Problem: Egypt has a developed energy market based on coal, oil, natural gas, and hydro power. Substantial coal deposits in the northeast Sinai are mined at the rate of about 600,000 tonnes (590,000 long tons; 660,000 short tons) per year. Oil and gas are produced in the western desert regions, the Gulf of Suez, and the Nile Delta. Egypt has huge reserves of gas, estimated at 2,180 cubic kilometres (520 cu mi), and LNG up to 2012 exported to many countries. In 2013, the Egyptian General Petroleum Co (EGPC) said the country will cut exports of natural gas and tell major industries to slow output this summer to avoid an energy crisis and stave off political unrest, Reuters has reported. Egypt is counting on top liquid natural gas (LNG) exporter Qatar to obtain additional gas volumes in summer, while encouraging factories to plan their annual maintenance for those months of peak demand, said EGPC chairman, Tarek El Barkatawy. Egypt produces its own energy, but has been a net oil importer since 2008 and is rapidly becoming a net importer of natural gas.
What efforts were made in 2013 to maintain sustainability?

Answer: cut exports of natural gas and tell major industries to slow output this summer to avoid an energy crisis

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
At the same time the Empire style in France was a more grandiose wave of neoclassicism in architecture and the decorative arts. Mainly based on Imperial Roman styles, it originated in, and took its name from, the rule of Napoleon I in the First French Empire, where it was intended to idealize Napoleon's leadership and the French state. The style corresponds to the more bourgeois Biedermeier style in the German-speaking lands, Federal style in the United States, the Regency style in Britain, and the Napoleonstil in Sweden. According to the art historian Hugh Honour "so far from being, as is sometimes supposed, the culmination of the Neo-classical movement, the Empire marks its rapid decline and transformation back once more into a mere antique revival, drained of all the high-minded ideas and force of conviction that had inspired its masterpieces".
What did Hugh Honour see as the culmination of the neoclassical movement?
A: unanswerable

Context and question: On February 7, 1987, dozens of political prisoners were freed in the first group release since Khrushchev's "thaw" in the mid-1950s. On May 6, 1987, Pamyat, a Russian nationalist group, held an unsanctioned demonstration in Moscow. The authorities did not break up the demonstration and even kept traffic out of the demonstrators' way while they marched to an impromptu meeting with Boris Yeltsin, head of the Moscow Communist Party and at the time one of Gorbachev's closest allies. On July 25, 1987, 300 Crimean Tatars staged a noisy demonstration near the Kremlin Wall for several hours, calling for the right to return to their homeland, from which they were deported in 1944; police and soldiers merely looked on.
Who released the prisoners in the 1950s?
Answer: Khrushchev's

Question: In Sri Lanka, the Supreme Court of Sri Lanka was created in 1972 after the adoption of a new Constitution. The Supreme Court is the highest and final superior court of record and is empowered to exercise its powers, subject to the provisions of the Constitution. The court rulings take precedence over all lower Courts. The Sri Lanka judicial system is complex blend of both common-law and civil-law. In some cases such as capital punishment, the decision may be passed on to the President of the Republic for clemency petitions. However, when there is 2/3 majority in the parliament in favour of president (as with present), the supreme court and its judges' powers become nullified as they could be fired from their positions according to the Constitution, if the president wants. Therefore, in such situations, Civil law empowerment vanishes.
Is there an answer to this question: What majority is necessary in the Sri Lankan Parliament to dismiss a president and the Court?

Answer: 2/3

Problem: Orthodox Judaism:

Jewish historians also note that certain customs of today's Orthodox are not continuations of past practice, but instead represent innovations that would have been unknown to prior generations. For example, the now-widespread haredi tradition of cutting a boy's hair for the first time on his third birthday (upshirin or upsheerin, Yiddish for "haircut") "originated as an Arab custom that parents cut a newborn boy's hair and burned it in a fire as a sacrifice," and "Jews in Palestine learned this custom from Arabs and adapted it to a special Jewish context." The Ashkenazi prohibition against eating kitniyot (grains and legumes such as rice, corn, beans, and peanuts) during Passover was explicitly rejected in the Talmud, has no known precedent before the 12th century and represented a minority position for hundreds of years thereafter, but nonetheless has remained a mandatory prohibition among Ashkenazi Orthodox Jews due to their historic adherence to the ReMA's rulings in the Shulchan Aruch.

What do historians note are continuations of past practices?
