There are 5 shapes on a 7x7 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 (4, 2)
Distance from target shape to brown trapezoid at (6, 6): 6
Distance from target shape to gray square at (5, 2): 1
Distance from target shape to red trapezoid at (3, 3): 2
Distance from target shape to orange trapezoid at (6, 1): 3
Closest shape is the gray square at (5, 2) with distance 1</think>
