Question

as a result of the smoot-hawley tariff,
shantytowns were being built across the country.
foreign countries refused to buy american goods.
the bonus army protested in washington, dc.
loans were created to help railroads, banks, and other businesses.

Explanation:

The Smoot - Hawley Tariff Act raised U.S. tariffs on imported goods. In response, foreign countries imposed retaliatory tariffs on American goods, leading them to refuse to buy American goods. Shantytowns were a result of the Great Depression's economic hardship, the Bonus Army protest was about World War I veterans' bonuses, and the loans for businesses were part of government relief efforts, not directly from the tariff.

Answer:

foreign countries refused to buy American goods.
