Answer:
1. Cotton Gin: In colonial times, cotton cloth was more expensive than linen or wool because of the extreme difficulty of separating seed from the clinging fibers. One man could pick the seeds from only about 1 pound of cotton fiber per day.
2. Reaper/Binder: Small grains had been harvested by hand for centuries, cut with sickles or scythes, hand-raked and tied into sheaves. Grain harvesting machines first appeared in Great Britain in about 1800, and in the U.S. a decade or two later, but most failed. Obed Hussey and Cyrus McCormick developed successful reapers during the 1830s.
3. Thresher: When grain was being cut by hand, the method for separating the kernels from the straw was equally slow and labor intensive. Grain was hauled to a barn where it was spread on a threshing floor and either beaten with hand flails or trampled by animals. That knocked the kernels free of the straw, which was then raked away. The remaining mixture was winnowed by tossing it into the air where the wind was relied upon to blow the chaff and lighter debris away from the heavier grain, which fell back onto the threshing floor.
4. Combined Harvester-Thresher: By the 1920s the steam traction engine was on it's way out, but it paved the way for the gasoline tractors that followed.

Driving while black
Explanation:
Driving While Black is a term used in contemporary U.S. vernacular.
Driving while black refers to the act of African American car drivers being racial profiled. It means that a police officer will stop a motorist solely because of racial bias, rather than any apparent breach of traffic law.
This occurs when police use traffic violations as an pretext to arrest African-Americans who have committed no crime, interrogate them, and search them and their cars. In these situations, police arrest the black drivers without the normal probable cause or reasonable suspicion provision.
