¿cuándo vas a la playa? generalmente estoy aquí. generalmente voy los domingos. generalmente estoy enfermo. generalmente van los martes.

¿Cuándo vas a la playa? means "When are you going to the beach?"

Let's elimante the answers that aren't a possibility:

1. Generalmente estoy aquí.

2. Generalmente voy los domingos.

3. Generalmente estoy enfermo.

4. Generalmente van los martes.

We know that this question was asked to you, so the answer can't be something that refers to they. #4 uses "van" instead of "voy", so it can not be #4.

We know that the answer can't be #3. Think about it in english - "When are you going to the beach?" answered with "I'm usually sick." So that doesn't work.

We're left with #1 and #2. Because the question asks "when", we want to answer with a date or time, not just "I'm usually here" (like #1).

The answer is "Generalmente voy los domingos."

answer:   i cant   remeber exactly but i just got out of spanish a few months ago and the dbas are really easy. just relax, and have your notes in front of you. they are going to ask you the basics study the notes you wrote and you will be fine, make sure to really study grammar and pronuciation. the spanish teachers are usually nice so if you mess up they will go easy on you. you got this, you did the lessons and tests just focus and dont overthink the process.
