A:
The problem is that "the very next instant" doesn't exist. So far as we currently know, time is a continuous parameter, represented by a real number. There is no "very next" for real numbers. Say you wanted to pick the "very next number" bigger than 0. Pick one. Then look at half of it. Whoops, that's closer. So no pick can be right.
