Summarize Argument

The author concludes that it was likely that the extinct mammal Megatherium was a predator. As support, the author cites the fact that Megatherium had a short olecranon process. Predators tend to have short olecranon processes because they need to move their forelimbs quickly, and shorter olecranon processes allow faster forelimb movement.

Identify and Describe Flaw

The stimulus only tells us that predators tend to have short olecranon processes. The stimulus does not say that only predators have short olecranon processes. With the information given, it can still be the case that animals that aren’t predators also have short olecranon processes.
