The cotton gin was a machine that revolutionized the cotton industry by automating the process of separating the seeds from the cotton fibers. This innovation significantly reduced the cost of producing cotton as it eliminated the need for manual labor to remove the seeds. Additionally, the cotton gin had the capacity to clean up to 50 times more cotton than could be done by hand, increasing efficiency and productivity in cotton production. The use of standard-sized parts that could be easily changed also made repairs of the equipment faster, further enhancing its effectiveness and reliability.

The correct answer is "changed the way goods were made from hand to machines." This answer accurately summarizes the impact of the Industrial Revolution on the manufacturing process. During this period, there was a shift from manual labor to the use of machines, which significantly increased productivity and efficiency in the production of goods. This change revolutionized various industries and paved the way for mass production.

A free market refers to an economic system where producers of goods and services have the freedom to make decisions on how to allocate resources based on the demand from consumers. In this system, there are no restrictions or interference from the government or any central authority. Producers are able to determine what to produce, how much to produce, and at what price to sell their products or services. This allows for competition, efficiency, and innovation in the market as producers respond to consumer preferences and market signals.

Eli Whitney is known for inventing the cotton gin. The cotton gin was a machine that revolutionized the cotton industry by efficiently separating cotton fibers from their seeds. This invention greatly increased the productivity of cotton production and had a significant impact on the economy of the Southern United States. Whitney's invention made cotton processing faster and more profitable, leading to a boom in cotton production and the expansion of slavery in the South.

Samuel Slater was a British mechanic who played a significant role in bringing the industrial revolution to the US. He achieved this by introducing his yarn spinning machine, which revolutionized the textile industry. The cotton gin, on the other hand, was invented by Eli Whitney, not Samuel Slater. Therefore, the correct answer is that Slater was a British mechanic who brought the industrial revolution to the US with his yarn spinning machine.
