Problem: YouTube:

During the same court battle, Viacom won a court ruling requiring YouTube to hand over 12 terabytes of data detailing the viewing habits of every user who has watched videos on the site. The decision was criticized by the Electronic Frontier Foundation, which called the court ruling "a setback to privacy rights". In June 2010, Viacom's lawsuit against Google was rejected in a summary judgment, with U.S. federal Judge Louis L. Stanton stating that Google was protected by provisions of the Digital Millennium Copyright Act. Viacom announced its intention to appeal the ruling.

Which organization spoke against the courts ruling?

A: Electronic Frontier Foundation

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
After a trend of declining population density since World War II, the city has seen increased density in the inner and western suburbs, aided in part by Victorian Government planning, such as Postcode 3000 and Melbourne 2030 which have aimed to curtail urban sprawl. According to the Australian Bureau of Statistics as of June 2013, inner city Melbourne had the highest population density with 12,400 people per km2. Surrounding inner city suburbs experienced an increase in population density between 2012 and 2013; Carlton (9,000 people per km2) and Fitzroy (7,900).
How many people did Carlton have per km2 between 2012 and 2013?
A: 9,000


Context and question: Think-tanks such as the World Pensions Council have also argued that European legislators have pushed somewhat dogmatically for the adoption of the Basel II recommendations, adopted in 2005, transposed in European Union law through the Capital Requirements Directive (CRD), effective since 2008. In essence, they forced European banks, and, more importantly, the European Central Bank itself e.g. when gauging the solvency of financial institutions, to rely more than ever on standardised assessments of credit risk marketed by two non-European private agencies: Moody's and S&P.
Which agencies have became the authority on assessing the risk of financial institutions?
Answer: Moody's and S&P


Question: The basic ingredients of beer are water; a starch source, such as malted barley, able to be saccharified (converted to sugars) then fermented (converted into ethanol and carbon dioxide); a brewer's yeast to produce the fermentation; and a flavouring such as hops. A mixture of starch sources may be used, with a secondary starch source, such as maize (corn), rice or sugar, often being termed an adjunct, especially when used as a lower-cost substitute for malted barley. Less widely used starch sources include millet, sorghum and cassava root in Africa, and potato in Brazil, and agave in Mexico, among others. The amount of each starch source in a beer recipe is collectively called the grain bill.
Is there an answer to this question: What are several widely used starch sources that are used and found in various countries?

Answer: unanswerable


Question: The first railways in Thuringia had been built in the 1840s and the network of main lines was finished around 1880. By 1920, many branch lines had been built, giving Thuringia one of the densest rail networks in the world before World War II with about 2,500 km of track. Between 1950 and 2000 most of the branch lines were abandoned, reducing Thuringia's network by half compared to 1940. On the other hand, most of the main lines were refurbished after 1990, resulting in improved speed of travel. The most important railway lines at present are the Thuringian Railway, connecting Halle and Leipzig via Weimar, Erfurt, Gotha and Eisenach with Frankfurt and Kassel and the Saal Railway from Halle/Leipzig via Jena and Saalfeld to Nuremberg. The former has an hourly ICE/IC service from Dresden to Frankfurt while the latter is served hourly by ICE trains from Berlin to Munich. In 2017, a new high speed line will be opened, diverting long-distance services from these mid-19th century lines. Both ICE routes will then use the Erfurt–Leipzig/Halle high-speed railway, and the Berlin-Munich route will continue via the Nuremberg–Erfurt high-speed railway. Only the segment west of Erfurt of the Frankfurt-Dresden line will continue to be used by ICE trains after 2017, with an increased line speed of 200 km/h (currently 160 km/h). Erfurt's central station, which was completely rebuilt for this purpose in the 2000s (decade), will be the new connection between both ICE lines. The most important regional railway lines in Thuringia are the Neudietendorf–Ritschenhausen railway from Erfurt to Würzburg and Meiningen, the Weimar–Gera railway from Erfurt to Chemnitz, the Sangerhausen–Erfurt railway from Erfurt to Magdeburg, the Gotha–Leinefelde railway from Erfurt to Göttingen, the Halle–Kassel railway from Halle via Nordhausen to Kassel and the Leipzig–Hof railway from Leipzig via Altenburg to Zwickau and Hof. Most regional and local lines have hourly service, but some run only every other hour.
Is there an answer to this question: When were most of the branch lines of the railway abandoned? 

Answer:
Between 1950 and 2000
