What an enquiring person would do to get an answer (5,1,8)

'what an enquiring person would do to get an answer' is the definition.
The definition suggests a singular noun which matches the answer.

'would do to get an answer' is the wordplay.
'would do' becomes 'question' (I can't justify this - if you can you should give a lot more credence to this answer).
'to' says to put letters next to each other (I've seen this in other clues).
'get' becomes 'raise' (as in to raise or get money).
'an answer' becomes 'a' (abbreviation eg in Q and A).
'raise'+'a'='raisea'
'question' after 'raisea' is 'RAISE A QUESTION'.
