Often categorised with the New Wave of British Heavy Metal, in 1981 Def Leppard released their second album High 'n' Dry, mixing glam-rock with heavy metal, and helping to define the sound of hard rock for the decade. The follow-up Pyromania (1983), reached number two on the American charts and the singles "Photograph", "Rock of Ages" and "Foolin'", helped by the emergence of MTV, all reached the Top 40. It was widely emulated, particularly by the emerging Californian glam metal scene. This was followed by US acts like Motley Crue, with their albums Too Fast for Love (1981) and Shout at the Devil (1983) and, as the style grew, the arrival of bands such as Ratt, White Lion, Twisted Sister and Quiet Riot. Quiet Riot's album Metal Health (1983) was the first glam metal album, and arguably the first heavy metal album of any kind, to reach number one in the Billboard music charts and helped open the doors for mainstream success by subsequent bands.
When did Motley Crue's album Shout At The Devil come out?
A: 1983

Cladistics is a technique borrowed from biology, where it was originally named phylogenetic systematics by Willi Hennig. In biology, the technique is used to determine the evolutionary relationships between different species. In its application in textual criticism, the text of a number of different manuscripts is entered into a computer, which records all the differences between them. The manuscripts are then grouped according to their shared characteristics. The difference between cladistics and more traditional forms of statistical analysis is that, rather than simply arranging the manuscripts into rough groupings according to their overall similarity, cladistics assumes that they are part of a branching family tree and uses that assumption to derive relationships between them. This makes it more like an automated approach to stemmatics. However, where there is a difference, the computer does not attempt to decide which reading is closer to the original text, and so does not indicate which branch of the tree is the "root"which manuscript tradition is closest to the original. Other types of evidence must be used for that purpose.
What is the mathmatical basis for Cladistics?
A: unanswerable

At the beginning of World War I, East Prussia became a theatre of war when the Russian Empire invaded the country. The Russian Army encountered at first little resistance because the bulk of the German Army had been directed towards the Western Front according to the Schlieffen Plan. Despite early success and the capture of the towns of Rastenburg and Gumbinnen, in the Battle of Tannenberg in 1914 and the Second Battle of the Masurian Lakes in 1915, the Russians were decisively defeated and forced to retreat. The Russians were followed by the German Army advancing into Russian territory.
Why did the Russian army face such little resistance when moving through Prussia?
A: German Army had been directed towards the Western Front

A number of species of moths live in the Alps, some of which are believed to have evolved in the same habitat up to 120 million years ago, long before the Alps were created. Blue moths can commonly be seen drinking from the snow melt; some species of blue moths fly as high as 1,800 m (5,906 ft). The butterflies tend to be large, such as those from the swallowtail Parnassius family, with a habitat that ranges to 1,800 m (5,906 ft). Twelve species of beetles have habitats up to the snow line; the most beautiful and formerly collected for its colours but now protected is the Rosalia alpina. Spiders, such as the large wolf spider, live above the snow line and can be seen as high as 400 m (1,312 ft). Scorpions can be found in the Italian Alps.
What can be commonly seen drinking from the snow melt?
A:
Blue moths
