There are 5 shapes on a 8x8 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 (1, 1)
Distance from target shape to pink trapezoid at (5, 0): 5
Distance from target shape to gray right_triangle at (2, 0): 2
Distance from target shape to cyan right_triangle at (4, 7): 9
Distance from target shape to red rectangle at (3, 2): 3
Closest shape is the gray right_triangle at (2, 0) with distance 2</think>
