2. OFFICIATING/
HAND-SIGNALS

3.  In basketball, an official is a person who
has the responsibility to enforce the rules
and maintain the order of the game. The
title of official also applies to the scorers
and timekeepers, as well as other
personnel that have an active task in
maintaining the game. Basketball is
regarded as among the most difficult
sports to officiate, due to the speed of
play and instantaneous judgement
required.
