the answer is A. Imperfecto progresivo.
The progressive imperfect is used to express something that was taking place in the past. It is formed using the verb to be in past (in this case: estaba) plus the verb ending in ing (ando, endo, in this case: cantando). It is mainly used for: on-going actions that were happening in the past.
The model you gave is a little unclear, but I think it would be:
1) Ricardo voy a preparar su tarea a las ocho y cuarto.
2) Isabel y Ricardo van a cenar a las nueve.
3) Isabel voy a ver la television a las nueve y treinta y cinco.
4) Ricardo voy a caminar con el perro a las diez menos cuarto.
I have 2 answers:
1. Como ellos no tenian tecnologia en esa epoca, ellos podian jugar con juegos de mesa. Tambien ellos podian ir a la escuela para aprender. (Since they didn't have sorts of technology, they could play with board games. Also tey can go to school to learn)
2. (If you are asking for a translation) ¿Qué hacía tu mamá o papá cuando él o ella tenía cinco años? = What did your mom or dad do when he or she was five years?
Hope this is helpful
