问题补充：

It can be cheaper to buy a new washing machine than to get your old one .

A. repaired

B. to repair

C. repairing

D. having repaired

答案：

(答案→)A. repaired

B. to repair

C. repairing

D. having repaired

解析：根据句意可知，句中的 your old one 与动词 repair 之间为被动关系，所以 repair 要用过去分词。get sth done 的意思是“使某事被做”。
