<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">shrug</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know that shrug is a more specific form of gesture)</span><br/ ><br/ >'<span class="explanation-format__original">wave</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(waving is a type of gesture)</span><br/ ><br/ ></span>
