What is the currency of Brazil called?
Correct answer: Real

Nutshell
It's the only one that made sense, as it's the same name of currency in many other countries, not far from Portugal. Although not always spelled the same... Rial, Ryal, Real, Riyal... just like many countries have different types of Pesos and many others have their own dollars.
In fact, the Saudi Riyal is purposely tied to the US dollar, the exchange rate being something like 3.75:1 if I'm not mistaken (unless things have changed)
