Answer: Castaño, Bonita
Explanation: We must complete the conversation:
—mi padre, juan, tiene una hermana en cuba. Ella es sandra. Ellos tienen el pelo ________.
—¿cómo es sandra?
—es ________.
Where a rough translation of this is:
-My father, Juan, has a sister in Cuba. She is called Sandra. They both have the hair _____.
- How is Sandra?
- She is ______.
The option that makes sense here is the last one; castaño; bonita, because castaño is a hair colour, and bonita means pretty, so the full conversation is:
—mi padre, juan, tiene una hermana en cuba. Ella es sandra. Ellos tienen el pelo castaño.
—¿cómo es sandra?
—es bonita.
