Question

1. el festival de rio es una fiesta ________.
2. vamos de vacaciones a un sitio ________.
3. mi hermano ________ se llama luis.

(options: carnaval, conocida; bonito, bosque; familia, mayor)

Explanation:

1. The Rio Festival (Carnaval) is a well-known celebration, so "conocida" fits grammatically and contextually to describe the fiesta.
2. "bonito" (nice/pretty) is an adjective that correctly describes a vacation spot, while "bosque" is a noun (forest) that does not fit the sentence structure here.
3. "mayor" is used to describe an older brother, which makes sense for identifying a sibling named Luis, while "familia" (family) does not fit the sentence.

Answer:

1. El Festival de Río es una fiesta conocida
2. Vamos de vacaciones a un sitio bonito
3. Mi hermano mayor se llama Luis
