Final answer:
The Great Plains region, including states like Texas, Nebraska, Kansas, California, and Oklahoma, has a lot of grasslands that support large cattle ranches and farms.
Step-by-step explanation:
The area or state that has a lot of grasslands that support large cattle ranches and farms is the Great Plains region. This includes states like Texas, Nebraska, Kansas, California, and Oklahoma.
Ranching is a common agricultural alternative in these areas because cattle require mostly grass and space. The dry flatlands of the Great Plains, where irrigated farming is unavailable, provide ideal conditions for cattle ranching.
These regions lead the country in cattle production and have vast grasslands that are suitable for supporting large-scale farming operations.
