  1. in the summer time the days are longer and warmer.

  3. in the spring time the days are shorter and hotter.

  4. in the summer time the days are shorter and colder.

A Correct answer
Explanation

The variation in day length and temperature throughout the year (such as longer, warmer days in summer) is direct evidence of the Earth's axial tilt. If there were no tilt, day length and seasonal temperatures would remain constant year-round.
