Tropical plant fossils have been found in cold Arctic islands where they cannot survive in the present-day climate of this area. According to Wegener's theory, how were these ancient tropical plants able to survive in Arctic islands?

Wegener’s theory of continental drift says that continents and islands have moved over time. The Arctic islands could once have been at lower latitudes, nearer the equator, where the climate was warm enough for tropical plants to grow. So the correct choice is “Arctic islands were closer to the equator in the past.”
