Which fruit rots the fastest?

Well, it's actually sort of tied between a banana and a pear. The banana definitely becomes black faster, but it sort of slows down rotting and the pear "out-rots" the banana. The pear would start rotting, and it'll be gushy. It becomes completely gushy and the juice runs out of it within 3 days. The banana however, will slow down and become a little blacker (or browner) day by day.

*I observed this with the fruit cut in half, wrapped in plastic wrap, and on a window sill under the sun.
