There are 5 shapes on a 4x4 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 (0, 1)
Distance from target shape to red square at (3, 1): 3
Distance from target shape to green right_triangle at (1, 3): 3
Distance from target shape to yellow rectangle at (3, 3): 5
Distance from target shape to orange rectangle at (1, 0): 2
Closest shape is the orange rectangle at (1, 0) with distance 2</think>
