Final answer:
The correct response to the fill-in-the-blank question is 'maker; pay', as the maker of a note is responsible for paying the instrument unconditionally.
Step-by-step explanation:
The question pertains to the actions required for the unconditional negotiation of a negotiable instrument, such as a promissory note or check. A maker of a note is required to pay the instrument without reservations of any kind. This means that the individual or entity that has promised to pay the amount specified in the note (the maker) is responsible for the payment when the note becomes due, without placing any conditions on the payment.
Thus, the correct fill-in-the-blank response is: A maker of a note is required to pay the instrument without reservations of any kind.
