问题 Key resources are technical personnel and aircraft spare parts which account for the largest share of the maintenance ______.
选项 A、expenditure
B、budget
C、allowance
D、investment
答案 B
解析 近形近义题。resources暗示了technical personnel和spare parts是需要预先储备好、以备后用的。因此，在财政上只能作为预算，[B]budget“预算”符合句子的语义，为正确答案。[A]expenditure“花费”、 [C]allowance“津贴，补助”和[D]investment“投资”这三项都不符合句子的语义关系。
