Suppose a second nation has the following data. Plot

the PPC, and then determine which nation has the
comparative advantage in which activity. Show
whether the two nations can gain from specialization
and trade.

To determine which nation has the comparative advantage in each activity and whether the two nations can gain from specialization and trade, we first need the data and the production possibilities curves (PPCs) of both nations. Since the data for the second nation is not provided, we cannot directly determine the comparative advantage without the PPC.

The PPC represents the different combinations of goods or activities that a nation can produce efficiently given its resources and technology. Each point on the PPC represents an efficient allocation of resources between two activities. The shape of the PPC reveals the opportunity cost of producing one good in terms of the other.

To plot the PPC, we need the quantity of two activities the second nation can produce under different scenarios or combinations. Once we have the PPC, we can identify the comparative advantage and determine whether both nations can benefit from specialization and trade.

Therefore, without the specific data for the second nation, we cannot accurately plot the PPC or determine the comparative advantage and potential benefits from specialization and trade.
