I think The upper midwest is the best choice.
In the 1800s, westward expansion brought settlers and their livestock into direct contact with native predator and prey species. Much of the wolves’ prey base was destroyed as agriculture flourished. With the prey base removed, wolves began to prey on domestic stock, which resulted in humans eliminating wolves from most of their historical range. Predator control, including poisoning, was practiced here in the late 1800s and early 1900s. Other predators such as bears, cougars, and coyotes were also killed to protect livestock and “more desirable” wildlife species, such as deer and elk.

For example Puerto Rico is its own country but is territory of the United States.
The correct answer is - False.
The mechanization in the agriculture contributed to less people being involved in it, and that is because with the mechanization much less human labor is needed since the mechanization is doing the work for multiple people and animals, with the same or better efficiency, and also quicker and cheaper.
