Answer to Question 1

Paleomagnetic evidence indicates that glaciers existed at or near the equator during this time. Additionally, banded iron formations indicate an anoxic deep ocean, which could have resulted from a separation of the ocean from the atmosphere resulting from the ice, and the placement of cap carbonates above glacial layers agrees with the CO2 build-up that could have been the means of escape from this Snowball Earth episode.

Answer to Question 2

Answer: A
