With Quantitative Comparisons, always think logically before fully calculating.
Note that the terms of Set A include 0. Anything x 0 will equal 0. Therefore, the product of each element in A = 0
Now, note in Set B, that there is an arithmetic sequence where the median = 0. Each of the positive values cancel with their equivalent negative value. -4 + 4 = 0. -2 + 2 = 0. Therefore the sum of the values in Set B also = 0
0 + 0 = 0. Thus, the quantities are equal. Select Choice C.
