Many people believe the Bering Strait was once a land bridge connecting which two regions?

The Bering Strait is widely understood to have once served as a land bridge that connected Russia and Alaska. This land bridge, known as Beringia, existed during the last Ice Age when sea levels were significantly lower, allowing prehistoric peoples and animals to migrate between the two land masses. This migration was a critical factor in the spread of early human populations into the Americas. The geographical and historical significance of this connection reinforces the validity of the answer, as it reflects a well-documented migration route that has shaped human history. The other choices do not align with the established understanding of prehistoric migration paths or the geographic relationship between the regions mentioned.
