Psmith, the TeX bot, in fixed font mode:
Does Santa Claus exist?
There is not a unique computable answer to that question. Possible answers include:
a) Santa Claus is as real as you wish him to be; if you believe in Santa, then he is real.
b) Saint Nicholas is the common name for the real person Nicholas of Myra, a saint and historical Bishop of Myra.
c) Santa gives gifts to children, therefore he is.
