¿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!~
You use saber to describe a fact, information, or how to do something.
And you use conocer to say that you are familiar with something either a person, place, or thing.
Basically saber means to know of something, and conocer means to be familiar with someting.
