Evil aliens have decided to kill everyone on Earth! Fortunately, they've given you two minutes to save as many as you can. All you have to do is name a country to save everyone in it.
For D.C. I tried the White House, the US Capitol, Arlington National Cemetery with the Tomb of the Unknown Soldier and JFK graves, the Washington Monument, the Lincoln and Jefferson Memorials, the Smithsonian, and the Pentagon. Sigh.
For Hawaii I tried the Arizona Memorial and Pearl Harbor Memorial before finally getting the correct answer. The percentage may be so low because people are having trouble getting the entire answer.
