Verbal (CR)

At one time, European and Japanese companies tried to imitate their American rivals. Today, American appliance manufacturers import European scientists to lead their research staffs; American automakers design cars that mimic the styling of German, Italian, and French imports; and American electronics firms boast in their advertising of Japanese-style devotion to quality and reliability. In the world of high technology, America has lost the battle for international prestige.

Each of the following statements, if true, would help to support the claim above EXCEPT:

(A) An American camera company claims in its promotional literature to produce cameras as fine as the best Swiss imports.
(B) An American maker of stereo components designs its products to resemble those of a popular Japanese firm.
(C) An American manufacturer of video games uses a brand name chosen because it sounds like a Japanese word.
(D) An American maker of televisions studies German-made televisions in order to adopt German manufacturing techniques.
(E) An American maker of frozen foods advertises its dinners as Real European-style entrees prepared by fine French and Italian chefs.
