But some day, all our hard work will; we will attend the university of our choice and go on to have a great career.

A. turn out

B. pay off

C. work out

D. go out

答案：

A. turn out

(答案→)B. pay off

C. work out

D. go out

解析：turn out后应跟to do/to be/well等;work out“锻炼、结果”应跟well等副词；go out“熄灭、出去”都不合题意。句意“我们所有的努力都有好的结果”，故pay off“有好的结果”符合题意。
