<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">set down</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >'<span class="explanation-format__original">log</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I know that log is a kind of record)</span><br/ ><br/ ></span>
(Other definitions for record that I've seen before include "a hole in one?" , "Facts known about a person - may be criminal" , "release" , "A minute" , "Written report - best so far!" .)
