There are 6 shapes on a 7x7 grid. Which shape is closest to the brown trapezoid 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 trapezoid at (4, 5)
Distance from target shape to red rectangle at (5, 4): 2
Distance from target shape to green rectangle at (0, 5): 4
Distance from target shape to yellow right_triangle at (6, 2): 5
Distance from target shape to cyan rectangle at (4, 6): 1
Distance from target shape to orange right_triangle at (0, 1): 8
Closest shape is the cyan rectangle at (4, 6) with distance 1</think>
