Which factor directly contributed to the growth
of suburban communities after world war ii?
(1) mass transit systems closed.
(2) property taxes were eliminated in many
towns.
(3) returning veterans created a demand for
housing.
(4) widespread mortgage foreclosures caused
farmers to leave rural areas.

A factor directly contributing to the growth of suburban communities after World War II was that 3. returning veterans created a demand for housing. These veterans returned home with the GI Bill, which guaranteed them low-interest loans enabling them to easily purchase homes. However, that required that the homes first exist and thus many were built in suburban communities to satisfy this demand.
