There are 4 shapes on a 8x8 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, 4)
Distance from target shape to yellow square at (5, 2): 7
Distance from target shape to brown square at (5, 7): 8
Distance from target shape to cyan trapezoid at (5, 0): 9
Closest shape is the yellow square at (5, 2) with distance 7</think>
