Answer 2

Table no. 13 is reserves for Mr. Shelby.

Step-by-step explanation:

When being assertive you are speaking in a more direct way while being honest, but in a respectful manner. When speaking in a more assertive tone you will come off as more self-confident instead of making everything you say sound like a question.

If you are trying to make a sentence sound more assertive avoid things like question marks, and uncertain tones.
