{'summer season': [0, 0, 0, 1], 'winter season': [2, 0, 2, 7], 'duration': [0, 0, 1, 0], 'southern hemisphere': [0, 0, 2, 2], 'northern hemisphere': [3, 0, 0, 2], 'day': [0, 0, 1, 0]}

The correct statement is option 1, which states that in the summer season, the duration of the day is more in the northern hemisphere.

To understand why this statement is correct, we need to consider the tilt of the Earth`s axis and how it affects the length of day and night. The Earth`s axis is tilted relative to its orbit around the sun, and this tilt is what causes the change in seasons.

During the summer season, the northern hemisphere is tilted towards the sun. This means that sunlight is spread over a larger area and is more concentrated in the northern hemisphere. As a result, the length of daylight in the northern hemisphere is longer during the summer season.

On the other hand, in the winter season, the northern hemisphere is tilted away from the sun. This leads to less sunlight reaching the northern hemisphere, resulting in shorter daylight hours compared to the summer season.

Option 2 is incorrect because in the winter season, the duration of the day is actually shorter in the northern hemisphere.

Option 3 is also incorrect because in the summer season, the duration of the day is longer, not shorter, in the northern hemisphere.

Option 4 is incorrect because it refers to the southern hemisphere, whereas the question specifically asks about the duration of day in the northern hemisphere
