There are 4 shapes on a 7x7 grid. Which shape is closest to the cyan square 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 square at (1, 0)
Distance from target shape to brown right_triangle at (2, 1): 2
Distance from target shape to green trapezoid at (5, 0): 4
Distance from target shape to red rectangle at (1, 4): 4
Closest shape is the brown right_triangle at (2, 1) with distance 2</think>
