Final answer:
The correct words to fill in the blanks are 'allowed' and 'aloud,' So the complete sentence should read: 'Elementary school students are not allowed to talk while the teacher reads aloud after lunch.' (Option D).
Step-by-step explanation:
The question you have asked is related to the correct usage of homophones, which are words that sound the same but have different meanings and spellings. In the sentence 'Elementary school students are not ____________ to talk while the teacher reads __________ after lunch,' the correct words to complete it are 'allowed' and 'aloud.' So the complete sentence should read: 'Elementary school students are not allowed to talk while the teacher reads aloud after lunch.'
Thus, the correct words to fill in the blanks are 'allowed' and 'aloud,' as they fit the context of the sentence regarding permission and speaking out loud. The word allowed means to give permission, while the word aloud means in a voice that can be heard.
Thus, the correct option is D.
