<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">played a role</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for acted that I've seen before include "appeared on stage" , "Worked" , "did something!" , "Played a 30ac" , "took part in simulation" .)
