The question "¿Vas a bailar en la fiesta?" translates to "Are you going to dance at the party?" in English.
The responses are:
- "No, no vas a bailar." - "No, you are not going to dance."
- "Sí, voy a bailar." - "Yes, I am going to dance."
- "Sí, va a bailar." - "Yes, he/she is going to dance."
- "No ir a bailar." - "Not going to dance." (This response is grammatically incorrect in Spanish; it should be "No voy a bailar" to mean "I am not going to dance.")
