'incomprehension' is the definition.
Both the answer and definition are singular nouns.
Perhaps they are linked in a way I don't understand?

'risk encompassing creative stimulus for workers' is the wordplay.
'risk' becomes 'bet'.
'encompassing' means one lot of letters goes inside another.
'creative stimulus for' becomes 'muse' (I can't explain this - if you can you should give a lot more credence to this answer).
'workers' becomes 'men' (man is a kind of worker).
'muse'+'men'='musemen'
'bet' enclosing 'musemen' is 'BEMUSEMENT'.

'of' acts as a link.

(Other definitions for bemusement that I've seen before include "stupefaction" , "Confusion, bewilderment" , "state of perplexity" .)
