Employers often give jobs to they believe has work experience and a stong sense of duty.

A. whoever

B. whomever

C. who

D. whom

答案：

(答案→)A. whoever

B. whomever

C. who

D. whom

解析：考查宾语从句：句意：老板经常把工作给他们相信有工作经验和强烈的责任感的人。Whoever引导宾语从句，在宾语从句中whoever做主语，=anyone who，因为在宾语从句中做主语，所以不能用 whomever，who和whom应该引导定语从句，前面缺少先行词，选A。
