Explanation:

These are Spanish grammar exercises that require replacing the underlined subjects with the correct subject pronouns.

1. "Sus padres" (their parents) is a plural third-person subject, so we use the pronoun "Ellos".
2. "Tú y Ana" (You and Ana) is a plural second/third-person subject, so we use the pronoun "Ustedes".
3. "Nuestra madre" (Our mother) is a singular feminine third-person subject, so we use the pronoun "Ella".

Answer:

1. Ellos viven en España.
2. Ustedes hablan mucho.
3. Ella es azafata.
