Step 1 : Introduction to the question "5. The Gambia is split east to west by which of the following rivers? (Don't think too hard on this one.)"
...1. The Gambia River 2. The Indus River 3. The Nile River 4. The Po River The Gambia River is one of the larger rivers found in West Africa and is approximately 700 miles (1,130 km) long. It runs from the country of Guinea westward to the Atlantic Ocean. Only about half of the river is navigable and runs right through the center of the country. The country of The Gambia is very small and consists of little more than the river and the banks on either side. The Gambia is only about 4,000 sq mi and water covers over 10% of the country.
