I want to know the answer to the following question:
How many prefecture-size cities are in the province of Anhui?
All the background I'm provided with is that "On its western boundary is Anhui province, where Nanjing borders five prefecture-level cities, Chuzhou to the northwest, Wuhu, Chaohu and Maanshan to the west and Xuancheng to the southwest.". Is that enough to answer the question?
Answer: yes
