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, 3)
Distance from target shape to yellow square at (1, 4): 2
Distance from target shape to purple trapezoid at (5, 0): 6
Distance from target shape to blue trapezoid at (5, 3): 3
Distance from target shape to cyan square at (1, 0): 4
Closest shape is the yellow square at (1, 4) with distance 2</think>
