QUES: Eton has a long list of distinguished former pupils. David Cameron is the 19th British prime minister to have attended the school, and has recommended that Eton set up a school in the state sector to help drive up standards. Eton now co-sponsors a state sixth-form college in Newham, a deprived area of East London, called the London Academy of Excellence, opened in 2012, which is free of charge and aims to get all its students into higher education. In September 2014, Eton opened, and became the sole educational sponsor for, a new purpose-built co-educational state boarding and day school for around 500 pupils, Holyport College, in Maidenhead in Berkshire, with construction costing around £15 million, in which a fifth of places for day pupils will be set aside for children from poor homes, 21 boarding places will go to youngsters on the verge of being taken into care, and a further 28 boarders will be funded or part-funded through bursaries.
Where is Eton located?

ANS: unanswerable

QUES: Meanwhile, Andreas Papandreou founded the Panhellenic Socialist Movement (PASOK) in response to Karamanlis's conservative New Democracy party, with the two political formations alternating in government ever since. Greece rejoined NATO in 1980. Greece became the tenth member of the European Communities (subsequently subsumed by the European Union) on 1 January 1981, ushering in a period of sustained growth. Widespread investments in industrial enterprises and heavy infrastructure, as well as funds from the European Union and growing revenues from tourism, shipping and a fast-growing service sector raised the country's standard of living to unprecedented levels. Traditionally strained relations with neighbouring Turkey improved when successive earthquakes hit both nations in 1999, leading to the lifting of the Greek veto against Turkey's bid for EU membership.
In what year did Greece rejoin NATO?

ANS: 1980

QUES: According to the International Energy Agency, cellulosic ethanol biorefineries could allow biofuels to play a much bigger role in the future than organizations such as the IEA previously thought. Cellulosic ethanol can be made from plant matter composed primarily of inedible cellulose fibers that form the stems and branches of most plants. Crop residues (such as corn stalks, wheat straw and rice straw), wood waste, and municipal solid waste are potential sources of cellulosic biomass. Dedicated energy crops, such as switchgrass, are also promising cellulose sources that can be sustainably produced in many regions.
What is a promising cellulose source that can be sustainably produced in many regions?

ANS: Dedicated energy crops

QUES: At Princeton, the physicist Robert R. Wilson encouraged Feynman to participate in the Manhattan Project—the wartime U.S. Army project at Los Alamos developing the atomic bomb. Feynman said he was persuaded to join this effort to build it before Nazi Germany developed their own bomb. He was assigned to Hans Bethe's theoretical division and impressed Bethe enough to be made a group leader. He and Bethe developed the Bethe–Feynman formula for calculating the yield of a fission bomb, which built upon previous work by Robert Serber.
What was the purpose of the Bethe-Feynman formula?

ANS:
calculating the yield of a fission bomb
