Answer:
Explanation: The statement that best describes the reason for the change between the two maps is:
The United States acquired the land after a war with Spain.
This statement suggests that the change depicted in the maps is due to the United States gaining ownership of the land as a result of a war with Spain. Wars can often lead to territorial changes and shifts in national boundaries. In this case, the acquisition of land after a war with Spain would explain the change shown in the maps.
The other options provided in the question, such as the United States signing a treaty with the British for use of the land, factory owners needing a faster way to access natural resources, or agricultural expansion relying on having a way to, do not directly explain the change between the two maps.
It's important to note that without specific information or context about the maps being referred to, it is difficult to provide a more detailed answer. However, based on the options provided, the statement about the United States acquiring the land after a war with Spain is the most appropriate explanation for the change depicted in the maps.
