Depends a bit on how you have creates these questions.
The easiest (and translateable) option would be to create the dropdowns by using a "scale" question and set the layout to "dropdown". Then create a combined question from the 3 (first example) or 4 (second example) questions.
If you have create this question with placeholders, then you did a lot of copy & paste. Well, not easy to maintain, but still manageable. In this case, you have some HTML code - either directly in the questionnaire, or stored in a text element. If you have not yet stored it in a text element, you should move it there. This will make translation much easier.
