—what do you think of the matter?

—Don’t you remember I have already that it was troublesome?

A. made it clear

B. made clear

C. took it for granted

D. made sure

答案：

(答案→)A. made it clear

B. made clear

C. took it for granted

D. made sure

解析：made it clear说明白；took it for granted认为理所当然；made sure确保。句意：你认为这件事情怎么样？难道你不记得我已经说清楚了它是一个大麻烦。Made的真正宾语是that it was troublesome，所以用it作形式宾语。选A。
