Question

Yusef wants to do a study on how students behave in school when there is a teacher and another adult in the classroom. How can Yusef observe the behavior?

B. By first watching how students react when there is one adult in the classroom and then observing how they react when there are two
C. By interviewing teachers to find out if they prefer to have one or two adults in the classroom at a time
D. All of the above

Answer 1

B. By first watching how students react when there is one adult in the classroom and then observing how they react when there are two

Choice A and C only have to do with what you prefer, not necessarily how you behave. Therefore A, C and D are incorrect.

Answer 2

B. By first watching how students react when there is one adult in the classroom and then observing how they react when there are two

Step-by-step explanation:

The best way to conduct a social experiment is by testing the group of people with whom you are doing the experiment, by observing how they beheave when there´s just the teacher he has a sample, and then he can compare it to how they beheave when there´s two adults.
