Spanish language Q&A Forum

My boyfriend is from Mexico and he says it should be "siempre cuando", and not siempre que, he said siempre que sounds like I am saying " we will hire the new teacher always when we have the budget" and not as long as we have 

In the test section it says: "Los profesores ___ con los padres de los alumnos"

I thought that should be 'charlaron' because it is an action in the past which has been completed but the system says it is 'charlaban'. 

Please explain?

In the kwiz, I got:

¿Vive aquí ________ Julia Pérez? Tengo un paquete para ella.

as I saw both first name and last name, according to the lesson, I used 'la doña'. I quote:

We use "don" and "doña" in a very similar way to the titles señor/señora. In English these are also the equivalent of Mr. or Mrs. but with the difference that we use them followed by the person's first name or followed by both first name and surname, but never just their surname.

The example even shows: Hemos otorgado el premio a don Javier Cuevas.

Yet, the answer tells me it should have been 'la señora', while in the lesson, no example is to be found stating the combination of 'la señora' (or el señor for that matter) followed by both first and last names.

Is the kwiz wrong here, or am I still missing a clue?

Why is 'peli' not accepted in place of películas?

Why do the pronouns that refer to the grandparents collectively switch between "les" and "los" in the text? For example: "Los visito siempre que puedo y nunca les he visto tan felices en mi vida."
