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, 1)
Distance from target shape to pink right_triangle at (0, 4): 4
Distance from target shape to cyan right_triangle at (0, 3): 3
Distance from target shape to orange square at (3, 2): 3
Closest shape is the cyan right_triangle at (0, 3) with distance 3</think>
