There are 4 shapes on a 6x6 grid. Which shape is closest to the orange trapezoid in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: orange trapezoid at (0, 0)
Distance from target shape to yellow right_triangle at (3, 1): 4
Distance from target shape to cyan right_triangle at (5, 4): 9
Distance from target shape to gray trapezoid at (0, 2): 2
Closest shape is the gray trapezoid at (0, 2) with distance 2</think>
