I always viewed the < > signs as alligator mouths that eat the bigger number. With this in mind, we know that x is bigger than 2, so we have the 'mouth' facing x (2<x). It also says that x is less than 8, so the 'mouth' has to be facing the 8 (x<8). So we put these two together to get (2<x<8). B is your answer!
