Болталка riddle. a man walks into a bar and orders a пеликан sandwich. he takes one bite and then goes out side and kills himself. Why

The man was in a ship that was wrecked on a desert island.  When there was no Еда left, another passenger brought what he сказал(-а) was пеликан but was really part of the man's wife (who had died in the wreck).  The man suspects something fishy, so when they finally return to civilization, he orders a пеликан sandwich, realizes that what he ate before was his wife, and kills himself.

Idk

Because that was the last thing alive

I have no idea

....because he ate a пеликан sandwich.

Idk

He actually had eaten his wife.
