The right answer is- D- el director
Ellas (ensenan) Administracion de empresas. Yo (necesito) preparer la tarea. Hector y yo (compramos) en la libreria. Me (gusta) bailar los sabados. Enrique (desea) escuchar musica. A ti te (gusta) la psicologia?
You can fill it by two ways:
Ellas PELAN los cocos
Ellas ROMPEN los cocos
No hay nada encima de la mesa. If you sound it out, it could either be "nada" or "nadie" but if you are talking about an object, then use "nada". If you are talking about someone not on the table, you would use "nadie" Nada: for object, Nadie: for person.
Hope this helped
