4 y 6 grados de alcohol shows as "degrees" of alcohol. Are "degrees" and "percent" interchangeable in Spanish? I've never seen it that way in English

Hola…..¿por qué se usa el imperfecto de subjuntivo con una oración que empiece con “No sabía que_________”.  No entiendo el “trigger” en este caso.

"con todas las velas?" Right now it says "todas la velas"

For this question about recibir in the imperfect, I inserted the "personal a"  but it was marked wrong. Ayudame por favor!

In his small apartment he didn't receive guests. --> En su apartamento pequeño no recibía a visitas. (recibía was correct but adding a was marked wrong)

I think 55% and 37% should be written in letters for the sake of pronouncing "porcentaje"

There's a quiz question that I got wrong because there is no indication whether the speaker sees the event as probable or not.  A note on this would help so we don't have to guess.

Tengo una pregunta.
