Answer:
The verb form that correctly completes the conversation is:
- Pedro: ¿Qué libro compraste en la librería?
- Luis: Yo compré un libro de historias de ficción.
Step-by-step explanation:
The translation of the sentences in the conversation are:
- Pedro: What book did you buy in the bookstore?
- Luis: I bought a book of fiction stories.
The verb "comprar" conjugated in Simple Past depends on the personal pronoun that modifies its conjugation, to understand this, next I will show you the possible conjugations depending on the personal pronoun that is used:
- Yo compré.
- Tú compraste.
- Él compró.
- Ella compró.
- Ello compró.
- Nosotros compramos.
- Ellos compraron.
As you can see, despite the multiple forms that the verb can have in the simple past, the conjugation that applies to the personal pronoun "yo" is "compré".
