Which invention by Eli Whitney in 1793 separated cotton fibers from seeds, increasing production and the demand for enslaved labor?

• A. Spinning Jenny
• B. Cotton Gin
• C. Seed Drill
• D. Mechanical Reaper

Answer: (B)

Technology that speeds up crop processing can drastically shift labor demand. The cotton gin, invented in 1793, uses a hand-cranked mechanism to pull cotton fibers away from seeds much faster than by hand. This huge boost in processing speed made cotton production far more profitable, especially in the Southern states. As cotton became a dominant crop, plantation owners expanded fields and needed more enslaved labor to plant, tend, pick, and gin even more cotton. The machine didn’t just process cotton faster; it helped intensify the system of slavery that supported cotton’s profitability.

Other inventions listed do different jobs: the Spinning Jenny speeds up turning fiber into yarn, not removing seeds from cotton; the Seed Drill helps plant crops efficiently, not separate cotton fibers; the Mechanical Reaper is used for harvesting grain.
