Answer 1

Indeed good sir (or ma'am), you are correct.

I did the quiz and surprisingly got them right! Turns out I don't have a smooth brain!

Answer 2

A volcanic eruption would likely cause the most geographic isolation, as the extreme heat would make it impossible to even get near anyone living nearby. If a lava flow were to create a wall between two areas, it would be nearly impossible to cross it until well after the lava had cooled from the thousands of degrees it is when it exits the earth.
