Explanation:

A tariff is a tax on an imported good. Tariffs increase the price of foreign goods. These tariffs are usually implemented to protect American businesses, as it makes American consumers more likely to buy American goods since they are cheaper than foreign goods. This strategy has been used several different times throughout US history, including during the 1920's.
