Answer:
1. Mi tía es mexicana. Vive en Guadalajara.
2. Mi primo no es rubio, es moreno.
3. Mi novio cree que la clase no es fácil, es difícil.
4. Los libros son interesantes; me gustan mucho.
Step-by-step explanation:
All the underlined words and expressions tell us what we should put in the gaps.
1. Guadalajara is a city in Mexico. As tía is feminine, we must change mexicano to mexicana.
2. The opposite of rubio (blonde) is moreno.
3. The opposite of fácil (easy) is difícil.
4. Me gustan mucho (I like them a lot) is a positive comment, so the adjective should also be positive: interesantes. We add an -s because los libros is plural.
