There are 6 shapes on a 3x3 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 (0, 1)
Distance from target shape to blue square at (0, 0): 1
Distance from target shape to yellow right_triangle at (1, 1): 1
Distance from target shape to brown rectangle at (2, 1): 2
Distance from target shape to gray right_triangle at (2, 2): 3
Distance from target shape to green trapezoid at (1, 0): 2
Closest shape is the blue square at (0, 0) with distance 1</think>
