I want to know the answer to the following question:
What lakes are in the middle of Nanjing?
All the background I'm provided with is that "Natural lakes such as Xuanwu Lake and Mochou Lake are located in the centre of the city and are easily accessible to the public, while hills like Purple Mountain are covered with evergreens and oaks and host various historical and cultural sites.". Is that enough to answer the question?
Answer: yes
