This file looks inconsistent from here.  Is it the case that there is no
comma on a line by itself between ,answer and ,question2 ?  If so you have
a harder task.  If there is always a comma by itself on a line, you have a
suitable separator.

This would be my approach, not from any innate superiority of the method,
more from a lack of sed knowledge.  My bash script would do something

exec < file

read LINE

echo $LINE | grep '^,$' > /dev/null

if [ $? .eq 0 ]; then
read LINE2
read LINE3
echo "$LINE $LINE2 $LINE3" > outfile

and something to iterate over the file...
