I get those beer mugs all the time, Ko. They always make one's 'point B' look slightly frivolous.
I wonder whether the person who set the question wanted you to use 'quotation' instead, e.g.
'He introduced a quotation from Faulkner [into the conversation].'
Or was it the verb 'introduced'?
'He repeated a quote from Faulkner.'
Odd.
