There are 6 shapes on a 6x6 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 (0, 5)
Distance from target shape to pink right_triangle at (4, 2): 7
Distance from target shape to yellow rectangle at (0, 2): 3
Distance from target shape to red right_triangle at (5, 0): 10
Distance from target shape to cyan trapezoid at (3, 3): 5
Distance from target shape to gray square at (2, 4): 3
Closest shape is the yellow rectangle at (0, 2) with distance 3</think>
