Leo: Given the sentence "Man with long black hair using a mic in the midst of a musical performance as the crowd watches." is it true that "A man is attempting to do karakoe."?
Mei: OK, So, let's think first...
Me:
Man with long black hair using a mic in the midst of a musical performance as the crowd watches does not imply that he is attempting to do karakoe.
Thus, the answer is it is not possible to tell.
