Display questions and print only answers

Hi all,

I have new logic to be worked. Please help me to sort it out.

I have 10 set of questions and 10 simple questions in each set.
Out of 10 simple questions I would like to get any random questions to be popped. And the answer should be displayed only for that questions instead of all the 10 simple questions of a set. IS it possible?

Below is the logical output to be downloaded. Please help to sort this out.
Question set 1 Question set 2 **
** Q1 Q2 Q3 Q4 Q5 Q6 Q7 Q8 Q1 Q2 Q3 Q4 Q5 Q6 Q7 Q8

**Survey 1 2 5 **
**Survey 2 5 6 **
Survey 3 7 1

Thanks in advance
