问题补充：

—What do you think made Tina so delighted？

— the driving test at her first try.

A. As she passed

B. Passed

C. Because of passing

D. Passing

答案：

A. As she passed

B. Passed

C. Because of passing

(答案→)D. Passing

解析： 此题中do you think是插入语，what 在特殊疑问句中做主语，所以相应回答部分也要做主语，D项的动名词短语可以做主语 A. As she passed引导状语从句，做状语C. Because of passing也是原因状语 B. Passed过去分词短语也不能做主语
