Thank you!

You're welcome.

Well, Brazil is indeed a unique South American country, and the answer is C. Its official language is Portuguese. You see, while the rest of South America predominantly speaks Spanish, Brazil decided to go against the trend and opted for Portuguese. Maybe they just wanted to spice things up a bit, who knows? So, if you're in Brazil and find yourself trying to order tacos or say "hola," chances are you won't get very far. But don't worry, just break out a friendly "Oi" and you'll be good to go!

The correct answer is C. Its official language is Portuguese.

To determine how Brazil is different from all other South American countries, we can analyze the given options:
A. "Most of its people live in cities" is not a distinguishing characteristic, as many South American countries have a significant urban population.
B. "Its culture is a blend of several cultures" is a common trait among many South American countries, where diverse cultural influences can be found.
C. "Its official language is Portuguese" is the correct answer. Unlike other South American countries, Brazil is the only one where Portuguese is the official language. The other countries predominantly speak Spanish.
D. "Most of its people are Christian" is not exclusive to Brazil, as the majority of South American countries have a predominantly Christian population.

By considering these options, we can conclude that Brazil's official language being Portuguese sets it apart from all other South American countries.
