There are 5 shapes on a 4x4 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 (2, 3)
Distance from target shape to blue rectangle at (0, 2): 3
Distance from target shape to green right_triangle at (1, 2): 2
Distance from target shape to cyan square at (1, 3): 1
Distance from target shape to yellow square at (3, 0): 4
Closest shape is the cyan square at (1, 3) with distance 1</think>
