32. In comparing the United States government’s definition
of services with the classical definition, the author
suggests that the classical definition is
(A) more pragmatic
(B) more difficult to apply
(C) less ambiguous
(D) more widely used
(E) more arbitrary
为什么答案是B，不是C，
原文26行不是说Such ambiguities reveal the arbitrariness
of this definition吗，取非不就是C了吗？谢谢
