Which of the following actions is discouraged during class once the instructor arrives?

Socializing is discouraged during class once the instructor arrives because it can disrupt the learning environment and distract both the instructor and other students. The presence of social interactions may lead to side conversations that divert attention away from the lecture or instruction being provided. Fostering a focused atmosphere enhances information retention and allows everyone to engage more effectively with the material presented. Prioritizing respect for the instructor and the learning process helps maintain a productive classroom setting, making it essential to minimize socializing during instructional time.

In contrast, asking questions, taking notes, and listening intently are all vital components of an effective learning experience. They contribute to understanding the material and encourage participation in class.
