendation.
A. The first is the main position that the argument seeks to establish; the second is a consideration put forward in support of that position.
This is incorrect. The first boldface portion is not the main position. The main position is that airlines should adopt the film right away.
B. The first and the second are each considerations that are put forward in support of the position that the argument seeks to establish.
This is correct. The first gives an operational advantage, and the second says there is no added labor or materials cost. Both support
adopting the new film.
C. The first is a consideration that is put forward in support of the position that the argument seeks to establish; the second is an assumption for which no justification is offered.
This is incorrect. The second boldface portion is not merely an unsupported assumption; the argument supports it by saying the film is as quick to apply as paint and is not more expensive.
D. The first is presented as an advantage of following the recommendation made by the argument; the second is presented as a drawback to following that recommendation.
This is incorrect. The second is not a drawback. It is presented as another reason in favor of switching.
E. The first and the second are each presented as a drawback to following the recommendation made by the argument.
This is incorrect. Both portions support the recommendation.
