Reading：The short-faced bears caught fast-running animals such as deer, for the strong and long legs enabled bears to run fast too.
Listening：The fast-running animals often suddenly changed directions and made sharp turns. Being so heavy, bears needed time to slow down and turned direction when running, so they could not catch those animals.

Reading：Bears were scavengers, eating the dead animal bodies, and they were big enough to threaten or fight off other scavengers like wolves.
Listening：No records suggest that the bears had the kind of distinct marks on the teeth that are characteristic of scavengers. That marks on the teeth were specifically used to gnaw the hard bones of the dead animals.
