What does increasing the number of laborers in an economy generally cause? a decrease in the production possibilities curve a decrease in the opportunity cost of production an increase in the opportunity cost of production an increase in the production possibilities curve?

When there is an increase in the number of laborers in an economy generally there is an increase in the production possibility frontier (curve). 

The production possibility frontier which is also known as the PFF is a curve that shows maximum output that two possibilities may produce depending on the resources given. Other factors can also be mixed in with this to help predictions. The one thing to remember is that this is a hypothetical situation and it can change based on what items/resources are shifted around.
