There are 5 shapes on a 6x6 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, 4)
Distance from target shape to cyan right_triangle at (4, 3): 1
Distance from target shape to red square at (0, 4): 4
Distance from target shape to purple square at (0, 3): 5
Distance from target shape to brown right_triangle at (3, 0): 5
Closest shape is the cyan right_triangle at (4, 3) with distance 1</think>
