Which option correctly reflects the purpose of the 16th Amendment?

• A. Direct election of Senators
• B. Federal income tax
• C. Prohibition of alcohol
• D. Women's suffrage

Answer: (B)

The main idea being tested is the federal government’s power to tax income. The 16th Amendment explicitly authorizes Congress to levy a tax on incomes without having to apportion it among the states or respect population counts. This change fixed a constitutional obstacle created by earlier court decisions that had said income taxes had to be apportioned by state population, which made a national income tax impractical. Historically, this amendment came in the wake of the Progressive Era’s demands for more federal revenue to fund reforms and programs. It solidified a reliable source of national funding beyond tariffs and excise taxes. It also addressed the Supreme Court’s ruling in Pollock v. Farmers’ Loan & Trust Co., which had blocked a broad income tax on the grounds that it was a direct tax requiring apportionment. The other options point to different amendments and issues: direct election of Senators came with the 17th Amendment; Prohibition of alcohol is the 18th Amendment; and women’s suffrage is the 19th Amendment. None of those establish the federal authority to tax income.
