问题补充：

Before driving into the city, you are required to get your car.

A. washed

B. wash

C. washing

D. to wash

答案：

(答案→)A. washed

B. wash

C. washing

D. to wash

解析：考查使役动词。get, make, let, have是使役动词，意为“使，让”，make/let/have sb do sth；get sb to do sth让某人做某事；get/have sth done让某事被别人做，car和wash是动宾关系，应该用过去分词，故选A。
