Answer 1

你给的第一句有问题吧？改正后再变化：
1.Mary bought 【two expensive shirts】 half -an hour ago
What did Mary buy half -an hour ago?
2.The man who Caroline served was wearing a hat.(变成一般疑问句)
Was the man who Caroline served wearing a hat?

祝你进步，时时开心！O(∩_∩)O~~

What did Cary buy an hour ago?
Was the man who Caroline served wearing a hat?
这位同学，提点建议，大小写请区分清楚，另第一句貌似词不达意，请检查你的句子输入是否有错误。：）
