Answer:
3)Many companies in Detroit closed down because they could not compete with Ford.
Explanation:
Henry Ford was an American entrepreneur and mechanical engineer, founder of the Ford Motor Company, and the first entrepreneur to apply the series assembly in order to mass-produce automobiles in less time and at a lower cost. This generated a very large loss for competing companies, which closed down for failing to compete with the Ford Motor Company.
