There are 6 shapes on a 10x10 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 (6, 6)
Distance from target shape to gray rectangle at (0, 0): 12
Distance from target shape to yellow square at (2, 4): 6
Distance from target shape to brown rectangle at (3, 7): 4
Distance from target shape to orange rectangle at (4, 7): 3
Distance from target shape to green square at (5, 9): 4
Closest shape is the orange rectangle at (4, 7) with distance 3</think>
