The final part of the question asks you to explain why the opportunity cost of increasing potato production by 200 pounds is different when you're producing 200 pounds of potatoes versus 800 pounds. We will start this question with the graph from part C, which will allow us to see that as Atlantis continually increases potato output by 200 pounds, it will result in giving up producing more and more pounds of fish.

The section, F, E, is highlighted.
(Speaker)
As Atlantis shifts resources away from producing fish into producing potatoes, they will give up a small amount of fish, but gain a relatively large amount of potatoes. At the other end of the extreme, as Atlantis shifts completely into producing potatoes, it will give up a relatively large amount of fish.

Now the section, B, A, is highlighted.

As Atlantis increases potato production from 800 to 1000 pounds, they must give up 300 pounds of fish. As the island grows more and more potatoes, you have to use less and less suitable land to do so. This highlights the concept of increasing opportunity costs, which means you have to divert increasingly more resources away from fishing as you grow more potatoes. You can produce increasingly less fish for every potato you give up. This implies, of course, that the production possibility frontier becomes steeper the farther you move along it to the right. That is, the production possibility frontier is bowed out. This shows that as the economy increases their production of potatoes, they must give up an increasingly more amount of fish, which is the definition of increasing opportunity cost.
