I want to know the answer to the following question:
Which country lies on Congo's northwest border?
All the background I'm provided with is that "It is bordered by five countries: Gabon to the west; Cameroon to the northwest; the Central African Republic to the northeast; the Democratic Republic of the Congo to the east and south; and the Angolan exclave of Cabinda to the southwest.". Is that enough to answer the question?
Answer: yes
