Why does the narrator regard Antarctica as a place that expands one's understanding of Earth's past and present?

Answer: Antarctica preserves evidence of the ancient supercontinent Gondwana and therefore helps us understand the geological evolution of Earth. At the same time, its delicate ecosystem reveals how closely the planet's natural systems are connected and how human actions can disturb them. The continent thus links deep history with the urgent need for responsible environmental behaviour.

Solution

The answer should connect Antarctica's geological record with its ecological importance. A strong response also explains how the continent encourages a broader understanding of Earth's history and humanity's responsibility towards the environment.
