There are 5 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 (3, 1)
Distance from target shape to green rectangle at (2, 3): 3
Distance from target shape to brown right_triangle at (1, 2): 3
Distance from target shape to gray square at (0, 0): 4
Distance from target shape to cyan square at (2, 2): 2
Closest shape is the cyan square at (2, 2) with distance 2</think>
