I'm totally confused

In the preivew and the forum post, you want a line break after the answer before the next question?

That's done in the newthread_start plugin.

Look around line 126 in the plugin code
$comment_boxes .= '</td><td valign="top">';

changing it to
$comment_boxes .= '<br /></td><td valign="top">';

may do what you want

I havent figured out a way to template that bit of logic yet, so it's a little.. wonkey.
