How to move the content of 'Node content' display (Views) to the end of a view?
Have you tried playing with the "Row style" setting ? You could change it to "Fields" and select the node:title, node:body, node:nid and node:answers (?? does that exist ?? I'm guessing that answers are just comments, right ? In that case, node:comments).

Output them in the order that you want, but rewrite the node:nid as a link to the "post answer" url. I don't know this module, but say the answer url is node/xxx/answer, you can rewrite the node:nid field as 

&lt;a href="/node/[nid]/answer"&gt;Post your answer&lt;/a&gt;
