Which statement is true?

A) Every nation should try to be completely self-sufficient.
B) International trade lowers our standard of living.
C) The basis for international trade is specialization.
D) Importing consumer products increases our prices.

The basis for international trade is specialization, which allows countries to focus on producing the goods and services where they have a comparative advantage, and then trade with other countries for the goods and services they need but cannot produce as efficiently.

Answer: None of the other options are true. A is not true because complete self-sufficiency is unlikely and can impede progress and innovation. B is not true because international trade can provide access to goods and services that may not be available domestically, and can increase efficiency and productivity. D is not true because importing consumer products can actually lower prices by increasing competition and providing consumers with more options.
