I want to know the answer to the following question:
How many of the New Delhi Metro's stations are located at ground level?
All the background I'm provided with is that "The network consists of six lines with a total length of 189.63 kilometres (117.83 miles) with 142 stations, of which 35 are underground, five are at-grade, and the remainder are elevated.". Is that enough to answer the question?
Answer: yes
