When no order is specified, consider different -- especially non-alphabetic -- orderings of the given points.
The following case satisfies all of the constraints in the problem:
y=-10..............................0..................
z=9.....x=10
Here, z lies between x and y.
The following case satisfies all of the constraints in the problem:
y=-10..............................0..............................x=10....
z=11
Here, z does NOT lie between x and y.
Thus, the two statements combined are INSUFFICIENT.
The correct answer is
E.
