At end of last week, I visited (went to visit) my aunt Lilia in the country.
le ( consegui) I got her some books from the library of the university because she asked me for it . (me los pidio , asked me for them.....)
verbs are ok at the preterito perfecto simple as "fui"
hope that's what you were asking for
Copán tiene inscripciones que cuentan la historia de sus reyes.
cierto
¿Tú subiste por la escalera o en el ascensor?
Why subiste?
Subeste, nope, nope, no, this isn't a word in Spanish. This is how we know this one is wrong.
Subaste? Not a word either. This is crossed out.
Subes, This is a word but it's stating something instead of asking a question. "Tú subes por las escaleras = You climb/ go up the stairs".
So subiste is the right one!
Hope this helps!~
