Problem: The band's sixth studio album News of the World was released in 1977, which has gone four times platinum in the United States, and twice in the UK. The album contained many songs tailor-made for live performance, including two of rock's most recognisable anthems, "We Will Rock You" and the rock ballad "We Are the Champions", both of which became enduring international sports anthems, and the latter reached number four in the US. Queen commenced the News of the World Tour in October 1977, and Robert Hilburn of the Los Angeles Times called this concert tour the band's "most spectacularly staged and finely honed show".
How many times platinum did Queen's News of the World go?
---
Answer: four

The government planned to voluntarily evacuate four million peoplemostly women and childrenfrom urban areas, including 1.4 million from London. It expected about 90% of evacuees to stay in private homes, and conducted an extensive survey to determine available space. Detailed preparations for transporting them were developed. A trial blackout was held on 10 August 1939, and when Germany invaded Poland on 1 September a blackout began at sunset. Lights would not be allowed after dark for almost six years, and the blackout became by far the most unpopular aspect of the war for civilians, more than rationing.:51,106 The relocation of the government and the civil service was also planned, but would only have occurred if necessary so as not to damage civilian morale.:33
Why did the government and civil service not want to relocate during the war?
A: damage civilian morale

Context and question: Rapid environmental changes typically cause mass extinctions. More than 99 percent of all species, amounting to over five billion species, that ever lived on Earth are estimated to be extinct. Estimates on the number of Earth's current species range from 10 million to 14 million, of which about 1.2 million have been documented and over 86 percent have not yet been described. The total amount of related DNA base pairs on Earth is estimated at 5.0 x 1037, and weighs 50 billion tonnes. In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC (trillion tons of carbon).
How many species have ever lived on earth?
Answer: over five billion species

Question: Certain technological inventions of the period whether of Arab or Chinese origin, or unique European innovations were to have great influence on political and social developments, in particular gunpowder, the printing press and the compass. The introduction of gunpowder to the field of battle affected not only military organisation, but helped advance the nation state. Gutenberg's movable type printing press made possible not only the Reformation, but also a dissemination of knowledge that would lead to a gradually more egalitarian society. The compass, along with other innovations such as the cross-staff, the mariner's astrolabe, and advances in shipbuilding, enabled the navigation of the World Oceans, and the early phases of colonialism. Other inventions had a greater impact on everyday life, such as eyeglasses and the weight-driven clock.
Is there an answer to this question: Which invention with military applications helped bring about the nation state?

Answer: gunpowder

In general relativity, a vanishing stress-energy tensor implies, through Einstein field equations, the vanishing of all the components of the Ricci tensor. Vacuum does not mean that the curvature of space-time is necessarily flat: the gravitational field can still produce curvature in a vacuum in the form of tidal forces and gravitational waves (technically, these phenomena are the components of the Weyl tensor). The black hole (with zero electric charge) is an elegant example of a region completely "filled" with vacuum, but still showing a strong curvature.
What kind of electric charge does a vanishing stress-energy tensor have?
A:
unanswerable
