Question: Strasbourg's historic city centre, the Grande Ile (Grand Island), was classified a World Heritage site by UNESCO in 1988, the first time such an honour was placed on an entire city centre. Strasbourg is immersed in the Franco-German culture and although violently disputed throughout history, has been a bridge of unity between France and Germany for centuries, especially through the University of Strasbourg, currently the second largest in France, and the coexistence of Catholic and Protestant culture. The largest Islamic place of worship in France, the Strasbourg Grand Mosque, was inaugurated by French Interior Minister Manuel Valls on 27 September 2012.
Try to answer this question if possible: What is the second largest university in France?
Answer: University of Strasbourg
Question: The 2009 Human Development Report by UNDP was released on October 5, 2009, and covers the period up to 2007. It was titled "Overcoming barriers: Human mobility and development". The top countries by HDI were grouped in a new category called "very high human development". The report refers to these countries as developed countries. They are:

Question: The spectrum emitted by a blackbody radiator at temperatures of incandescent bulbs does not match the sensitivity characteristics of the human eye; the light emitted does not appear white, and most is not in the range of wavelengths at which the eye is most sensitive. Tungsten filaments radiate mostly infrared radiation at temperatures where they remain solid below 3,695 K (3,422 C; 6,191 F). Donald L. Klipstein explains it this way: "An ideal thermal radiator produces visible light most efficiently at temperatures around 6,300 C (6,600 K; 11,400 F). Even at this high temperature, a lot of the radiation is either infrared or ultraviolet, and the theoretical luminous efficacy (LER) is 95 lumens per watt." No known material can be used as a filament at this ideal temperature, which is hotter than the sun's surface. An upper limit for incandescent lamp luminous efficacy (LER) is around 52 lumens per watt, the theoretical value emitted by tungsten at its melting point.

Answer: unanswerable
Question: Between the 8th and 18th centuries, the use of glazed ceramics was prevalent in Islamic art, usually assuming the form of elaborate pottery. Tin-opacified glazing was one of the earliest new technologies developed by the Islamic potters. The first Islamic opaque glazes can be found as blue-painted ware in Basra, dating to around the 8th century. Another contribution was the development of stone-paste ceramics, originating from 9th century Iraq. Other centers for innovative ceramic pottery in the Old world included Fustat (from 975 to 1075), Damascus (from 1100 to around 1600) and Tabriz (from 1470 to 1550).
Try to answer this question if possible: Which ceramic glazing was developed by those potters which were Islamic?
Answer:
Tin-opacified glazing
