There are 5 shapes on a 7x7 grid. Which shape is closest to the pink rectangle 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 rectangle at (6, 5)
Distance from target shape to yellow trapezoid at (2, 1): 8
Distance from target shape to orange trapezoid at (5, 5): 1
Distance from target shape to blue rectangle at (1, 2): 8
Distance from target shape to brown square at (4, 4): 3
Closest shape is the orange trapezoid at (5, 5) with distance 1</think>
