This is the complete conversation between Daniel and Sara in Spanish:
Daniel: ¿Jamás estás enferma?
Sara: No, no estoy enferma casi nunca.
Daniel: ¡Qué suerte!
Sara: Si. Es importante tener buena salud.
In this exercise, you have to complete the conversation using the words related to vocabulary about negation.
"Jamás" and "nunca" are synonyms of the word never.
No is the same as in English, a way of negation.
