Personally I would go with one “Questionnaire” object and an object for each question. This has the added benefit of being able to add additional attributes/specializations to each question (for instance, question type for multiple choice, short text, long text, etc).
I think it depends on what you are going to do with the objects. I agree with Eline. It seems to be more logical to have one object per question. It already feels more natural.
That also means that you need to work with lists of objects. With al pros and cons. It may be more work at first sight, but I guess it is worth it.
