Question

Tengo una profesora nueva, la Sra. López. ¿La _______ tú?

conoce
conoces
sabes
sabe

Answer 1

Conoces because it’s like saying Do you know her. Conoces translates to you know and that’s what you would use:)

Answer 2

The answer is conoces.

Step-by-step explanation:

It's "conoces" because since the sentence is a question and not a statement the only word that would grammatically work with the sentence is that word.
