Hola!

I'm doing my spanish homework and I'm having some difficulty understanding a couple of the concepts. I'm doing some of the practice work and whenever I enter in my answers they aren't correct, but it doesn't explain WHY. If someone could help me understand WHY the correct answers are correct that would really help my studying. thank you!!
