Question

Which sentence best expresses the central idea of the entire article?

A "One species every 70,000 years! That's the rate at which plants and animals once
colonized the Hawaiian Islands."
B "It took time, but these barren new 'worlds,' risen from the sea and born of fire, finally
surrendered to the slow but persistent assault of life."
С "Remote and alone in the heart of the North Pacific, Hawaii is the most isolated island
group on Earth."
D "They had to struggle to survive on harsh Hawaii, feeding on organic debris tossed to
shore by wind and wave."

Answer 1

The choice should be B as it tells both about how life colonized the island as well as the other point.
