There are 3 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 (4, 3)
Distance from target shape to yellow trapezoid at (6, 2): 3
Distance from target shape to brown trapezoid at (4, 4): 1
Closest shape is the brown trapezoid at (4, 4) with distance 1</think>
