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