There are 6 shapes on a 7x7 grid. Which shape is closest to the orange 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: orange trapezoid at (4, 2)
Distance from target shape to yellow trapezoid at (0, 3): 5
Distance from target shape to pink right_triangle at (5, 2): 1
Distance from target shape to purple trapezoid at (3, 2): 1
Distance from target shape to brown square at (0, 4): 6
Distance from target shape to red rectangle at (1, 0): 5
Closest shape is the pink right_triangle at (5, 2) with distance 1</think>
