Article: After a new wave of UN sanctions, on 11 March 2013, North Korea claimed that it had invalidated the 1953 armistice. On 13 March 2013, North Korea confirmed it ended the 1953 Armistice and declared North Korea "is not restrained by the North-South declaration on non-aggression". On 30 March 2013, North Korea stated that it had entered a "state of war" with South Korea and declared that "The long-standing situation of the Korean peninsula being neither at peace nor at war is finally over". Speaking on 4 April 2013, the U.S. Secretary of Defense, Chuck Hagel, informed the press that Pyongyang had "formally informed" the Pentagon that it had "ratified" the potential usage of a nuclear weapon against South Korea, Japan and the United States of America, including Guam and Hawaii. Hagel also stated that the United States would deploy the Terminal High Altitude Area Defense anti-ballistic missile system to Guam, because of a credible and realistic nuclear threat from North Korea.

Article: At these higher altitudes, the plants tend to form isolated cushions. In the Alps, several species of flowering plants have been recorded above 4,000 m (13,120 ft), including Ranunculus glacialis, Androsace alpina and Saxifraga biflora. The Eritrichium nanum, commonly known as the King of the Alps, is the most elusive of the alpine flowers, growing on rocky ridges at 2,600 to 3,750 m (8,530 to 12,303 ft). Perhaps the best known of the alpine plants is the Edelweiss which grows in rocky areas and can be found at altitudes as low as 1,400 m (4,593 ft) and as high as 3,400 m (11,155 ft). The plants that grow at the highest altitudes have adapted to conditions by specialization such as growing in rock screes that give protection from winds.

Question: Ranunculus glacialis have been recorded to have been found how far in the alps?
Ans: above 4,000 m

Article: In England, the Royal Society of London also played a significant role in the public sphere and the spread of Enlightenment ideas. It was founded by a group of independent scientists and given a royal charter in 1662. The Society played a large role in spreading Robert Boyle's experimental philosophy around Europe, and acted as a clearinghouse for intellectual correspondence and exchange. Boyle was "a founder of the experimental world in which scientists now live and operate," and his method based knowledge on experimentation, which had to be witnessed to provide proper empirical legitimacy. This is where the Royal Society came into play: witnessing had to be a "collective act", and the Royal Society's assembly rooms were ideal locations for relatively public demonstrations. However, not just any witness was considered to be credible; "Oxford professors were accounted more reliable witnesses than Oxfordshire peasants." Two factors were taken into account: a witness's knowledge in the area; and a witness's "moral constitution". In other words, only civil society were considered for Boyle's public.

Question: In what year was the Royal Society of London given a royal charter?
Ans: 1662

Article: Domestic dogs have been selectively bred for millennia for various behaviors, sensory capabilities, and physical attributes. Modern dog breeds show more variation in size, appearance, and behavior than any other domestic animal. Dogs are predators and scavengers, and like many other predatory mammals, the dog has powerful muscles, fused wrist bones, a cardiovascular system that supports both sprinting and endurance, and teeth for catching and tearing.

Question: What bones in dog legs are fused?
Ans:
wrist
