47.

increases in output can only occur in the machine industry.
c.In order to increase food production in these circumstances without reducing machine
production, the economy must reduce inefficiencies.
d.The technological advance reduced the amount of resources needed to produce 47
machines, so these resources could be used to produce more food.
