Question

why might beef cattle and hog producing states be located near corn belt states?
only hogs and cattle eat corn
the weather is nice for both corn, beef, and hogs
corn is a primary feed for cattle and hogs and is readily available
corn makes a good windbreak for cattle and hogs

Explanation:

Corn is a key feed for cattle and hogs. In corn - belt states, corn is abundant. This availability makes it cost - effective and convenient for livestock (beef cattle and hogs) farming. Other options are incorrect: not only hogs and cattle eat corn (many other animals can consume it too); while weather might be a factor, the primary reason related to the question's logic is feed availability; and corn as a windbreak is a less relevant factor compared to its role as feed.

Answer:

Corn is a primary feed for cattle and hogs and is readily available.
