You need 2 changes for \setupparagraphintro:

1. Change the argument of \hspace to "dist" because the commands accepts 
only keywords and everything else (even a valid length) is ignored and 
results in a horizontal skip of 0pt.

2. You have to add curly braces around the content when the content 
includes square brackets because nesting of optional arguments isn't 
supported yet.

The correct version of the one above is:

\startsetups[question:intro]
    \setupparagraphintro[first][{\bold{Answer:}\hspace[dist]}]
    \blank
\stopsetups
