I want to know the answer to the following question:
Which river separates the main Aravelli ranges?
All the background I'm provided with is that "Mount Abu lies at the southwestern end of the range, separated from the main ranges by the West Banas River, although a series of broken ridges continues into Haryana in the direction of Delhi where it can be seen as outcrops in the form of the Raisina Hill and the ridges farther north.". Is that enough to answer the question?
Answer: yes
