Answer:
1. Yo voy al cine el lunes y martes en autobús.
2. Tú vas a la biblioteca en carro.
3. Mi amigo va a la fiesta en tren.
4. Nosotros vamos al centro comercial a pie.
5. Ellas van a Miami mañana también.
Explanation:
1. Cine is masculine, so it would be <em>al</em>.
2. Biblioteca is feminine, so it would be <em>a la</em>.
3. Fiesta is also feminine, so it would use <em>a la</em>.
4. Centro comercial is masculine, so it would be <em>al</em>.
5. Miami is a place that isn't translated to Spanish, making it just <em>a </em>from lack of gender.
