<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">mindless followers</span>' is the definition.<br/ ><span class="explanation-format__explanation">(sheep can mean an unquestioning follower)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for sheep that I've seen before include "Ruminant animal" , "Animals said to lack initiative" , "Source of lamb" , "Farm animals" , "Easily led people" .)
