There are 6 shapes on a 9x9 grid. Which shape is closest to the orange square in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: orange square at (4, 3)
Distance from target shape to gray trapezoid at (0, 2): 5
Distance from target shape to purple trapezoid at (1, 1): 5
Distance from target shape to red square at (0, 0): 7
Distance from target shape to brown trapezoid at (0, 1): 6
Distance from target shape to yellow square at (5, 1): 3
Closest shape is the yellow square at (5, 1) with distance 3</think>
