What you posted isn't a multiquery. A proper multiquery should get you what you want:
{
'question_detail':
'SELECT id, question FROM question WHERE owner = me()
ORDER BY created_time DESC LIMIT 1',
'question_answers':
'SELECT name, votes FROM question_option WHERE question_id IN
(SELECT id FROM #question_detail)'
}
You'll need to get rid of the whitespace for this to properly execute.
