3 Why is the position of the sun and various stars useful for working out latitude?

In the year between 1405 and 1433, seven large treasure fleets sailed westwards on voyages of trade and exploration. Under the command of Zheng He, the fleets set sail from the South China Sea across the Indian Ocean to the Red Sea, and then traveled further south, discovering the eastern coast of Africa.
He renewed relations with the Kingdoms of the East African coast. One African king sent the Ming emperor a royal present: two giraffes.
About 700 years ago a young trader from Italy took a long trip to Cathay. Cathay is known as China today. He went with his father and uncle, who had traveled there once before. They stayed in China for about two decades. The young man's name was Marco Polo. He was liked by the leader in China at the time.
He knew four languages and traveled around the kingdom for the leader. When Marco Polo returned to Italy, he dictated his story to a writer. He told of the Chinese postal system, paper money, and the use of coal as fuel.

Reading
The four basic instruments for navigation: Sinan, Inch Astrolabe, Sextant and nautical map.
Sinan, the ancient Chby Zhang Heng in the Han dynasty. It is made up of a bronze foundation (青铜地盘) and magnetic spoon(磁勺) which is made of natural magnet, positioned right in the central of the foundation.
sextant
The sextant is a navigational instrument for measuring the angle between the horizon and some object in the sky. First a sailor looks at the horizon through an eyepiece. At the same time he can see light from the sun or a star reflected off a small mirror on top of the instrument, onto a second mirror and into the eyepiece.
2. Which do you think was easier to work out: latitude or longitude? Latitude, because it was used to measure how far you had traveled from land on a straight line. It was discovered a long time before longitude.
