If the subsequent questions are identical then a select_one communities with a matching choice list is all you need. Each survey feature will have that community logged so you can aggregate and pivot easily.
If there's differences in the questions based on the community, then things get tricky. If it's the same field set but different choices/constraints/etc. then you can use tools like cascading selects or conditional statements in constraints (e.g. . < if(${community} = 'San Francisco', 80, 40)). If the fields change between communities this will make the analysis more difficult as each community has to be treated differently but this is easy to do in the survey form, just use a condition in the relevant column to only show the correct fields for each community.
