Now time for our Geo Quiz we want you to name names. Usually for our Geo Quiz -- we ask you to name a place.

Today, we want to know what agency decides when the US should adopt a new name for a place.

Here are the initials of the agency -- BGN.

It deliberates over matters such as whether to use the name Burma or Myanmar...or whether the body of water between the Korean peninsula and the island of Japan is the East Sea or the Sea of Japan.

Sea of Japan

This agency got started in the 19th century. There was a lot of confusion then about the names of frontier cities and railway stations. Foreign names can still cause confusion. But the agency we want you to name tries to keep it all straight.

We'll give you a few minutes to name it and then, we'll let you know if you got it right.
