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