To determine: If 'w' is between -1 and 2 on the number line
(1) w is to the right of -2 on the number line.
-2__-1__0__1__2__
'w' is to the right of -2 => It could be between -1 and 2, or it could be between -2 and -1, or even after 2. No definite answer
NOT SUFFICIENT
(2) w is to the left of 1 on the number line.
-1__0__1__2__
'w' is to the left of 1 => It could be between -1 and 2, or it could be to the left of -1 or even to the right of 2. No definite answer
NOT SUFFICIENT
(1) + (2) combined:
'w' is to the right of -2 and to the left of 1
-2__-1__0__1__2__
=> w could be between -1 and 2, or it could be between -2 and -1. No definite answer
NOT SUFFICIENT
Answer - E
