I believe the answer is:
true
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">factual</span>' is the definition.<br/ ><span class="explanation-format__explanation">(similar in meaning)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for true that I've seen before include "Genuine, actual" , "Straight or correct" , "comfortable" , "not showing 12 [DISHONESTY]" , "Loyal; authentic" .)
