There are 4 shapes on a 5x5 grid. Which shape is closest to the blue 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: blue trapezoid at (1, 2)
Distance from target shape to red rectangle at (2, 0): 3
Distance from target shape to gray rectangle at (1, 1): 1
Distance from target shape to brown rectangle at (1, 0): 2
Closest shape is the gray rectangle at (1, 1) with distance 1</think>
