Which of the following is a human-made disaster?

• A. Drought
• B. Oil spill causing contamination
• C. Tornado causing damage
• D. Volcanic eruption

Answer: (B)

The key idea here is distinguishing disasters by their cause: human-made versus natural. An oil spill causing contamination is a human-made disaster because its initiating event comes from human activity—improper handling, accidents during extraction, transport, or storage—leading to widespread environmental and health harm that requires cleanup and response. The other options come from natural processes: drought is a natural deficit in precipitation and water supply (even if humans can influence it, the start is natural), a tornado forms from atmospheric conditions, and a volcanic eruption comes from geological activity deep in the Earth. So the oil spill is the best example of a human-made disaster.
