问题 A pervasive negative attitude of the engineers toward projects funded by his company is the cause of the delay of signing the contract.

选项 A、perpetual
B、pernicious
C、preventive
D、prevalent

答案D

解析 pervasive意为“普遍深入的”。D项prevalent“普遍的”符合题意,如:The habit of travelling by aircraft is becoming more prevalent each year.(坐飞机旅行一年比一年普遍了。)其他三项perpetual“永久的”,pernicious“有害的”,preventive“预防的”都不正确。
