1. The correct answer is four. The answer will always be one less than the number of monomers present in the polymer. You will cleave water from the first, second, third and fourth monomer. The fifth monomer of the chain does not have anything attached to it.

3. XXXX-OH + HO-XXXXXX-OH + HO-XX ----------------------->
reactants (3 monomers)

XXXX-O-XXXXXX-O-XX + 2 HOH
products (1 polymer) water
Note: Two waters were split out (one less water than the number of monomers)

4. XXXX-O-XX-O-XX-O-YYYYN + 3 HOH -------->
reactants (1 polymer) water

XXXX-OH + HO-XX-OH + HO-XX -OH + OH-YYYYN
products (4 monomers)

Note: Three water were required and four monomers were split out.
