Problem: Queen (band):

In summer of 1986, Queen went on their final tour with Freddie Mercury. A sold-out tour in support of A Kind of Magic, once again they hired Spike Edney, leading to him being dubbed the unofficial fifth member. The Magic Tour's highlight was at Wembley Stadium in London and resulted in the live double album, Queen at Wembley, released on CD and as a live concert DVD, which has gone five times platinum in the US and four times platinum in the UK. Queen could not book Wembley for a third night, but they did play at Knebworth Park. The show sold out within two hours and over 120,000 fans packed the park for what was Queen's final live performance with Mercury. Queen began the tour at the Rasunda Stadium in Stockholm, Sweden, and during the tour the band performed a concert at Slane Castle, Ireland, in front of an audience of 95,000, which broke the venue's attendance record. The band also played behind the Iron Curtain when they performed to a crowd of 80,000 at the Nepstadion in Budapest, in what was one of the biggest rock concerts ever held in Eastern Europe. More than one million people saw Queen on the tour400,000 in the United Kingdom alone, a record at the time.

Problem: Geography of the United States:

By total area (water as well as land), the United States is either slightly larger or smaller than the People's Republic of China, making it the world's third or fourth largest country. China and the United States are smaller than Russia and Canada in total area, but are larger than Brazil. By land area only (exclusive of waters), the United States is the world's third largest country, after Russia and China, with Canada in fourth. Whether the US or China is the third largest country by total area depends on two factors: (1) The validity of China's claim on Aksai Chin and Trans-Karakoram Tract. Both these territories are also claimed by India, so are not counted; and (2) How US calculates its own surface area. Since the initial publishing of the World Factbook, the CIA has updated the total area of United States a number of times.

Which country is the worlds fourth largest?

A: Canada

Problem: Endangered Species Act:

This first list is referred to as the "Class of '67" in The Endangered Species Act at Thirty, Volume 1, which concludes that habitat destruction, the biggest threat to those 78 species, is still the same threat to the currently listed species. It included only vertebrates because the Department of Interior's definition of "fish and wildlife" was limited to vertebrates. However, with time, researchers noticed that the animals on the endangered species list still were not getting enough protection, thus further threatening their extinction. The endangered species program was expanded by the Endangered Species Act of 1969.

What threat towards species has been neutralized?
