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