There are 5 shapes on a 5x5 grid. Which shape is closest to the brown rectangle in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: brown rectangle at (4, 0)
Distance from target shape to gray trapezoid at (2, 0): 2
Distance from target shape to blue square at (1, 3): 6
Distance from target shape to green square at (4, 3): 3
Distance from target shape to purple square at (0, 1): 5
Closest shape is the gray trapezoid at (2, 0) with distance 2</think>
