To improve the efficiency of the international monetary system, the author supports (A) increasing the world's gold supply (B) setting limits on the amount of money being exchanged (C) lowering tariffs between nations (D) creating a single worldwide currency (E) reducing transaction costs A B C D

D

This question revolves around the author's suggestion for improving the effectiveness of the international monetary system. To answer this question, a clear understanding of these each options and their impact on the efficiency of the international monetary system is needed.(A) Increasing gold supply- More gold reserves could potentially strengthen the currency backed by it, offering stability but not necessarily increasing the efficiency of IMS. (B) Setting limits on exchange- This could potentially affect trade negatively, by controlling supply of capital. However, purposely manipulating money exchange isn't a regular means of enhancing the system's efficiency. (C) Lowering tariffs between nations- The term tariff refer to the taxes imposed on goods and services imported from other nations. Reduced tariffs could promote trade, but don't seem to target international monetary system in any special way. (D) Creating a single worldwide currency- This solution could help integrate global economies, bypass exchange rates problem and more efficiently address global issues. It, however, could also raise problems (like reduced national sovereignty). But in terms of effectiveness of IMS, it appears most practicable among options.(E) This would involve expediting or cheapening the process of completing transactions. Reduced costs indirectly make a system more efficient, but it is typically the effects and not an alteration to the inherent structure of the system. In light of these examinations, author's most likely suggested way is choice (D): developing a single global currency. Denn it gives a direct way for improving international monetary systems with fewer steps or complexities than other options.
