Answer:
The correct indirect object pronoun that completes the conversation is:
- Ramón y su madre siempre ayudan a los muchachos del colegio. Para esta fiesta <u>le</u> enseñó a Josefina y a Pablo a preparar su pollo especial.
Explanation:
Indirect object pronouns depend on the personal pronoun to which they apply, however, since the second sentence of the paragraph has no noun, it can be identified by the verb it contains, the verb in that sentence is <em>"enseñar"</em>, whose conjugation in the Past Tense for each personal pronoun is:
1. Yo enseñé.
2. Tú enseñaste.
3. Él <u>enseñó</u>.
4. Ella <u>enseñó</u>.
5. Ello <u>enseñó</u>.
6. Nosotros enseñamos.
7. Ellos enseñaron.
As you can see, the possible personal pronoun options are <em>él</em>, <em>ella</em> or <em>ello</em>, and since Ramon and his mother had been mentioned, it is reduced to <em>él</em> or <em>ella</em>, and since the indirect object pronoun that most applies is <u><em>"le"</em></u>, it is the one used within the sentence.
