1. given this information, the opportunity cost of one computer in france is and the opportunity cost of one computer in the united states is
2. given this information, has a comparative advantage in producing wine and has a comparative advantage in producing computers:
a. the united states; france
b. france; france
c. the united states; the united states
d. france; the united states

I am assuming here that you use the example where in the US the workers can produce 200 computers of 100 cars  and the French workers can produce 80 of each.

 Then the opportunity cost of one computer in France is higher than in the United States -which means that it's lower in the United States (twice as low)

So, France would have a comparative advantage in producing wine and US in producing computers.

Where are the choices.
