Question

read the excerpt from fast food nation. cooking instructions are not only printed in the manual, they are often designed into the machines. a mcdonalds kitchen is full of buzzers and flashing lights that tell employees what to do. the evidence presented in this excerpt best supports the authors claim that mcdonalds is the leader in fast food innovation. fast food restaurants use technology designed to reduce the need for skilled labor. technology has helped improve the fast food industry. the workers limited skills have forced fast food employers to rely on machines instead of people

Explanation:

The excerpt mentions that cooking instructions are designed into machines (buzzers and flashing lights tell employees what to do). This implies that technology is used to guide employees, reducing the need for them to have extensive cooking skills. Option 1 about McDonald's being a leader in innovation is not directly supported by the focus on technology replacing skill - based labor. Option 3 about technology improving the industry is too broad. Option 4 wrongly implies that workers' skills force the use of machines; the text shows that the machines are designed to reduce the need for skills.

Answer:

fast food restaurants use technology designed to reduce the need for skilled labor.
