There are 6 shapes on a 6x6 grid. Which shape is closest to the red 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: red trapezoid at (4, 5)
Distance from target shape to yellow square at (0, 3): 6
Distance from target shape to pink trapezoid at (5, 5): 1
Distance from target shape to cyan rectangle at (0, 1): 8
Distance from target shape to gray square at (3, 5): 1
Distance from target shape to green rectangle at (5, 3): 3
Closest shape is the pink trapezoid at (5, 5) with distance 1</think>
