What? I don't get what this question is asking.
The answer would be an argument.
The grammar for this is confusing, since I would say, for example the first one, played. But this would be: play, rides, read, sleep, study, works, cooks, speaks, sings, dances. It’s a bit confusing. For the my dad work/works one, it would be works because he is doing it. If we were to use work for this, then it would be something like, “My dad goes to work everyday.” Hope this helped a bit
