You have to convert the question, hint and answer environment.
What the block environment does is to save the content from the begin to the
end block and hides it when you use \hideblocks[…]. To output the content of
the environments you can use \useblocks[…].
\defineblock[question]
\defineblock[hint]
\defineblock[answer]
\defineenumeration[question][alternative=hanging,text={Question},stopper={.}]
\defineenumeration[hint] [alternative=hanging,text={Hint for
question},stopper={.}]
\defineenumeration[answer] [alternative=hanging,text={Answer to
question},stopper={.}]
\keepblocks[question]
\hideblocks[hint]
\hideblocks[answer]
\starttext
\section{Questions}
\beginquestion
\startquestion

\stopquestion

\stopanswer
\endanswer
\endquestion
\beginquestion
