A. Finding the shortest flight path for an airplane
This problem is well-suited for a computer because it involves complex calculations, optimization algorithms, and the analysis of multiple variables (such as distance, weather conditions, air traffic, etc.) to determine the most efficient route. Computers excel at processing large amounts of data quickly and finding optimal solutions.
The other options (B, C, and D) involve subjective judgments and complex social issues that are not as easily solved by computational methods alone.
