Question

If 200 people have been working on developing a new community that will feature houses and small businesses, what will happen to the PPC of the community if 100 people withdraw from developing the community?

the PPC will shift to the left
the PPC will not change
the PPC will become steeper

Answer 1

Answer:

the PPC will shift to the left

the PPC will shift to the left

The manpower (available labor) of the community has been cut in half. This will reduce the greatest possible output for the community, which constitutes a shift to the left for the PPC.
