There are 6 shapes on a 6x6 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 (4, 5)
Distance from target shape to green right_triangle at (3, 0): 6
Distance from target shape to gray trapezoid at (3, 1): 5
Distance from target shape to yellow trapezoid at (4, 0): 5
Distance from target shape to cyan right_triangle at (3, 4): 2
Distance from target shape to brown rectangle at (0, 0): 9
Closest shape is the cyan right_triangle at (3, 4) with distance 2</think>
