There are 6 shapes on a 4x4 grid. Which shape is closest to the red 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: red trapezoid at (0, 0)
Distance from target shape to brown trapezoid at (2, 1): 3
Distance from target shape to blue rectangle at (0, 2): 2
Distance from target shape to gray rectangle at (0, 3): 3
Distance from target shape to green square at (1, 1): 2
Distance from target shape to yellow trapezoid at (3, 0): 3
Closest shape is the blue rectangle at (0, 2) with distance 2</think>
