Answer:
They are not all correct. Explanation below.
Explanation:
Numbers 1-6 are all correct as well as number 10.
Number 7: Pierre is a singular person, so the conjugation of "regarder" would be "regarde". "Regardons" is only used for "nous" or "<<nom>> et moi", etc.
Number 8 is talking about two boys, so the conjugation of "regarder" would be "regardent".
For Number 9, for "on" we use the il/elle ending for conjugations, which in this case would be "regarde".
