6. My mom ______ (not cook) dinner at the moment.

Explanation:

The phrase 'at the moment' signifies an action that is not happening right now, indicating the need for the present continuous tense in its negative form.

Solution:

The negative present continuous is formed with 'is not' or 'are not' followed by the present participle of the main verb.

1. Subject: My mom (third person singular)
2. Auxiliary verb: is not (isn't)
3. Main verb: cook + -ing = cooking

Answer: is not cooking
