Which excerpt from fast food nation best states the author’s overall claim? the fast food industry’s obsession with throughput has altered the way millions of americans work, turned commercial kitchens into small factories, and changed familiar foods into commodities that are manufactured. unlike olympic gymnastics—an activity in which teenagers consistently perform at a higher level than adults—there’s nothing about the work in a fast food kitchen that requires young employees. although richard and mac mcdonald introduced the division of labor to the restaurant business, it was a mcdonald’s executive named fred turner who created a production system of unusual thoroughness and attention to detail. teenagers have been the perfect candidates for these jobs, not only because they are less expensive to hire than adults, but also because their youthful inexperience makes them easier to control.
