Q:I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "In the Miocene Epoch the mountains underwent severe erosion because of glaciation, which was noted in the mid-19th century by naturalist Louis Agassiz who presented a paper proclaiming the Alps were covered in ice at various intervals—a theory he formed when studying rocks near his Neuchâtel home which he believed originated to the west in the Bernese Oberland. Because of his work he came to be known as the "father of the ice-age concept" although other naturalists before him put forth similar ideas."?
A:
What was Louis Agassiz's theory about the ice covering the Alps?
