Explanation:

1. For the first drop - down (after "A carcinogen is a substance known to cause"): The definition of a carcinogen is a substance that causes cancer. So we choose "cancer".
2. For the second drop - down (after "A hazardous material is a substance that has the potential to cause"): Hazardous materials can cause injury. "Side effects" are more related to medications, and "adverse effects" is a bit too general here compared to "injury" for hazardous materials. So we choose "injury".

Answer:

• A carcinogen is a substance known to cause cancer.
• A hazardous material is a substance that has the potential to cause injury.
