问题 △RST lies in the XY-plane and points R and T have (x, y) coordinates (0,0) and (6,0) , respectively. The area of △RST is 12.

Column A                          Column B
The x-coordinate of R             The y-coordinate of S
选项 A、if the quantity in Column A is greater
B、if the quantity in Column B is greater
C、if the two quantity are equal
D、if the relationship cannot be determined from the information given
答案D
解析 △RST位于XY坐标平面中，顶点R和T的坐标(coordinate)分别是(0，0)和(6，0)。△RST的面积为12。
解：本题的正确答案是(D)。由△RST的面积为12，RT长度为6，可以推出S点的纵坐标为±4，而横坐标则为直线y=+4和y=-4上的任一点，所以本题为无法判断。
