You could keep the content outside of the asset in standard pages for example, and then use the asset contents keyword as a modifier based on the response value from the select field response. For example:
%response_1234_q1^eq:value1:1111:0001^as_asset:asset_contents_raw%
%response_1234_qa^eq:value2:2222:0001^as_asset:asset_contents_raw%
%response_1234_q1^eq:value3:3333:0001^as_asset:asset_contents_raw%
etc...
Where 1111, 2222, 3333 are asset ids of standard pages with your content, and 0001 is an asset id of a standard page or div with no content in it (in case you get errors trying to do as_asset modification on something that is not an asset ID.
