答案B:soo too are modems, the devices that allow
但OG解释说:either that allow or allowing would be correct.

阴影部分是第一个句子,“,and”连接的是第二个句子,第二个句子中已有一个主谓完整的句子了so too are modems(虽然是倒装),这样的结构是正确的,可是接着“,”又来一个“they are”主谓完整的句子,似乎就不正确,(,不能连接2个主谓完整的句子)即run-on,所以只能是改成同位语从句。
个人理解,欢迎讨论
顶。
个人认为 and so too are modems与computer are...平行,而不是与faster,powerful,reliable平行,the devices...同位语修饰modems,所以A存在run-on的问题
