Passage Summary: Big animals eat a ton, so when the weather ruins the food supply, they die out faster than little animals who don't need as much to survive.

Reasoning: Large animals require massive food intake, making them vulnerable during climate shifts, whereas small animals need less food to maintain populations.

Analysis: Treat the premises as absolute facts and look for a statement that follows logically from them. The stimulus establishes a direct link between body size, food requirements, and extinction risk during environmental stress. An ideal answer will likely suggest that smaller food requirements provide a survival advantage during periods of climatic deterioration.
