There are 6 shapes on a 8x8 grid. Which shape is closest to the pink 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: pink rectangle at (3, 4)
Distance from target shape to cyan trapezoid at (0, 5): 4
Distance from target shape to red trapezoid at (5, 2): 4
Distance from target shape to yellow right_triangle at (3, 0): 4
Distance from target shape to brown rectangle at (6, 6): 5
Distance from target shape to orange right_triangle at (7, 5): 5
Closest shape is the cyan trapezoid at (0, 5) with distance 4</think>
