Answer:
In this type of problem, it asks about the most logical answer that fits to the subject.
1. ¿Dónde está el padre? Está en el sofá.
2. ¿Dónde está la computadora? Está encima de la mesa.
3. ¿Dónde está la estantería? Está a la derecha del televisor.
4. ¿Dónde está la silla? Está aquí.
5. ¿Dónde está la madre? Está cerca del padre.
So, if a person is the subject, we have to find a logical spot for them. For example, the father and the mother only can be on the couch, they won't be on the table, it doesn't make sense. But, the computer actually is on the table, because there is where commonly belongs.
So, each answer is according to what is normal.
