TRUE -Verbs with infinitives ending in –ir form a third group of regular verbs, often called third conjugation verbs. To form the present tense conjugations of these verbs, drop the –ir from the infinitive and add the third conjugation endings (-o, -es, -e, -imos, -en) to the resulting stem.
Answer: lo
Eduardo: ¿Compraste el libro para Mateo? Fernando: Sí, lo compré.
Translation:
Eduardo: Did you buy the book for Mateo? Fernando: Yes, I bought it.
Explanation: "Comprar" is a transitive verb and needs a direct object to complete its meaning. If we want to replace a direct object with its pronoun, it has to agree in gender and number with the direct object.
Since the direct object in this sentence is "el libro", which is a masculine and singular noun, the direct object pronoun is "lo". Lo compré.
