Explanation:

In Spanish, when there are two object - pronouns (direct and indirect), the indirect comes first and the direct follows. 'Les' is an indirect - object pronoun and 'las' (for 'postales') is a direct - object pronoun. In sentence 2, 'les' is indirect and 'la' (for 'fruta') is direct. In sentence 3,'me' is indirect and 'lo' (for 'el pollo asado') is direct. In sentence 4, 'te' is indirect and 'lo' (for 'un café') is direct.

Answer:

1. Yo se las envié.
2. Cella se la compró.
3. Ángel me lo recomendó.
4. El camarero te lo sirvió.
