Answer 1

, leading to increased productivity and economic growth. The use of interchangeable parts, pioneered by innovators such as Eli Whitney in the early 19th century, revolutionized manufacturing by allowing for mass production of standardized components that could be easily replaced if damaged. This in turn created a need for a patent system to protect the intellectual property of inventors and incentivize further innovation. As a result, the development of interchangeable parts paved the way for the modern manufacturing industry and significantly impacted the way goods are produced and distributed worldwide.
