单选题 If excellent work results in frequent pay increases or promotions, the workers will have greater ______ to produce.
A. incentive B. initiative C. instruction D. instinct

【正确答案】 A

【答案解析】[解析] incentive刺激，鼓励，动机；initiative主动的行动，进取心(强调自发地处州问题的能力，进取精神)；instruction教导，教育；instinct本能。本句中pay increases or promotions暗示了人们不愿自动地进取，而采用这些手段来刺激他们去干，故选A。
