There are 6 shapes on a 7x7 grid. Which shape is closest to the pink 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: pink trapezoid at (0, 1)
Distance from target shape to orange trapezoid at (2, 6): 7
Distance from target shape to gray rectangle at (2, 0): 3
Distance from target shape to cyan square at (6, 5): 10
Distance from target shape to brown right_triangle at (4, 2): 5
Distance from target shape to yellow rectangle at (2, 4): 5
Closest shape is the gray rectangle at (2, 0) with distance 3</think>
