Question

Why does international trade require a system for exchanging currency?

Answer 1

The answer would be A. Process of elimination indicates that answer B is wrong because if they do not do business with other countries then they are not in the trade system. Answer C is incorrect because it involves countries not taking currency from other countries which contradicts the purpose of an international currency exchange system. Finally, letter D is incorrect because while it makes sense, it is arrogant and completely irrelevant since they can not use other countries currency in their home country anyway due to the different values.

Answer 2

I believe it is A.) Countries involved in trade may have different currencies.
