Answer: B. Minnesota has a far greater chance at snowfall than Missouri each year
First, it will be helpful to know where the Southwest, Minnesota, Missouri, and Northeast are.
-> I have attached a picture showing these.
[✗] A. the southwest is prone to freezing temperatures during the year.
-> The southwest is part of the warmest climate, so this option does not make sense.
[✓] B. Minnesota has a far greater chance at snowfall than Missouri each year
-> Minnesota has dark blue while Missouri is yellow, using the key we can tell that this means Missouri is usually warmer than Minnesota, giving Minnesota a greater chance at snowfall.
[✗] C. the Northeast is warmer than the southeast each year.
-> When looking at the Northeast, we see a chunk of dark blue, but in the Southeast, we see mostly oranges. This tells us that this option is false.
