There are 5 shapes on a 9x9 grid. Which shape is closest to the pink 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: pink trapezoid at (0, 0)
Distance from target shape to blue rectangle at (8, 3): 11
Distance from target shape to cyan rectangle at (5, 2): 7
Distance from target shape to orange trapezoid at (3, 1): 4
Distance from target shape to brown trapezoid at (3, 7): 10
Closest shape is the orange trapezoid at (3, 1) with distance 4</think>
