Which item would serve as evidence to identify who dumped pollutants on the island?

• A. Who dumped the hazardous materials
• B. When they dumped it
• C. Where the materials came from
• D. How it was dumped

Answer: (A)

To identify who dumped pollutants, you need evidence that directly links a person to the act. This kind of evidence answers the question of who performed the dumping, making it the most decisive for identifying the culprit. Examples include eyewitness reports naming a person, surveillance footage showing the act, fingerprints or other traces at the dumping site that can be matched to someone, or a confession.

Information about when the dumping occurred, where the materials came from, or how the dumping was carried out helps reconstruct the incident and narrow down possibilities, but on their own they don’t prove who did it.
