<span class="explanation-format__ClueExplanation">This clue is a double definition.<br/ ><br/ >'<span class="explanation-format__original">applause</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(hand is a kind of applause)</span><br/ ><br/ >'<span class="explanation-format__original">worker</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(hand is a kind of worker)</span><br/ ><br/ ></span>
