Geography · Globe: Latitudes and Longitudes

Ms. Rose asks her class, 'What would happen if humans decided to keep a single clock time for the whole world, without separate time zones?' Four students respond as follows: Student 1: Longitudes would no longer be of use. Student 2: The seasons in different parts of the world would change. Student 3: All parts of the world would have day and night together. Student 4: For some countries, morning sunrise would be at 5 o'clock clock-time, for some at 17 o'clock clock-time, and so on. Arrange the 4 students in INCREASING order of conceptual clarity.
