Today's Geo Quiz takes us to Southern Africa. To identify this African country, we're going to give you the names of a couple of rivers.

The first one is the Zambezi River. It forms this country's southern border with Zimbabwe. Your second clue is the Luangwa River.

It's a major tributary of the Zambezi.

It also floods regularly, making this part of the country an ideal habitat for hippos.

We promise to name this country before too long... or I'm a HIPPO-crite.

OK, at least the hippo's laughing.
