May someone just help me with the fill-ins at the very top and questions in the middle? *don't mind the last one I’m still working on that*

Answer:
Question 1 (these are options, is there a vocabulary word bank? If so use the similar corresponding word):
(1) I would use the word "gros". "parce qu'il mange beaucoup", means the dog eats a lot. So, a descriptive word for the dog should be fat.
(2) I would use the word "heureux". Because the dog barks at night, the parents are not happy.
(3) I would use the word "intelligent". Because the dog thinks he is human, he could be intelligent.
(4) Enfants (or children) could be described as "petits"
(5) A dog house can be described with colors, so "rouge".
(6) The sisters do not like the dog. So, "enchantés" would work.
Question 2:
(1): Comment-es tu? How are you?
Je suis (fill in the blank with adjectives).
(2): Comment sont tes parents? How are your parents?
Ils sont (fill in the blank with adjectives)
(3): Est-ce que tu aimes les grands familles? Pourquoi? Do you like big families? Why?
You could use: Je n'aime pas les grands familles. (I do not like big families). Ils sont trop fou. (they are crazy).
Or: J'aime les grands familles. (I like big families). Ils sont amusants. (they are fun).
