问题 Which of the following statements is true according to the first paragraph?
Which fact can prove what Newton proposed was right?
选项 A、The departing ships seemed to be smaller and smaller when they sailed away.
B、The greater a concentration of mass is at the poles, the stronger its gravitational pull.
C、The length from Earth’s center to sea level at the equator is longer than that at the poles.
D、The changes in the rising of a few millimeters on Earth’s surface detected by modern devices.
答案C
解析 根据题干中Newton可以定位到第二段。这段提到了牛顿第一个提出了地球并不是一个绝对的球体，而是一个扁平的球体，在两极地区收缩了，而在赤道地区又凸起了。牛顿是正确的，正是因为赤道地区的凸起，地球中心到海平面的距离在赤道地区要比在两极地区长21千米。也就是说，地球中心到海平面的距离在赤道地区要比在两极地区长这个事实能够证明牛顿是正确的。驶离的船只开走时看起来越来越小这个事实不能证明牛顿是正确的，故可排除A；质量越集中，重力越强，造成了地球表面的凹凸不平，但这不能证明牛顿是正确的，故可排除B；仪器探测到的地球表面几毫米的起伏这个事实不能证明牛顿是正确的，故可排除D。
