1. I think "the Bermuda Triangle is no more statistically dangerous than other areas of the open ocean." means "the Bermuda Triangle is as statistically dangerous as other areas of the open ocean", which is an equal comparison. And in this case of "no more A than B", B is usually an unimportant thing, isn't it?
2. How does "magnetic north" differ from "North Pole"?
혀35)For many years, the Bermuda Triangle has been known as a place where boats and aircraft mysterioulsy disappear...Actually the Bermuda Triangle is no more statistically dangerous than other areas of the open ocean...Near Miami, the earth's magnetic field causes compasses to point to the North Pole, instead of the 0 degree Magnetic North.
1. It would be more natural to put 'statistically' before 'no more dangerous'.
It is just as dangerous as other areas — not more so.
