'response of subordinate' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'primate is about right' is the wordplay.
'primate' becomes 'ayeaye' (aye-aye is a kind of primate).
'about' says the letters should be written in reverse.
'right' becomes 'r' (common abbreviation).
'is' back-to-front is 'si'.
'ayeaye'+'si'+'r'='AYE AYE SIR'
