There are 6 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, 0)
Distance from target shape to orange trapezoid at (1, 0): 1
Distance from target shape to gray right_triangle at (0, 2): 2
Distance from target shape to blue trapezoid at (3, 1): 4
Distance from target shape to pink trapezoid at (2, 0): 2
Distance from target shape to brown right_triangle at (2, 3): 5
Closest shape is the orange trapezoid at (1, 0) with distance 1</think>
