Is the following statement true or false?

The action "hold" in the following Clingo program is non$-$deterministic.

$\%$ File: pendulum.lp

$\%$ sorts and object declaration

boolean$($t;f$).$

$\%$ effects of hold

right$(T+1)$ :$-$ hold$(T,$ right$(T.$

left$(T+1)$ :$-$ hold$(T),$ left$(T).$

$\%$ by default, pendulum changes the position

left$($T$+1)\}$:$-$ right$($T$),T=0..m-1.$

$\{right(T+1)\}$:$-$left$(T),T=0..m-1.$

$\%$ fluents are exogenous initially

$1\{$right$(0)$;left$(0)\}1.$

$\%$ uniqueness and existence of values for fluents

;$-$ not $1\{$right$($T$)$;left$($T$)\}1,$ T$=1..$m$.$

$\%$ exogenous action

$($hold$($T$))$ :$-$ T$=0..$m$-1.$
