Answer:
A group of students having a meeting to plan the prom
Step-by-step explanation:
The answer “a stranger giving another stranger directions in a city” is not the right answer. This is only a small question that does not lead to a formal discussion.
The answer “friends deciding which activity to do for the weekend” is incorrect. This is casual talk among friends.
Answer “a group of students having a meeting to plan the prom” is the correct answer. Formal discussion is led in a guided focus group, based on the series of topics and questions that are formed before the meeting. When a group of students gathers to discuss the prom night, this is in an organized environment in which a coordinated group talks on the pre-formed topic.
The answer “classmates discussing the results of last night's big game” is not the correct answer. This is an informal talk without a scheme.
