Which act was passed to increase the tax on foreign products to over 48 percent during the Billion Dollar Congress?

The McKinley Tariff of 1890 is recognized for significantly increasing tariffs on foreign products, raising rates to an average of over 48 percent. This legislation was part of a broader economic policy favored by the Republican Party at the time, aiming to protect domestic industries from foreign competition and generate revenue for the federal government. The McKinley Tariff is notable for its impact on trade and for stirring controversy, as it provoked opposition from consumers and businesses that relied on imported goods, ultimately contributing to political shifts in the subsequent elections. Other options do not match the specifics of the question, as they either involved different tariff rates or were enacted in different contexts without reaching that particular tax rate on foreign goods.
