Article: Besides emptiness, Mahayana schools often place emphasis on the notions of perfected spiritual insight (prajnaparamita) and Buddha-nature (tathagatagarbha). There are conflicting interpretations of the tathagatagarbha in Mahayana thought. The idea may be traced to Abhidharma, and ultimately to statements of the Buddha in the Nikayas. In Tibetan Buddhism, according to the Sakya school, tathagatagarbha is the inseparability of the clarity and emptiness of one's mind. In Nyingma, tathagatagarbha also generally refers to inseparability of the clarity and emptiness of one's mind. According to the Gelug school, it is the potential for sentient beings to awaken since they are empty (i.e. dependently originated). According to the Jonang school, it refers to the innate qualities of the mind that expresses themselves as omniscience etc. when adventitious obscurations are removed. The "Tathagatagarbha Sutras" are a collection of Mahayana sutras that present a unique model of Buddha-nature. Even though this collection was generally ignored in India, East Asian Buddhism provides some significance to these texts.

Question: what does prajnaparamita mean?
Ans: perfected spiritual insight

Article: Hayek was one of the leading academic critics of collectivism in the 20th century. Hayek argued that all forms of collectivism (even those theoretically based on voluntary co-operation) could only be maintained by a central authority of some kind. In Hayek's view, the central role of the state should be to maintain the rule of law, with as little arbitrary intervention as possible. In his popular book, The Road to Serfdom (1944) and in subsequent academic works, Hayek argued that socialism required central economic planning and that such planning in turn leads towards totalitarianism.

Question: How did Hayek believe collectivism could be maintained?
Ans: a central authority

Article: Melbourne has the largest tram network in the world which had its origins in the city's 1880s land boom. In 20132014, 176.9 million passenger trips were made by tram. Melbourne's is Australia's only tram network to comprise more than a single line and consists of 250 km (155.3 mi) of track, 487 trams, 25 routes, and 1,763 tram stops.

Article: By the end of 2011, total renewable power capacity worldwide exceeded 1,360 GW, up 8%. Renewables producing electricity accounted for almost half of the 208 GW of capacity added globally during 2011. Wind and solar photovoltaics (PV) accounted for almost 40% and 30% . Based on REN21's 2014 report, renewables contributed 19 percent to our energy consumption and 22 percent to our electricity generation in 2012 and 2013, respectively. This energy consumption is divided as 9% coming from traditional biomass, 4.2% as heat energy (non-biomass), 3.8% hydro electricity and 2% electricity from wind, solar, geothermal, and biomass.

Question: Renewables contributed what percentage to our energy consumption?
Ans:
19 percent
