There are 5 shapes on a 10x10 grid. Which shape is closest to the brown 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: brown square at (8, 5)
Distance from target shape to yellow trapezoid at (0, 2): 11
Distance from target shape to orange rectangle at (6, 1): 6
Distance from target shape to blue square at (3, 2): 8
Distance from target shape to cyan rectangle at (1, 8): 10
Closest shape is the orange rectangle at (6, 1) with distance 6</think>
