Problem: Hyderabad:

Although not a centre for handicrafts itself, the patronage of the arts by the Mughals and Nizams attracted artisans from the region to Hyderabad. Such crafts include: Bidriware, a metalwork handicraft from neighbouring Karnataka, which was popularised during the 18th century and has since been granted a Geographical Indication (GI) tag under the auspices of the WTO act; and Zari and Zardozi, embroidery works on textile that involve making elaborate designs using gold, silver and other metal threads. Another example of a handicraft drawn to Hyderabad is Kalamkari, a hand-painted or block-printed cotton textile that comes from cities in Andhra Pradesh. This craft is distinguished in having both a Hindu style, known as Srikalahasti and entirely done by hand, and an Islamic style, known as Machilipatnam that uses both hand and block techniques. Examples of Hyderabad's arts and crafts are housed in various museums including the Salar Jung Museum (housing "one of the largest one-man-collections in the world"), the AP State Archaeology Museum, the Nizam Museum, the City Museum and the Birla Science Museum.

In which century did metalwork become popular in Hyderabad?

A: the 18th century


Problem: Ehrlich’s approach of systematically varying the chemical structure of synthetic compounds and measuring the effects of these changes on biological activity was pursued broadly by industrial scientists, including Bayer scientists Josef Klarer, Fritz Mietzsch, and Gerhard Domagk. This work, also based in the testing of compounds available from the German dye industry, led to the development of Prontosil, the first representative of the sulfonamide class of antibiotics. Compared to arsphenamine, the sulfonamides had a broader spectrum of activity and were far less toxic, rendering them useful for infections caused by pathogens such as streptococci. In 1939, Domagk received the Nobel Prize in Medicine for this discovery. Nonetheless, the dramatic decrease in deaths from infectious diseases that occurred prior to World War II was primarily the result of improved public health measures such as clean water and less crowded housing, and the impact of anti-infective drugs and vaccines was significant mainly after World War II.
Anti-infective drugs became more prominent after what war?

Answer: World War II

Question: The 5th Dalai Lama is known for unifying the Tibetan heartland under the control of the Gelug school of Tibetan Buddhism, after defeating the rival Kagyu and Jonang sects and the secular ruler, the Tsangpa prince, in a prolonged civil war. His efforts were successful in part because of aid from Güshi Khan, the Oirat leader of the Khoshut Khanate. With Güshi Khan as a largely uninvolved overlord, the 5th Dalai Lama and his intimates established a civil administration which is referred to by historians as the Lhasa state. This Tibetan regime or government is also referred to as the Ganden Phodrang.
Is there an answer to this question: Who is known for unifying the Tibetan heartland under the control of Kagyu?

Answer: unanswerable


QUES: The RIBA Guide to its Archive and History (1986) has a section on the "Statutory registration of architects" with a bibliography extending from a draft bill of 1887 to one of 1969. The Guide's section on "Education" records the setting up in 1904 of the RIBA Board of Architectural Education, and the system by which any school which applied for recognition, whose syllabus was approved by the Board and whose examinations were conducted by an approved external examiner, and whose standard of attainment was guaranteed by periodical inspections by a "Visiting Board" from the BAE, could be placed on the list of "recognized schools" and its successful students could qualify for exemption from RIBA examinations.
