Answer to Question 1

C

Answer to Question 2

Eratosthenes read about a well in Syene where sunlight reached the bottom at noon on the summer solstice, meaning that the Sun's rays were perfectly vertical. He measured the angle of a shadow cast by a column in Alexandria on the summer solstice, and used this angle to calculate the distance between the two cities, as a fraction of Earth's circumference. As the distance was already known, he could solve for the total circumference of Earth.
