There are 5 shapes on a 8x8 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 (5, 7): 6
Distance from target shape to green trapezoid at (0, 7): 9
Distance from target shape to brown rectangle at (7, 5): 6
Distance from target shape to pink square at (7, 6): 7
Closest shape is the yellow trapezoid at (5, 7) with distance 6</think>
