There are 4 shapes on a 4x4 grid. Which shape is closest to the pink 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: pink trapezoid at (1, 1)
Distance from target shape to yellow square at (0, 1): 1
Distance from target shape to cyan trapezoid at (3, 0): 3
Distance from target shape to brown right_triangle at (0, 0): 2
Closest shape is the yellow square at (0, 1) with distance 1</think>
