There are 3 shapes on a 4x4 grid. Which shape is closest to the yellow 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: yellow trapezoid at (0, 3)
Distance from target shape to cyan right_triangle at (3, 3): 3
Distance from target shape to pink square at (0, 0): 3
Closest shape is the cyan right_triangle at (3, 3) with distance 3</think>

<answer>(3, 3)</answer>
