---makes the matter worse is that I don have a single copy．

A. It

B. What

C. That

D. Which

答案：

A. It

(答案→)B. What

C. That

D. Which

解析：主要测试主语从句。由的语境可知句子---makes the matter worse 中需要主语，同时该句子还充当了后面句子is that I don have a single copy的主语，双重作用，结合答案可知选择what。译文：----那么说你没有理解信息表了？----更糟糕的是我一份文件也没有啊。
