As you did not provide the script for the audio or any farther information, I think you are referring to the " present progressive audio" so the sentences would be the following:
1 Profesor: Jose Luis está enseñando fisica
2 Botones: Manuel está llevando el equipaje de los huéspedes.
3- Inspector de Aduana: Carlos está pidiendo los pasaportes a los viajeros
4 Estudiante: Yo estoy dibujando el paisaje.
* it is not clear if a student is related to art. This sentences can be also associated to "Artist" as a profession.
