Is -3<x<4?

1) -2<x<3

2) -4<x<4

We need to determine whether -3 < x < 4.

Statement One Alone:-2 < x < 3

Since x is greater than -2 and less than 3, it must be between -3 and 4. Statement one alone is sufficient to answer the question.

Statement Two Alone:-4 < x < 4

Statement two alone is not sufficient to answer the question. For instance, if x = -3.5, it’s not between -3 and 4; however if x = 0, it is between -3 and 4.

Answer: A
