Question

Quizplus · Accepted Answer

The passage of stupendous floods resulting from failed ice dams in front of the largest glacial lakes is still recorded in multiple ways, such as lake sediments, countryside stripped of all soil and sediment cover, abandoned waterfalls, and a system of braided channels now left mostly dry. Therefore, option E, i.e., "all of these" is the best choice.
