Which of these conditions would most likely be shown in the fossil record as a reason for mass extinctions?

OPTIONS:
- increased competition for resources
- falling sea levels and global cooling
- organisms with beneficial traits
- increased solar activity
falling sea levels and global cooling
Vilket av dessa tillstånd skulle med största sannolikhet visas i fossilens vittnesbörd som en orsak till massutdöenden? Alternativ: - ökad konkurrens om resurser - fallande havsnivåer och global kylning - organismer med gynnsamma egenskaper - ökad solaktivitet
