I want to know the answer to the following question:
What is the main retail area of the South Bronx?
All the background I'm provided with is that "The Hub–Third Avenue Business Improvement District (B.I.D.), in The Hub, is the retail heart of the South Bronx, located where four roads converge: East 149th Street, Willis, Melrose and Third Avenues.". Is that enough to answer the question?
