问题      Copernicus was born in Torun, Poland, on Februry 19, 1473. Little is known about his early life except that his father died when he was 10. An uncle adopted him, his two sisters and his brother. The uncle saw to it that the two boys received a good education. Copernicus went to the University of Cracow. There he studied such subjects as Lat in, mathematics and astronomy. It was probably at that time that he changed his Polish name, Niklas Koppernigk, to the Latin form of Nicolaus Copernicus. In 1496 Copernicus went to Italy, where he spent the next 10 years studying at various universities.
     In Copernicus’ time, people still believed that all things—the sun, the stars, and the planets—moved around the earth. It was an old belief that few men had ever questioned. Aristotle bad based his theory of astronomy on this belief. Because the church had long been the center of learning, the theory was also linked to religious beliefs.
     In 1506, Copernicus returned to his homeland. A few years later, he began to work for the church. All those years, Copernicus carded on his work in astronomy. He had just the most basic equipment and, like other scientists of his day, made observations with only his eyes. Still, using mathematics and logic, Copernicus worked out a different theory that the planets go around the sun.
     Copernicus did not announce his ideas. He did not want to make trouble. But he could not hide the scientific troth. So he talked about his theory with his friends, who strongly advised him to have his works published. His great book On the Revolution of the Heavenly Bodies, appeared at the very end of his life. Copernicus saw the first copy on the day when he died, May 24,1543.
Copernicus developed his theory ______.
选项 A、by using various telescopes
B、based on Aristotle’s beliefs
C、through observations and reasoning
D、under the encouragement of his friends
答案C
解析 由文章第三段最后二句可知，他是通过观察和推理，形成自己的理论的。
