A Correct answer
Explanation

Northern hemisphere summer is slightly longer than southern hemisphere summer. This is because Earth is closer to the sun (perihelion) in January, during southern summer, making it move faster and shortening that season. Conversely, Earth is farther (aphelion) in July during northern summer, moving slower and lengthening it. The difference is several days.
