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