There are 3 shapes on a 7x7 grid. Which shape is closest to the brown 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: brown trapezoid at (2, 4)
Distance from target shape to gray trapezoid at (4, 5): 3
Distance from target shape to orange right_triangle at (5, 5): 4
Closest shape is the gray trapezoid at (4, 5) with distance 3</think>
