A process chemist compares the atoms supplied by the monomers with the atoms in one repeating unit of each polymer.

Route	Starting molecules	Atoms supplied	Atoms in one repeating unit
A	one alkene molecule	$C3H6\text{C}_3\text{H}_6$	$C3H6\text{C}_3\text{H}_6$
B	one molecule of each of two monomers, both with two functional groups	$C8H16O6\text{C}_8\text{H}_{16}\text{O}_6$	$C8H12O4\text{C}_8\text{H}_{12}\text{O}_4$

The chemist concludes that atom counts cannot be used to distinguish addition polymerisation from condensation polymerisation.

Explain whether the data support the chemist's conclusion. In your answer, identify the type of polymerisation used in each route.
