Answer:
5. italianos
6. azules
7. mucha
8. tu
Explanation:
5. In the sentence it is saying that they have lots of cousins but in masculine, so you cannot use the first option, the second option is singular and the sentence is plural.
6. Ojos(eyes) is plural so it cant be grande and modern is not an adjective you would use to describe eyes.
7. pimienta is feminine so the first option would have to be "poca", "cuánto" is used in questions.
8. You use "su" when you are talking about a third person. In this case, you are asking Alfredo who his best friend is so not a third person.
