Spanish language Q&A Forum

How would I say someone else is doing something to another person and not themselves? Like if my mom is a hair stylist and she's combing someone else's hair.  Like in "Mi madre se peina el pelo con un cepillo nuevo." Would I need to put something like "el pelo de la mujer" or with the personal a like "el pelo a la mujer" 

Why is "Ellos propusieron cambiar la ruta del viaje." wrong?

Why is "Propusieron cambiar la ruta del viaje." the only right answer?

Tu novia y tú habéis estado comprometidos hasta este año.Your girlfriend and you have been engaged until this year.

The meaning is unclear to me — are they no longer engaged?  

Then, in my opinion,  the English should be:

..Your girlfriend and you.were engaged until this year, not have been. But maybe I do not understand what is being expressed in Spanish. In any case, the English sentence is not clear. 

The quiz answer (shown below) and the lesson information don't match.  I wonder if you could help explain.  I don't see anywhere in the Lesson where it says, "Arriba, corriendo" means "Hurry, run!"  Is that information in another lesson?

I think I read in one of the lessons that decir was used to describe briefer statements, while contar was used when statements were more extensive or detailed.  Would it also be correct to say "Me contó que solo era cuestión de tiempo..."?

A esto libro le faltan dos paginas. I found this sentence and him confused why we use a with it
