Question

1 - escoger audio listen to what people are doing and choose the matching description. es profesor. es estudiante. es botones. es inspector de aduanas.

Answer 1

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.
