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