Roll call calls are a common practice in many organizations, such as schools, businesses, and government bodies. A roll call call is when each person present is asked to state their name or answer in the affirmative. The term 'AYES' refers to those who answer in the affirmative, while 'NAYS' refers to those who answer in the negative. Lastnames refers to the last names of those present. This practice is used to ensure that everyone is present and accounted for.
