Javier le presta el abrigo a Maripili
Nosotros les vendemos ropa a los clientes
El vendedor nos trae las camisetas a mis amigos y a mí
An Indirect Object Pronoun is a person that, in indirect way, takes the action of a verb. Sentence using indirect object pronouns tell us to whom or for whom an action is done. So we need to arrange these three sentences in the present tense and using the correct indirect object pronoun. So:
Correct answer: Javier le presta el abrigo a Maripili
Since the action is being performed for Maripili, then we use the indirect object pronoun that matches the third person singular, which is le. On the other hand, Javier also matches the third person singular, so we conjugate the verb prestar matching this person as well.
Correct answer: Nosotros les vendemos ropa a los clientes
Since the action is being performed for los clientes, then we use the indirect object pronoun that matches the third person plural, which is les. On the other hand, we conjugate the verb vender as vendemos because it matches the first person plural (nosotros)
Correct answer: El vendedor nos trae las camisetas a mis amigos y a mí
Since the action is being performed for mis amigos y yo, then we use the indirect object pronoun that matches the first person plural, which is nos. On the other hand, El vendedor matches the third person singular, so we conjugate the verb traer matching this person as well, which is trae.
