Answer 2

American inventor Eli Whitney (1765–1825) designed the cotton gin (a machine that separates raw cotton fibers from their seeds) after he visited a Georgia plantation and observed the difficult process of separating seeds from fibers on the cotton boll (flower). Cleaning cotton was therefore a time-consuming process that made cotton growing too expensive to be profitable.
