GRE Section 2 Quantitative Exam - Question 17

The relationship between the quantities in Column A and Column B cannot be determined from the information given. The expressions involve variables x, y, and z, with only x and y being partially constrained (x < 0 and y < 1). The value of z is required to make a definitive comparison between the two columns; its unknown value means that comparing the two expressions is indeterminate.
