Problem: Uranium:

Uranium metal heated to 250 to 300 °C (482 to 572 °F) reacts with hydrogen to form uranium hydride. Even higher temperatures will reversibly remove the hydrogen. This property makes uranium hydrides convenient starting materials to create reactive uranium powder along with various uranium carbide, nitride, and halide compounds. Two crystal modifications of uranium hydride exist: an α form that is obtained at low temperatures and a β form that is created when the formation temperature is above 250 °C.

Above what temperature is the β form of uranium hydride destroyed?

Problem: Poultry is the second most widely eaten type of meat in the world, accounting for about 30% of total meat production worldwide compared to pork at 38%. Sixteen billion birds are raised annually for consumption, more than half of these in industrialised, factory-like production units. Global broiler meat production rose to 84.6 million tonnes in 2013. The largest producers were the United States (20%), China (16.6%), Brazil (15.1%) and the European Union (11.3%). There are two distinct models of production; the European Union supply chain model seeks to supply products which can be traced back to the farm of origin. This model faces the increasing costs of implementing additional food safety requirements, welfare issues and environmental regulations. In contrast, the United States model turns the product into a commodity.
What country has never had poultry before?

Although there were a number of department stores in Australia for much of the 20th Century, including chains such as Grace Bros. and Waltons, many disappeared during the 1980s and 1990s. Today Myer and David Jones, located nationally, are practically the national department stores duopoly in Australia. When Russian-born migrant, Sidney Myer, came to Australia in 1899 he formed the Myer retail group with his brother, Elcon Myer. In 1900, they opened the first Myer department store, in Bendigo, Victoria. Since then, the Myer retail group has grown to be Australia's largest retailer. Both, Myer and David Jones, are up-market chains, offering a wide variety of products from mid-range names to luxury brands. Other retail chain stores such as Target (unrelated to the American chain of the same name), Venture (now defunct), Kmart and Big W, also located nationally, are considered to be Australia's discount department stores. Harris Scarfe, though only operating in four states and one territory, is a department store using both the large full-line and small discount department store formats. Most department stores in Australia have their own credit card companies, each having their own benefits while the discount department stores do not have their own credit card rights.
Where did the Myer Retail Group open its last store?

Context and question: The papal bull defining the dogma, Ineffabilis Deus, mentioned in particular the patrististic interpretation of Genesis 3:15 as referring to a woman, Mary, who would be eternally at enmity with the evil serpent and completely triumphing over him. It said the Fathers saw foreshadowings of Mary's "wondrous abundance of divine gifts and original innocence" "in that ark of Noah, which was built by divine command and escaped entirely safe and sound from the common shipwreck of the whole world; in the ladder which Jacob saw reaching from the earth to heaven, by whose rungs the angels of God ascended and descended, and on whose top the Lord himself leaned; in that bush which Moses saw in the holy place burning on all sides, which was not consumed or injured in any way but grew green and blossomed beautifully; in that impregnable tower before the enemy, from which hung a thousand bucklers and all the armor of the strong; in that garden enclosed on all sides, which cannot be violated or corrupted by any deceitful plots; in that resplendent city of God, which has its foundations on the holy mountains; in that most august temple of God, which, radiant with divine splendours, is full of the glory of God; and in very many other biblical types of this kind."
According to the document what did the forebears already have knowledge of before Mary came about ?
Answer: the Fathers saw foreshadowings of Mary's "wondrous abundance of divine gifts and original innocence


Question: A culinary staple of North Carolina is pork barbecue. There are strong regional differences and rivalries over the sauces and methods used in making the barbecue. The common trend across Western North Carolina is the use of premium grade Boston butt. Western North Carolina pork barbecue uses a tomato-based sauce, and only the pork shoulder (dark meat) is used. Western North Carolina barbecue is commonly referred to as Lexington barbecue after the Piedmont Triad town of Lexington, home of the Lexington Barbecue Festival, which attracts over 100,000 visitors each October. Eastern North Carolina pork barbecue uses a vinegar-and-red-pepper-based sauce and the "whole hog" is cooked, thus integrating both white and dark meat.
Is there an answer to this question: What cut of pork do those in western North carolina prefer for BBQ?

Answer: Boston butt


Problem: Thuringia:

The landscapes of Thuringia are quite diverse. The far north is occupied by the Harz mountains, followed by the Goldene Aue, a fertile floodplain around Nordhausen with the Helme as most important river. The north-west includes the Eichsfeld, a hilly and sometimes forested region, where the Leine river emanates. The central and northern part of Thuringia is defined by the 3000 km² wide Thuringian Basin, a very fertile and flat area around the Unstrut river and completely surrounded by the following hill chains (clockwise from the north-west): Dün, Hainleite, Windleite, Kyffhäuser, Hohe Schrecke, Schmücke, Finne, Ettersberg, Steigerwald, Thuringian Forest, Hörselberge and Hainich. Within the Basin the smaller hill chains Fahner Höhe and Heilinger Höhen. South of the Thuringian Basin is the Land's largest mountain range, marked by the Thuringian Forest in the north-west, the Thuringian Highland in the middle and the Franconian Forest in the south-east. Most of this range is forested and the Großer Beerberg (983 m) is Thuringia's highest mountain. To the south-west, the Forest is followed up by Werra river valley, dividing it from the Rhön Mountains in the west and the Grabfeld plain in the south. Eastern Thuringia, commonly described as the area east of Saale and Loquitz valley, is marked by a hilly landscape, rising slowly from the flat north to the mountainous south. The Saale in the west and the Weiße Elster in the east are the two big rivers running from south to north and forming densely settled valleys in this area. Between them lies the flat and forested Holzland in the north, the flat and fertile Orlasenke in the middle and the Vogtland, a hilly but in most parts non-forested region in the south. The far eastern region (east of Weiße Elster) is the Osterland or Altenburger Land along Pleiße river, a flat, fertile and densely settled agricultural area.
