基本上我整题无从解起，而且我实在找不出1错的理由，
所以想在这边请问各位。
Q13:
For any positive integer x, the 2-height of x is defined to be the
greatest nonnegative integer n such that 2n is a factor of x.
If k and m are positive integers, is the 2-height of k greater
than the 2-height of m ?
(1) k > m
(2) k / m is an even integer.
答案给 B
