| Okay, I'm assuming you use the CIA World Factbook as your source, but it's wrong on one major account. Botswana should not be accepted for 3; it is four. It shares a border with Zimbabwe, South Africa, Namibia, and Zambia. The border with Zambia is about a kilometer long (and is entirely along the Zambezi River), but the countries do border each other and river borders are generally considered land borders. |
