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