There are 6 shapes on a 5x5 grid. Which shape is closest to the red 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: red rectangle at (2, 4)
Distance from target shape to yellow trapezoid at (3, 4): 1
Distance from target shape to brown square at (1, 1): 4
Distance from target shape to green square at (1, 4): 1
Distance from target shape to orange trapezoid at (3, 0): 5
Distance from target shape to blue rectangle at (1, 3): 2
Closest shape is the yellow trapezoid at (3, 4) with distance 1</think>
