How Well Do You Know The Flag For Each Olympic Nation?

Thousands of athletes from all over the world came to Rio this month to compete in a wide variety of sports at the 2016 Summer Olympics.

You probably didn't need to see the names of countries like the United States, Great Britain and France flash across your television screen during the opening ceremony in order to recognize the flags of those nations.

However, did you really know the nation of Bhutan was in the building just by looking at their flag?

I think not.

And when the country of Mauritania entered the Maracanã on Friday, August 5, well, I definitely needed to read the NBC chyron to know what was going on.

It's been over a week since the opening ceremony of the 2016 Summer Olympics took place, and I know you've been watching every minute of NBC's endless coverage.

So, you know the difference between the flag of Luxembourg and the flag of Lithuania by this point, right? How about Mali versus Malta?

If you think you could pick out the flags of those four nations with ease, then you'll have no problem acing the following quiz.

Think you can identify the flags of each Olympic nation? I'd wager otherwise.
