Here is a question about this article: Hyderabad produces around 4,500 tonnes of solid waste daily, which is transported from collection units in Imlibun, Yousufguda and Lower Tank Bund to the dumpsite in Jawaharnagar. Disposal is managed by the Integrated Solid Waste Management project which was started by the GHMC in 2010. Rapid urbanisation and increased economic activity has also led to increased industrial waste, air, noise and water pollution, which is regulated by the Telangana Pollution Control Board (TPCB). The contribution of different sources to air pollution in 2006 was: 2050% from vehicles, 4070% from a combination of vehicle discharge and road dust, 1030% from industrial discharges and 310% from the burning of household rubbish. Deaths resulting from atmospheric particulate matter are estimated at 1,7003,000 each year. Ground water around Hyderabad, which has a hardness of up to 1000 ppm, around three times higher than is desirable, is the main source of drinking water but the increasing population and consequent increase in demand has led to a decline in not only ground water but also river and lake levels. This shortage is further exacerbated by inadequately treated effluent discharged from industrial treatment plants polluting the water sources of the city.
What is the answer to this question: What is the rating for the hardness of Hyderabad's water?
****
So... 1000 ppm

Here is a question about this article: In principle, the Planck constant could be determined by examining the spectrum of a black-body radiator or the kinetic energy of photoelectrons, and this is how its value was first calculated in the early twentieth century. In practice, these are no longer the most accurate methods. The CODATA value quoted here is based on three watt-balance measurements of KJ2RK and one inter-laboratory determination of the molar volume of silicon, but is mostly determined by a 2007 watt-balance measurement made at the U.S. National Institute of Standards and Technology (NIST). Five other measurements by three different methods were initially considered, but not included in the final refinement as they were too imprecise to affect the result.
What is the answer to this question: One other measure involved the molar volume of what element?
****
So... silicon

Here is a question about this article: In 2014, Turkey was ordered by the European Court of Human Rights to pay well over $100m in compensation to Cyprus for the invasion; Ankara announced that it would ignore the judgment. In 2014, a group of Cypriot refugees and a European parliamentarian, later joined by the Cypriot government, filed a complaint to the International Court of Justice, accusing Turkey of violating the Geneva Conventions by directly or indirectly transferring its civilian population into occupied territory. Over the preceding ten years, civilian transfer by Turkey had "reached new heights", in the words of one US ambassador.[f] Other violations of the Geneva and the Hague Conventionsboth ratified by Turkeyamount to what archaeologist Sophocles Hadjisavvas called "the organized destruction of Greek and Christian heritage in the north". These violations include looting of cultural treasures, deliberate destruction of churches, neglect of works of art, and altering the names of important historical sites, which was condemned by the International Council on Monuments and Sites. Hadjisavvas has asserted that these actions are motivated by a Turkish policy of erasing the Greek presence in Northern Cyprus within a framework of ethnic cleansing, as well as by greed and profit-seeking on the part of the individuals involved.
What is the answer to this question: What year was Turkey ordered to pay fines to Cyprus?
****
So...
2014
