Question

What is the subject of the teacher announcement​

Answer 1

Answer:

Make sure what is presented to you is fully understandable.

Explanation:

To announce means you have a full understanding of the lesson and what notice and mistakes you need to avoid. I think without announcements at the beginning of class I wouldn't know what going around the school or class.
