The correct Answer is:
To determine the percentage of living species that became extinct during the Permian-Triassic period, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Context**: The Permian-Triassic extinction event, which occurred around 252 million years ago, is known as the largest mass extinction in Earth's history. 2. **Identify the Extinction Rate**: Research indicates that during this event, approximately 90% to 96% of all species on Earth went extinct. 3. **Focus on the Question**: The question specifically asks for the percentage of living species that became extinct during this period. 4. **Select the Correct Percentage**: Given the data, the extinction rate of 90% to 96% indicates that the correct answer must fall within this range. 5. **Evaluate the Options**: The options provided are: - 56% - 78% - 87% - 96% Since we know that 90% to 96% of species became extinct, the only option that fits this criterion is **96%**. 6. **Conclusion**: Therefore, the percentage of living species that became extinct during the Permian-Triassic period is **96%**. ### Final Answer: The percentage of living species that became extinct during the Permian-Triassic period is **96%**. ---
