Why is A right?
I thought A was general for many reasons, and I donâ€™t see support for it in the passage.
First, the ages of other rocks arenâ€™t even mentioned in the passage. So, even if could say the oldest submarine basalt rock, how could I make that jump to the rest of the rocks in the ocean?
And how would I know that the rock closest to the continents are those furthest from the global mid-ocean ridge? I donâ€™t even have information of where mid-ocean ridge is located in the text. I mean am I supposed to assume that â€œmidâ€ means middle of continents?
I think there is more support for C. If I know magnetite locally distorts compasses on land, and magnetite is contained in the rock making up much of the ocean floor, than I have some reason to believe compass reading are more likely to be distorted at sea.
