There are 5 shapes on a 9x9 grid. Which shape is closest to the brown rectangle 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 rectangle at (3, 2)
Distance from target shape to blue square at (5, 0): 4
Distance from target shape to yellow trapezoid at (5, 3): 3
Distance from target shape to cyan rectangle at (4, 8): 7
Distance from target shape to gray square at (2, 3): 2
Closest shape is the gray square at (2, 3) with distance 2</think>
