Answer: The right answers are:
1. lo
2. la
3. las
4. las
5. los
Explanation: Just to elaborate a little on the answer, it can be added that in this exercise they are asking you to complete the answer to each question with the appropriate personal pronoun in the accusative case. For instance, in the first sentence it is said "Do you have your notebook? No, I don't have." In order to better complete the sentence, it should say "No, I don't have it." In Spanish, the pronouns also have a gender, so, if the word is masculine, like "cuaderno" or "aviones," the pronoun will agree with it ("No, no lo tengo" and "Sí, los mira").
