og12-100 是不是有run-on的问题

Like the planets, the stars are in motion, some of them at tremendous speeds, but they are so far away from Earth that their apparent positions in the sky do not change enough for their movement to be observed during a single human lifetime.

我已经把正确选项B选项还原了，老实说，我觉得每项都有run-on的问题，请大家帮我看看斟酌一下。
