DS from OG.

OA is D for the following reasons:

When you first see a DS question, see if there is anyway to simplify the question stem

In this case, since |x| is positive, we can divide both sides by |x| giving us a new question stem -->

is x < 2?S1: x<0, therefore x must be <2 =

sufficientS2: x = -10 and -10 < 2 =

sufficientLet me know if this helps!

The OA is wrong here because of the following reasons:

(1) if x=-10 then -100<-20, on the other hand if x= -1, x<0 then the inequality changes from < to >, namely, -1 > -2 ; This statement is absolutely insufficient!

(2) This statement is obviously sufficient!

So, the correct answer is not

~~D~~, but
