Question

1. how did increased u.s. tariffs in the 1920s help henry ford sell model - ts?

they made spare parts for cars cheaper.
they reduced competition from other nations.
they made bankers richer.
they lowered prices for exports to europe.

Explanation:

Tariffs are taxes on imported goods. Increased U.S. tariffs in the 1920s would make imported cars or car - related products more expensive, thus reducing competition from foreign car manufacturers. Spare parts' cost isn't directly related to tariffs in this way, making bankers richer is irrelevant, and tariffs would raise export prices (not lower) to Europe. So the correct reason is that tariffs reduced competition from other nations.

Answer:

B. They reduced competition from other nations.
