Answer and Explanation:
I'll provide an answer against the statement "The fast-food industry can give valuable work experience to teenagers.”
The fast-food industry is not at all concerned with the value the experience of working in it will add to someone's life. As was stated in the text, they hire teenagers "because they are less expensive to hire than adults, but also because their youthful inexperience makes them easier to control." The experience those workers will acquire from that job is limited, probably even useless in other areas.

They have machines beeping all around them, letting them know when the food is supposed to be ready.
