There are 5 shapes on a 7x7 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 (0, 1)
Distance from target shape to brown rectangle at (4, 5): 8
Distance from target shape to orange trapezoid at (1, 6): 6
Distance from target shape to red right_triangle at (5, 5): 9
Distance from target shape to blue square at (4, 1): 4
Closest shape is the blue square at (4, 1) with distance 4</think>
