What did Eli Whitney invent?

• A. Cotton gin
• B. Interchangeable parts machine
• C. Steam engine
• D. Sewing machine

Answer: (C)

The main idea being tested is identifying which invention is historically linked to Eli Whitney. Whitney is best known for creating a machine that could quickly separate cotton fibers from seeds—the cotton gin. Introduced in 1793, this device used rotating components and comb-like elements to pull cotton through and pluck out seeds, dramatically speeding up a process that had been done by hand. The result was a huge boost in cotton production and profitability in the United States, especially in the South, which in turn had major economic and social consequences, including the entrenchment of slavery in cotton-growing regions. The other items aren’t the invention most closely associated with Whitney. Interchangeable parts refers to his broader impact on manufacturing and standardization, but the cotton gin is the specific invention most people remember him for. The steam engine and the sewing machine are associated with other inventors and moments in history.
