Ex Input:
How common is the architecture style that flourished in Bohemia between 1910-1914?, Context: The original Cubist architecture is very rare. There is only one country in the world where Cubism was really applied to architecture – namely Bohemia (today Czech Republic) and especially its capital, Prague. Czech architects were the first and only ones in the world to ever design original Cubist buildings. Cubist architecture flourished for the most part between 1910–1914, but the Cubist or Cubism-influenced buildings were also built after the World War I. After the war, the architectural style called Rondo-Cubism was developed in Prague fusing the Cubist architecture with round shapes.

Ex Output:
very rare


Ex Input:
Factories in China often produce what type of gas in their emissions that acts as pollution?, Context: A dense wave of smog began in the Central and Eastern part of China on 2 December 2013 across a distance of around 1,200 kilometres (750 mi), including Tianjin, Hebei, Shandong, Jiangsu, Anhui, Shanghai and Zhejiang. A lack of cold air flow, combined with slow-moving air masses carrying industrial emissions, collected airborne pollutants to form a thick layer of smog over the region. The heavy smog heavily polluted central and southern Jiangsu Province, especially in and around Nanjing, with its AQI pollution Index at "severely polluted" for five straight days and "heavily polluted" for nine. On 3 December 2013, levels of PM2.5 particulate matter average over 943 micrograms per cubic metre, falling to over 338 micrograms per cubic metre on 4 December 2013. Between 3:00 pm, 3 December and 2:00pm, 4 December local time, several expressways from Nanjing to other Jiangsu cities were closed, stranding dozens of passenger buses in Zhongyangmen bus station. From 5 to 6 December, Nanjing issued a red alert for air pollution and closed down all kindergarten through middle schools. Children's Hospital outpatient services increased by 33 percent; general incidence of bronchitis, pneumonia, upper respiratory tract infections significantly increased. The smog dissipated 12 December. Officials blamed the dense pollution on lack of wind, automobile exhaust emissions under low air pressure, and coal-powered district heating system in North China region. Prevailing winds blew low-hanging air masses of factory emissions (mostly SO2) towards China's east coast.

Ex Output:
SO2


Ex Input:
Who is at the center of the Kumari Devi worship?, Context: Kumari Ghar is a palace in the center of the Kathmandu city, next to the Durbar square where a Royal Kumari selected from several Kumaris resides. Kumari, or Kumari Devi, is the tradition of worshipping young pre-pubescent girls as manifestations of the divine female energy or devi in South Asian countries. In Nepal the selection process is very rigorous. Kumari is believed to be the bodily incarnation of the goddess Taleju (the Nepali name for Durga) until she menstruates, after which it is believed that the goddess vacates her body. Serious illness or a major loss of blood from an injury are also causes for her to revert to common status. The current Royal Kumari, Matina Shakya, age four, was installed in October 2008 by the Maoist government that replaced the monarchy.

Ex Output:

Royal Kumari
