Explanation:

A direct object is that one which is directly affected by the action that the subject of the sentence does. For instance, number one: What is Marcos asking for? the tourist brochure, thus, "folleto turístico" is the direct object and Marcos, who is the subject is the pronoun, in this case refering to "He". In Spanish, pronouns are: Yo, tú, él, ella, usted, nosotros, ellos but also the suffixes -nos, -os and -se. For example, number 2 says "necesitamOS" which means in English we need thus, this is the pronoun because in Spanish that suffix means "we"; same thing with number 8. Number 5 is completely direct as "Ellos" is they.
