Of these three choices-tariffs, quotas, and free trade-economists like the most and the least. a) tariffs, quotas d) free trade, quotas b) tariffs, free trade e) quotas, free trade c) free trade, tariffs f) quotas, tariffs

Before choosing the answer, let's briefly go over the concepts involved: 1. Tariffs: These are taxes imposed on imported goods, which increase their price and make them less competitive compared to domestically-produced goods. This can lead to reduced demand for imported goods, protection of domestic industries, and increased government revenue. 2. Quotas: These are restrictions on the quantity of certain goods that can be imported into a country. Quotas are meant to protect domestic industries by reducing the competition they face from imported goods. 3. Free trade: Free trade is a policy that eliminates tariffs, quotas, and other barriers to trade between countries, allowing goods and services to move freely across borders. Economists often argue that free trade leads to increased efficiency, economic growth, and benefits for consumers through lower prices and increased choices.

Now let's examine the given choices and determine the most and the least favored concepts among economists: a) tariffs, quotas d) free trade, quotas b) tariffs, free trade e) quotas, free trade c) free trade, tariffs f) quotas, tariffs

Economists typically prefer free trade because it allows for the most efficient allocation of resources and promotes economic growth. Therefore, we should look for the choice where "free trade" is listed as the most preferred concept. In this case, choice "c" has free trade as the most preferred option.

Now, we need to determine which concept economists like the least. Between tariffs and quotas, economists generally dislike quotas more as they create stronger distortions in the market and limit consumer choices. Thus, combining these preferences, the answer should be the choice where the least preferred option is quotas. Referring back to the choices, we can see that choice "c" (free trade, tariffs) represents the most and the least preferred concepts among economists. Final Answer: c) free trade, tariffs
