There are 6 shapes on a 5x5 grid. Which shape is closest to the cyan 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: cyan rectangle at (4, 2)
Distance from target shape to yellow square at (4, 0): 2
Distance from target shape to purple right_triangle at (2, 4): 4
Distance from target shape to brown rectangle at (1, 3): 4
Distance from target shape to gray trapezoid at (2, 2): 2
Distance from target shape to pink trapezoid at (1, 0): 5
Closest shape is the yellow square at (4, 0) with distance 2</think>
