Answer :
The sentence "Elementary school students are not allowed to talk while the teacher reads after lunch" requires the words "allowed" and "aloud" to complete it correctly. Here's a breakdown of the reasoning:
1. "Allowed" is the correct term here because it means "given permission." In this context, it indicates that students do not have permission to talk while the teacher reads after lunch.
2. "Aloud" is the appropriate choice as it means "with a normal speaking voice" or "vocally." It signifies how the students are not allowed to speak during the specified time.
By using "allowed" to describe the permission aspect and "aloud" to specify how the students should not talk, the sentence is effectively completed, conveying the intended meaning that students are expected to remain quiet during the teacher's reading session after lunch.
