Question

how did eli whitney’s invention of interchangeable parts increase manufacturing in the north? (choose 2)

□ allowed workers to work fewer hours

□ enabled people to change an individual part on a product

□ lowered the prices on products enabling more people to purchase

□ forced southern cities to follow suit to compete

Explanation:

1. Analyze "Allowed workers to work fewer hours": Interchangeable parts improved manufacturing efficiency, but there's no direct link to reducing work hours as a way to increase manufacturing. So this is incorrect.
2. Analyze "Enabled people to change an individual part on a product": Interchangeable parts mean parts are standardized, so if a part breaks, it can be replaced easily. This reduces downtime in production and makes repairs easier, which helps increase manufacturing. So this is correct.
3. Analyze "Lowered the prices on products enabling more people to purchase": By making production more efficient (since parts can be mass - produced and replaced easily), the cost of production decreases. Lower prices lead to higher demand, which in turn drives more manufacturing to meet that demand. So this is correct.
4. Analyze "Forced southern cities to follow suit to compete": The question is about how the invention increased manufacturing in the North, not about the South's response. So this is irrelevant.

Answer:

B. Enabled people to change an individual part on a product
C. Lowered the prices on products enabling more people to purchase
