Q015/Q016: seem doubled. Looks like an error and needs some context
The two questions are:
- Q015: Which programming languages have you used at work in the last 12 months?
- Q016: Which are your primary programming languages?
Same answers in both cases.
Without context or purpose of those two questions, I felt this is an error or something broke.
I propose to either:
- merge to one question, or
- add an explanatory sentence on top of it what exactly you want to achieve here.
