Learn More About Absolute Values Basics Here
STAT 1: w is an integer
itself is not sufficient as w can have any integer value
Ex: w = 100 will make the inequality true and w=0 can make the inequality false
So, NOT SUFFICIENT
STAT 2: w^2 < 1
=> -1<w<1
For all values of w in this range the inequality is true
Only for values of w >=1 the inequality will be false
SO, SUFFICIENT
So, answer will be B
Hope it helps!

Hi 1991sehwag,
This DS question can be solved with a bit of logic and TESTing VALUES.
We're asked if |W - 6| > 5. This is a YES/NO question.
Fact 1: W is an integer
IF....
W = 6
Then the answer to the question is NO.
IF....
W = 12
Then the answer to the question is YES.
Fact 1 is INSUFFICIENT
Fact 2: W^2 < 1
This Fact severely restricts the possible values of W. The range is -1 < W < 1. W can get "really close" to 1 or -1, but CANNOT be either of those values.
IF...
W = .99999
Then the answer to the question is YES.
IF...
W = 0
Then the answer to the question is YES.
IF....
W = - .99999
Then the answer to the question is YES.
Fact 2 is SUFFICIENT.
Final Answer:
GMAT assassins aren't born, they're made,
Rich
