Which machine, invented by Eli Whitney in 1793, quickly and efficiently removed seeds from cotton fibers?

• A. The Cotton Gin
• B. Telegraph
• C. Spinning Jenny
• D. Power Loom

Answer: (A)

A device that quickly and efficiently removes seeds from cotton fibers is being described. Eli Whitney's cotton gin, created in 1793, performs that task by using rotating parts to pull cotton fibers through a mesh while seeds are snagged and expelled. This markedly sped up the process, turning a slow, labor-intensive job into something much faster and more scalable, which had a huge impact on cotton production and the textile industry.

The other inventions listed serve different purposes: the telegraph facilitates long-distance signaling, the Spinning Jenny increases the number of threads spun at once, and the Power Loom speeds up weaving. None of these remove seeds from cotton, so the cotton gin is the correct one for this function.
