B) If the sets have the same weight, make the representative of the second argument point to the representative of the first argument.

C) The universe of elements is the integers 0 - 16:

a) Union( 3, 5 )        b) Union( 1, 7 )
c) Union( 3, 6 )        d) Union( 8, 9 )
e) Union( 1, 8 )        f) Union( 3, 10 )
g) Union( 3, 11 )      h) Union( 3, 12 )
i) Union( 3, 13 )       j) Union( 14, 15 )
k) Union( 16, 0 )      l) Union( 14, 16)
