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?

From the examples given it's hard to tell why a native speaker would choose one of these adverbs in preference to another one in any given situation. Is there any guidance on this? Why would I choose 'igual' over 'lo mismo', for example, if they both mean the same thing?  

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?

I thought the past participle of leer is leído. But the above example uses leídas. I have no knowledge of conjugating past participles. Please explain the usage. Thanks 

Hola,

'Estamos a 28 de diciembre' should also be considered correct here, right?

I noticed in the given examples in the lesson for estar to talk about dates, that 'estamos a' is always followed by a date written in words. Is it acceptable to use 'estamos a' followed by a date in digits?

Thanks,

Benhur

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."
