Fill in answer from previous questions

Hi all,
I am looking for JS solution. I would like to auto fill in question based on the previous answers (both multiple choice). Carry forward choices won't work in this case as the answers are slightly different. To sum up: If respondent select certain response in Q1, i need automatically fill in certain response in Q2. For certain reasons I do not want to use Skip Logic as I need the respondent to see the answer and possibly modify it.
