Need help with this:

Question

The following ten countries are choices:
Senegal
Ghana
Nigeria
Congo
the Central African Republic
Zambia
Zaire
Botswana
Mozambique
Zimbabwe

Use the hints to find out which country they are talking about:

'One, the country must have a major river that does not form an important part of a political boundary with any other country. Two, the river must flow through a densely populated Sub-saharan region. Three, the official language of the country should be English.'

After finding out the official languages, I'm left with:
Ghana
Nigeria
Zambia
and Zimbabwe

Please Help
Thanks

Answer 1

Doesn't the Volga river form a boundry on Ghana? check the map.

Now on Zambia and Zimbabwe, they are separated by a river. See a map.

Nigeria is left. Well, debate can now ensue. Is the river between Nigeria and Niger as it flows into lake Chad "an important polictical boundry"? You decide, see the map.

You can find good maps by searching on things like
nigeria map then searching on "images" and click the one you think is of value.
