Scientists calculated that the asteroid, traveling at 46000miles an hour, is on an elliptical path that orbits the sun once a year and regularly brings it back toward Earth.
(a) hour, is on an elliptical path that orbits the Sun once a year  and regularly brings it
(b) hour, is orbiting the Sun once a year on an elliptical path that regularly brings it
(c) hour, once a year orbits the Sun, regularly bringing it on an elliptical path
(d) hour and orbiting the Sun once a year on an elliptical path, regularly bringing it
(e) hour, orbits the Sun on an elliptical path once a year and that regularly brings it

这道题目的答案是B。但我觉得C更好，理由如下：首先，B的时态用的不好，陈述一个客观的事实，应该用一般现在时。其次，我觉得原文的逻辑有点问题，轨道是不能绕着太阳转的，而且我觉得把小行星拉回来的应该是太阳的引力（这个不是物理常识吗？），不是轨道，所以C选项很好的符合时态以及逻辑的正确。
求各位NN指点（初次发帖，细节上不到位的地方请多多包含哈）。
