There are 6 shapes on a 5x5 grid. Which shape is closest to the blue 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: blue rectangle at (4, 0)
Distance from target shape to gray trapezoid at (0, 4): 8
Distance from target shape to red rectangle at (2, 3): 5
Distance from target shape to orange trapezoid at (4, 1): 1
Distance from target shape to cyan trapezoid at (3, 2): 3
Distance from target shape to yellow right_triangle at (1, 4): 7
Closest shape is the orange trapezoid at (4, 1) with distance 1</think>
