a. x + 1 and y – 1 are consecutive negative integers.
b. x is an even integer.


\(x\) and \(y\) are consecutive integers means that either:
\(y=x+1\) (for example \(x=-5\) and \(y=-4\)), in this case \(x<y\);
OR:
\(x=y+1\) (for example \(x=-5\) and \(y=-6\)), in this case \(x>y\).

So the we should determine which case we have.

(1) \(x+1\) and \(y-1\) are consecutive negative integers --> again either \(x+1=(y-1)+1\) --> \(x+1=y\) (first case so \(x<y\)) or \(y-1=(x+1)+1\) --> \(y=x+3\), which is not possible as \(x\) and \(y\) are consecutive integers (difference between two consecutive integers can not equal to 3). So only first case is possible: \(x<y\). Sufficient.

(2) \(x\) is an even integer. Clearly insufficient.

Answer: A.

Alternative approach: we can also translate the question into absolute equality.

given : |x-y| = 1

statement 1: |x+1-y+1| = 1
so |x+1-y+1| = |x-y|
if both sides have same sign, then x-y+2 = x-y; and 2 = 0 ---> invalid
if both sides have opposite signs, then x-y+2 = y-x ; and 2x + 2 = 2y ; and x+1 = y ---> so y is always greater than x by 1 ---> sufficient

statement 2: x is even ---> so y is odd but can still be smaller than or bigger than x by 1 ---> insufficient

Is x > y or x < y ????
+If x > y, we can have x +1 & y, or x & y - 1
+If x < y, we can have x - 1 & y, or x & y+1

ST1: x + 1 and y – 1 are consecutive negative integers.
--->x > y (basing on the above analysis)

ST2: We couldn't determine how x & y should be---->NS
