When Eratosthenes measured the angles cast by the Sun at Syene and at Alexandria, the difference in angle was 7 degrees. If he had measured the difference to be 10 degrees instead of 7, which of the following statements would be true?
1) The distance between Syene and Alexandria would be greater.
2) The distance between Syene and Alexandria would be smaller.
3) The distance between Syene and Alexandria would remain the same.
4) The angle cast by the Sun at Syene would be greater than the angle cast at Alexandria.
