I want to know the answer to the following question:
What is the largest Nigerian city?
All the background I'm provided with is that "This huge waste management problem is also attributable to unsustainable environmental management lifestyles of Kubwa Community in the Federal Capital Territory, where there are habits of indiscriminate disposal of waste, dumping of waste along or into the canals, sewerage systems that are channels for water flows, etc.". Is that enough to answer the question?
Answer: no
