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 (4, 2)
Distance from target shape to gray rectangle at (1, 2): 3
Distance from target shape to brown square at (3, 0): 3
Distance from target shape to cyan square at (4, 1): 1
Distance from target shape to orange rectangle at (3, 4): 3
Closest shape is the cyan square at (4, 1) with distance 1</think>
