There are 4 shapes on a 6x6 grid. Which shape is closest to the pink 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: pink trapezoid at (0, 5)
Distance from target shape to yellow trapezoid at (2, 0): 7
Distance from target shape to green right_triangle at (1, 0): 6
Distance from target shape to cyan square at (0, 4): 1
Closest shape is the cyan square at (0, 4) with distance 1</think>
