I want to know the answer to the following question:
The Forth Thieves and Roach Guards were two gangs that operated in what area of New York in the 1820s?
All the background I'm provided with is that "The 20th century saw a rise in the Mafia, dominated by the Five Families, as well as in gangs, including the Black Spades.". Is that enough to answer the question?
Answer: no
