Answer

Brief Explanations:

The first paragraph presents the surprising fact that the mid - ocean ridge system is the most extensive mountain chain on Earth (a fact that might be unknown to many as more familiar mountain ranges like the Himalayas are mentioned first). The second paragraph then gives more details about this mid - ocean ridge system such as its length (65,000 kilometers), its location (mostly deep underwater with an average water depth to the top of the ridge of 2,500 meters). It does not downplay its significance (so the first option is wrong) and there is no mention of a theory from scientists (so the second option is wrong).

Answer:

They point out a surprising fact and then give more details about it.
