than or less than but not equal to...
So right away we can see that A and C are going to be raccoon food.
Let's brute force the rest... we'll take a look at E and work our way up.
Here, x is GREATER than negative 4... but already we're in foul territory because the
line here doesn't connect or tie in with negative 4 at all...
...it just crosses over it... so we can quickly toss E. On to D.
Here x is bigger than negative 2... which also doesn't work.
The line shown is LOWER or more negative than negative 2, not bigger. So we can toss D.
Last chance is B... which ... works!
X is smaller or more negative than negative 2 and not equal to it here - check;
...and x is greater than but not equal to positive 4 here - check.
B is our answer. Done.
