[单项选择] As countless photos from space can prove, the Earth is round the "Blue Marble," as astronauts have affectionately dubbed it. Appearances, however, can be deceiving. Planet Earth is not, in fact, perfectly round. This is not to say the Earth is flat. Well before Columbus sailed the ocean, Aristotle and other ancient Greek scholars proposed that Earth was round.

Isaac Newton first proposed that Earth was not perfectly round. Instead, he suggested it was an oblate spheroid(扁球体) a sphere that is squashed at its poles and swollen at the equator. He was correct and, because of this bulge, the distance from Earth’’s center to sea level is roughly 21 kilometers greater at the equator than at the poles.
Our globe, however, is not even a perfect oblate

C. to prove that Earth is not perfectly round
