explain how to solve this

Is the following statement true or false? The action "hold" in the following Clingo program is non-deterministic % File: pendulum Ip % sorts and object declaration boolean(t.). % effects of hold right(T . 1) . hold(T), right(T) len(T+1) :- hold(T), leh(). %% by default, pendulum changes the position (left(T+1)) :- right(T), T=0..m-1. (right(T+1)1 3- left(T). T=0..m-1. % fluents are exogenous initially 1 (right(0)Jenjoy}1. %% uniqueness and existence of values for fluents - not 1 (right(T)Jon(T))1, T-1.m % exogenous action (hold(T)) - T=0..m-1
