There are 6 shapes on a 7x7 grid. Which shape is closest to the yellow 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: yellow trapezoid at (3, 3)
Distance from target shape to cyan right_triangle at (5, 0): 5
Distance from target shape to orange rectangle at (4, 6): 4
Distance from target shape to brown trapezoid at (3, 4): 1
Distance from target shape to green rectangle at (2, 6): 4
Distance from target shape to blue rectangle at (3, 2): 1
Closest shape is the brown trapezoid at (3, 4) with distance 1</think>
