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