Final answer:
The author includes paragraphs 14-16 to show how McDonald's serves as a community space, facilitating diverse interactions and connections among people, which are core elements of the McDonaldization concept.
Step-by-step explanation:
The author's most likely purpose for including paragraphs 14-16 is to illustrate how McDonald's functions as a community space where diverse interactions take place. These paragraphs likely describe examples of the kinds of people who visit McDonald's and share the kind of exchanges that occur, highlighting the role of McDonald's as more than just a restaurant, but a place where various segments of the community come together. By showcasing these interactions, the author probably aims to support the argument on the social role McDonald's plays in the concept of McDonaldization, which refers to the principles of the fast-food business model being applied to other social institutions and includes efficiency, predictability, calculability, and control.
