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