I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">took on</span>' is the definition.<br/ ><span class="explanation-format__explanation">('assume' can be a synonym of 'take on')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for assumed that I've seen before include "Took upon oneself" , "Taken as true; adopted" , "Affected; supposed" , "Bogus" , "Put it on - without being told?" .)
