I want to know the answer to the following question:
The northern and southern reaches of the desert are spare of what items?
All the background I'm provided with is that "In the central, hyperarid part, there are many subdivisions of the great desert such as the Tanezrouft, the Ténéré, the Libyan Desert, the Eastern Desert, the Nubian Desert and others.". Is that enough to answer the question?
Answer: no
