Suppose y is a large negative number and x is a small positive number. In that case, x + y, 2x + y, and x + 2y would all yield a negative number. Because y is negative, 2y will be negative. In choice(E), 2x will be positive, y will be negative, and a positive minus a negative will always yield a positive.
