Answer :

The cotton gin made cotton farming more profitable and increased slave labor demand. Both the cotton gin and sewing machine boosted the textile industry. Interchangeable parts allowed for mass production, and Samuel Morse invented the telegraph, enhancing communication. Therefore, the correct options are 1- D, 2- B, 3- C, 4- D, 5- B.

1) The correct answer is D) The cotton gin made growing cotton very profitable and increased the demand for slave labor. The cotton gin, invented by Eli Whitney in 1793, significantly sped up the process of removing seeds from cotton fibers. This made cotton farming much more profitable and, unfortunately, also led to an increase in the demand for slave labor to meet the growing industry's labor needs.

2) The correct answer is B) Textile. Both the cotton gin and the sewing machine were pivotal innovations that greatly enhanced the efficiency and productivity of the textile industry.

3) The correct answer is C) They imported technological advances from Great Britain. Both Lowell and Slater were instrumental in bringing British industrial technologies to the United States, significantly advancing the American textile industry.

4) The correct answer is D) Interchangeable parts. Originally developed by Eli Whitney, interchangeable parts allowed products to be manufactured more rapidly and efficiently, leading to the mass production of goods.

5) The correct answer is B) Samuel Morse. Samuel Morse invented the telegraph and Morse code, which revolutionized long-distance communication in the United States and around the world.
