Question

which excerpt from fast food nation best states a reason supporting the authors claim that fast food restaurants follow the assembly line model?

once an order has been placed, buttons light up and suggest other menu items that can be added.
at burger king restaurants, frozen hamburger patties are placed on a conveyer belt and emerge from a broiler ninety seconds later fully cooked.
the mcdonalds operations manual today has ten times the number of pages and weighs about four pounds.
teenagers open the fast food outlets in the morning, close them at night, and keep them going at all hours in between.

Explanation:

To determine the correct excerpt, we analyze the assembly line model, which involves a sequential, automated process for production. The option about Burger King's frozen patties on a conveyor belt (cooked in 90 seconds) directly shows a step - by - step, conveyor - based production process, matching the assembly line model. The other options: the first is about menu suggestions, the third about a manual's size, and the fourth about teenage workers, none of which relate to the assembly line production process.

Answer:

At Burger King restaurants, frozen hamburger patties are placed on a conveyer belt and emerge from a broiler ninety seconds later fully cooked.
