What was the primary function of Eli Whitney's cotton gin?

• A. To weave cotton textiles more efficiently
• B. To spin cotton fibers into thread
• C. To separate cotton fiber from seed
• D. To extract cotton oil

Answer: (C)

The key idea here is what a cotton gin actually does. Its primary function is to separate cotton fiber from its seeds. Eli Whitney’s device uses rotating rollers or brushes to pull the fluffy cotton through a tight grate, removing the seeds while leaving the fiber clean. This automated separation converted a slow, labor-heavy step into something much faster, transforming cotton production in the United States. It’s not about weaving cotton into cloth, which requires a loom; it’s not about spinning fibers into thread, which uses a spinning implement; and it’s not about extracting oil from cotton seeds, which is a different process. The cotton gin specifically performs the separation of fiber from seed.
