5.11 Proof: The police rule out Julius, the wellknown twohundred and fifty pound
burglar because nobody carrying that much weight with themselves could fit through a
small bathroom window, and Julius would not be able to stabilize himself on a ladder in
order to fit yet another window on the second floor.
Somebody of his stature would have
a better chance of breaking into a household by force and as the house shows no signs of
forced entry, Julius the twohundred and fifty pound burglar is ruled out of the equation.
5.15 Proof: In order to prove that Smaller(b, c), we look at the premises.
The first two
premises have to do with b and c being different shapes, thus meaning that they cannot be
identical.
As a result, it is proven that either c is larger than b or else they are both
identical.
The third premise states Larger(c, b)
c = b.
Thus, the first of the or
∨
statement must be true because the latter part of the or statement does not work since c
and b are not identical.
Inversely, Larger(c, b) also means Smaller(b, c).
This is the end of the preview.
