With the introduction of the blast furnace to Europe in the Middle Ages, pig iron was able to be produced in much higher volumes than wrought iron. Because pig iron could be melted, people began to develop processes of reducing the carbon in the liquid pig iron to create steel. Puddling was introduced during the 1700s, where molten pig iron was stirred while exposed to the air, to remove the carbon by oxidation. In 1858, Sir Henry Bessemer developed a process of steel-making by blowing hot air through liquid pig iron to reduce the carbon content. The Bessemer process was able to produce the first large scale manufacture of steel. Once the Bessemer process began to gain widespread use, other alloys of steel began to follow. Mangalloy, an alloy of steel and manganese exhibiting extreme hardness and toughness, was one of the first alloy steels, and was created by Robert Hadfield in 1882.
In what year did Henry Bessemer create Mangalloy?
A: unanswerable

Motorsport racecourses and events were banned in Switzerland following the 1955 Le Mans disaster with exception to events such as Hillclimbing. During this period, the country still produced successful racing drivers such as Clay Regazzoni, Sebastian Buemi, Jo Siffert, Dominique Aegerter, successful World Touring Car Championship driver Alain Menu, 2014 24 Hours of Le Mans winner Marcel Fassler and 2015 24 Hours Nurburgring winner Nico Muller. Switzerland also won the A1GP World Cup of Motorsport in 200708 with driver Neel Jani. Swiss motorcycle racer Thomas Luthi won the 2005 MotoGP World Championship in the 125cc category. In June 2007 the Swiss National Council, one house of the Federal Assembly of Switzerland, voted to overturn the ban, however the other house, the Swiss Council of States rejected the change and the ban remains in place.
Who rejected the 2007 vote to overturn the motorsport ban in Switzerland?
A: Swiss Council of States

White LEDs can also be made by coating near-ultraviolet (NUV) LEDs with a mixture of high-efficiency europium-based phosphors that emit red and blue, plus copper and aluminium-doped zinc sulfide (ZnS:Cu, Al) that emits green. This is a method analogous to the way fluorescent lamps work. This method is less efficient than blue LEDs with YAG:Ce phosphor, as the Stokes shift is larger, so more energy is converted to heat, but yields light with better spectral characteristics, which render color better. Due to the higher radiative output of the ultraviolet LEDs than of the blue ones, both methods offer comparable brightness. A concern is that UV light may leak from a malfunctioning light source and cause harm to human eyes or skin.
What device also works in a similar way as non-NUV LEDs?
A: unanswerable

A project that is proceeding is the creation of The Queen's Diamond Jubilee Galleries in the medieval triforium of the abbey. The aim is to create a new display area for the abbey's treasures in the galleries high up around the abbey's nave. To this end a new Gothic access tower with lift has been designed by the abbey architect and Surveyor of the Fabric, Ptolemy Dean. It is planned that the new galleries will open in 2018.
What will be created in the medieval biforium?
A:
unanswerable
