The fact that only one jumbo-jet manufacturer remains in the United States is of great concern to the President, since our national defense requires the ability to transport large numbers of people over great distances. Before the President publicly connected this issue to that of import quotas on jumbo jets, however, the domestic manufacturer raised the national defense issue in its publicity campaign for import quotas.

Which of the following, if true, contributes most to an explanation of the domestic jumbo-jet manufacturer's raising the issue of national security?


(A) When airlines order new jumbo jets, they provide a large amount of work for aircraft manufacturers.

(B) The President is not very concerned with the impact of international competition on the domestic jumbo-jet industry.

(C) The manufacturer encountered resistance to public acceptance of import quotas on jumbo jets when it cited other rationale besides the national defense argument.

(D) Most of the military's operations do not require the use of jumbo jets.

(E) The domestic manufacturer recently received several orders from both airline and military sources, and these orders will allow that firm to compete successfully with its foreign competitors.
