During the Cold War, most overseas travel from the United

During the Cold War, most overseas travel from the United States was to places in Western Europe. At that time, because of the war or because of other regional instability, travel to Western Europe was much less risky than travel to other parts of the world. But in recent years this has become less and less the case. Now many other countries are open to travel that are just as safe as Western Europe but are also cheaper and, in most instances, as full of things to do and see. Paradoxically, more people than ever are traveling to Western Europe over these other countries.

Which of the following, if true, contributes most to a resolution of the paradox discussed above?

(A) U.S. travelers feel at least as safe in Western Europe as they would in the other countries.
(B) U.S. travelers recognize the better value of travel to Western Europe.
(C) Many airlines would love to acquire exclusive rights to offer flights to some Western European countries.
(D) At one point in time, it was much more difficult to arrange travel to non-Western European countries.
(E) The governments of Western European countries are very concerned with having Americans travel there, so they sometimes transfer the advertising of their country`s merits to other advertising firms.
