A defense contractor is about to unveil a new plane, which has taken several years and several billions of dollars to create. Many governmental observers are uneasy about its first flight, since its designers built it straight from a computer model without first building a prototype to test the plane's design, as is the usual procedure.

Which one of the following statements, if true, would be most likely to ease the governmental observers' concerns?

A) The new three-dimensional computer modeling technique used by the contractor simulates the trials typically faced by a prototype.
B) The Secretary of Defense has proposed delaying the deployment of this plane for one year.
C) This plane is susceptible to some of the same problems that caused the recent crash of another innovative plane.
D) Many positive features of the plane cannot yet be revealed because of national security considerations.
E) The computer model has already passed a battery of Department of Defense quality checks

As the governmental observers' concerns is the designers built it straight from a computer model without first building a prototype to test the plane's design, as is the usual procedure.

therefore the answer have to be related to the prototype.

Answer A.

A few different ways to get there:

Logically, the problem stated in the stem involves not having a prototype - therefore we should expect an answer which mentions prototypes - only A does that.

Precise solution: the problem is that the plane was designed without a prototype, therefore what would ease the concern is being told that the design achieved the goals that prototypes do. Exactly what A tells us.

An alternative solution is using the answers:

A) The new three-dimensional computer modeling technique used by the contractor simulates the trials typically faced by a prototype. Great - if this is the case, then not having the prototype seems like no problem. Concern eased.
B) The Secretary of Defense has proposed delaying the deployment of this plane for one year. This only strengthens the concern
C) This plane is susceptible to some of the same problems that caused the recent crash of another innovative plane. This only strengthens the concern
D) Many positive features of the plane cannot yet be revealed because of national security considerations. Neither here nor there
E) The computer model has already passed a battery of Department of Defense quality checksThis is good news in general, but really doesn't relate directly to the specific concern raised
