Spanish language Q&A Forum

I'm a bit confused by this example. Why is it "al que"? Could it be "al cual"? Thanks for your help!

MOTHER: Of course, the guy who you met at the Spanish course at University,

Why is it "*por* dónde estaremos" instead of "dónde estaremos" in the sample question? 

In the test question: ¿Quién es ________ de tus amigos? (Who is the most generous of your friends?)

I incorrectly assumed that because "de tus amigos" doesn't specify the gender of "Quien es" in Spanish, that "lo" would be appropriate rather than "el" (correct answer). Because only the response can reveal the gender e.g. - "Carla es la más generosa de mis amigos" o "Jorge es el más generoso de mis amigos". In other words, why is "el" correct in this case even if the "quién es" might turn out to be female? (I did notice that the hint was "generous = generoso" but (falsely?) assumed it was being generic rather than specifying un amigo masculino).

Can you please clarify?

Thank you

actually to pocas (if plural- pacientes)

Not a huge deal, but I learned monte = hill and montaña = mountain and not the other way around. Maybe I'm wrong.

What would you suggest as the "best" way to approach the lessons in kwizIQ.  The initial test recommended B2.  Is it best to study only the lessons suggested in the dashboard  and trust the system to move me up and also to eventully  fill in gaps from lower levels, or to also take tests for the lower levels and review those lessons, sort of jumping around from level to level, topic to topic.

Thanks!
