There are 6 shapes on a 6x6 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 (2, 4)
Distance from target shape to red trapezoid at (3, 2): 3
Distance from target shape to blue square at (5, 2): 5
Distance from target shape to cyan rectangle at (3, 3): 2
Distance from target shape to pink right_triangle at (4, 4): 2
Distance from target shape to orange trapezoid at (1, 0): 5
Closest shape is the cyan rectangle at (3, 3) with distance 2</think>
