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 (2, 5)
Distance from target shape to pink trapezoid at (4, 1): 6
Distance from target shape to green square at (5, 4): 4
Distance from target shape to blue rectangle at (1, 5): 1
Closest shape is the blue rectangle at (1, 5) with distance 1</think>
