For our Geo Quiz today --- we're zooming in on the plight of mountain gorillas in Africa.

Mountain gorilla

The ongoing conflict in the Democratic Republic of the Congo has ravaged the forest habitat of mountain gorillas. In many cases, even park rangers have been forced to flee protected areas.

The fighting is not the only threat to these endangered great apes. Poaching and loss of habitat remain huge problems.

But before we check-in with an expert conservationist for an update we want you to name the 3 "range states", the 3 African countries where the mountain gorilla population struggles to hang on.

Locally this region is called the Virunga Volcano Region. The dense mountain rainforests here extend across the international borders of 3 African countries.

Can you name them?
