Final answer:
Students experience a Silent Listening Period where they are expected to listen without speaking. The manifest function of schools like learning to read and write is a direct outcome of education.
Step-by-step explanation:
During the Silent Listening Period, students go through a phase where they are listening only and may not attempt to answer at all. This reflects an element of classroom management and understanding when to speak up and when to be silent.
Answering the student's question, the correct option is: 3) Silent Listening Period. However, it is important to note that the manifest function of schools, as referenced in the student's question, more broadly relates to the direct and intended outcomes of an educational system, such as option b. Learning to read and write.
