Article: The largest mammal to live in the highest altitudes are the alpine ibex, which have been sighted as high as 3,000 m (9,843 ft). The ibex live in caves and descend to eat the succulent alpine grasses. Classified as antelopes, chamois are smaller than ibex and found throughout the Alps, living above the tree line and are common in the entire alpine range. Areas of the eastern Alps are still home to brown bears. In Switzerland the canton of Bern was named for the bears but the last bear is recorded as having been killed in 1792 above Kleine Scheidegg by three hunters from Grindelwald.

Question: Where do the ibex live?
Ans: in caves

Article: Outdoor events and festivals are held including the annual British Firework Championships in August, which attracts tens of thousands of people across the waterfront. In August 2006 the world record for the most amount of simultaneous fireworks was surpassed, by Roy Lowry of the University of Plymouth, over Plymouth Sound. Since 1992 the Music of the Night has been performed in the Royal Citadel by the 29 Commando Regiment and local performers to raise money for local and military charities.

Question: Who broke the world record for simultaneous fireworks?
Ans: Roy Lowry

Article: The Northwestern Interdisciplinary Law Review is a scholarly legal publication published annually by an editorial board of Northwestern University undergraduates. The journal's mission is to publish interdisciplinary legal research, drawing from fields such as history, literature, economics, philosophy, and art. Founded in 2008, the journal features articles by professors, law students, practitioners, and undergraduates. The journal is funded by the Buffett Center for International and Comparative Studies and the Office of the Provost.

Question: What journal was founded in 2008 that features articles by professors and law students?
Ans: The Northwestern Interdisciplinary Law Review

Article: While the use of iron started to become more widespread around 1200 BC, mainly because of interruptions in the trade routes for tin, the metal is much softer than bronze. However, very small amounts of steel, (an alloy of iron and around 1% carbon), was always a byproduct of the bloomery process. The ability to modify the hardness of steel by heat treatment had been known since 1100 BC, and the rare material was valued for the manufacture of tools and weapons. Because the ancients could not produce temperatures high enough to melt iron fully, the production of steel in decent quantities did not occur until the introduction of blister steel during the Middle Ages. This method introduced carbon by heating wrought iron in charcoal for long periods of time, but the penetration of carbon was not very deep, so the alloy was not homogeneous. In 1740, Benjamin Huntsman began melting blister steel in a crucible to even out the carbon content, creating the first process for the mass production of tool steel. Huntsman's process was used for manufacturing tool steel until the early 1900s.

Question: Heat treatment of steel has been know since what time?
Ans:
1100 BC
