There are 5 shapes on a 5x5 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, 3)
Distance from target shape to cyan square at (1, 4): 3
Distance from target shape to pink rectangle at (4, 0): 4
Distance from target shape to green trapezoid at (2, 0): 4
Distance from target shape to blue trapezoid at (2, 1): 3
Closest shape is the cyan square at (1, 4) with distance 3</think>
