There are 5 shapes on a 9x9 grid. Which shape is closest to the brown rectangle 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 rectangle at (5, 0)
Distance from target shape to blue square at (7, 0): 2
Distance from target shape to cyan square at (5, 1): 1
Distance from target shape to pink trapezoid at (2, 7): 10
Distance from target shape to gray square at (2, 4): 7
Closest shape is the cyan square at (5, 1) with distance 1</think>
