问题补充：

—Who should be responsible for the accident?

—The boss，not the workers.They just carried out the order .

A. as told

B. as are told

C. as telling

D. as they told

答案：

(答案→)A. as told

B. as are told

C. as telling

D. as they told

解析：句意：——谁应当对这一起事故负责？——是老板，而不是工人。工人们只是执行了被吩咐的命令。workers和tell之间应当是被动关系，排除C、D。而当从句主语和主句主语一致，且从句中有be动词时，那么从句主语和be动词可以同时省去。末句可以补全为：They just carried out the order as they were told.
