There are 4 shapes on a 6x6 grid. Which shape is closest to the orange trapezoid in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: orange trapezoid at (4, 4)
Distance from target shape to blue square at (1, 3): 4
Distance from target shape to cyan rectangle at (5, 5): 2
Distance from target shape to gray right_triangle at (2, 4): 2
Closest shape is the cyan rectangle at (5, 5) with distance 2</think>

<answer>(5, 5)</answer>
