I believe the answer is:

<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">part</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know that section is a kind of part)</span><br/ ><br/ >'<span class="explanation-format__original">division</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I know that section is a type of division)</span><br/ ><br/ ></span>
(Other definitions for section that I've seen before include "surgical procedure" , "Division, portion" , "Distinct part" , "Department, division" , "Divide; part" .)
