Which event is associated with Prince William Sound's Alaska oil history?

• A. Exxon Valdez
• B. Three Mile Island
• C. Chernobyl
• D. Deepwater Horizon

Answer: (A)

Exxon Valdez is the event tied to Prince William Sound's oil history. In 1989, the tanker Exxon Valdez ran aground on Bligh Reef, unleashing millions of gallons of crude oil into Prince William Sound. The spill devastated coastal ecosystems—affecting wildlife like seals, sea otters, seabirds, and fish runs—that many Alaska Native communities rely on for food and cultural practices. It also spurred major changes in oil transportation safety, spill response, and liability laws, shaping how oil development is managed in Alaska and how traditional ways of life are protected. The other events listed are unrelated to Alaska’s oil history: nuclear accidents in Pennsylvania and Ukraine, and a Gulf of Mexico oil spill.
