In only two decades Asian Americans have become the fastest-growing U.S. minority. As their children began moving up through the nation schools, it became clear that a new class of academic achievers was emerging. Their achievements are reflected in the nation’s best universities, where mathematics, science and engineering departments have taken on a decidedly Asian character. This special liking for mathematics and science is partly explained by the fact that Asian-American students who began their education abroad arrived in the U.S. with a sol id grounding in mathematics but little or no knowledge of English. They are also influenced by the promise of a good job after college. Asians feel there will be less unfair treatment in areas like mathematics and science because they will be judged more objectively. And the return on the investment in education is more immediate in something like engineering than with an arts degree.
Most Asian-American students owe
A. sympathetic
B. doubtful
C. critical
D. objective
