To answer your question accurately, I would need to have access to the specific map you are referring to. However, based on the typical historical context regarding agriculture in the U.S. around 1860:
- The statement regarding the territories and several states in the Midwest producing no crops is likely inaccurate, as the Midwest was known for its agricultural production.
- The southern-most states indeed relied heavily on cash crops, particularly cotton, but not exclusively on one crop.
- The statement about Louisiana holding a monopoly on the sugar industry may be somewhat correct, as Louisiana was a leading producer of sugar, but "monopoly" might be too strong of a term.
- The statement that most states in the South had at least two crops on which their economy relied is often accurate, as many Southern states produced not only cotton but also other crops like tobacco, rice, and sugarcane.
Without the specific map data, if I had to choose the best general description, I would lean towards stating that "Most states in the South had at least two crops on which their economy relied," as this reflects the agricultural diversity present in the South during that time.
