Answer- Cómo está
Cómo está means how are you
I'm pretty sure the correct answer is D, not B.
"Conoces tu el Valle de Silicio" makes more sense than "Sabes tu el Valle de Silicio". By saying "Conoces tu el Valle de Silicio" you are properly asking in Spanish "Do you know of the Silicone Valley?" or "Do you know about the Silicone Valley?"
So I would go with D, and Spanish is my native language.
The correct answer is “creyera”
What are we meant to write in the space? Anything related to the word talk?
If that’s the case..
“Puedes hablar” means “Can you talk?”
“Cuando hablar” means “When speaking”
Let me know if any of this helps!
