Commentator: The theory of trade retaliation states

       that countries closed out of any of another

       country’s markets should close some of their

       own markets to the other country in order to

       pressure the other country to reopen its mar-

       kets. If every country acted according to this

       theory, no country would trade with any other.

   The commentator’s argument relies on which of the

   following assumptions?

   (A) No country actually acts according to the theory

       of trade retaliation.

   (B) No country should block any of its markets to

       foreign trade.

   (C) Trade disputes should be settled by international

       tribunal.

   (D) For any two countries, at least one has some

       market closed to the other.

   (E) Countries close their markets to foreigners to

       protect domestic producers.
