Article: Within months of beginning his tenure as the president of the university, Eisenhower was requested to advise U.S. Secretary of Defense James Forrestal on the unification of the armed services. About six months after his appointment, he became the informal Chairman of the Joint Chiefs of Staff in Washington. Two months later he fell ill, and he spent over a month in recovery at the Augusta National Golf Club. He returned to his post in New York in mid-May, and in July 1949 took a two-month vacation out-of-state. Because the American Assembly had begun to take shape, he traveled around the country during mid-to-late 1950, building financial support from Columbia Associates, an alumni association.

Question: What position did Eisenhower informally hold?
Ans: Chairman of the Joint Chiefs of Staff

Article: Burke claimed that Bolingbroke's arguments against revealed religion could apply to all social and civil institutions as well. Lord Chesterfield and Bishop Warburton (and others) initially thought that the work was genuinely by Bolingbroke rather than a satire. All the reviews of the work were positive, with critics especially appreciative of Burke's quality of writing. Some reviewers failed to notice the ironic nature of the book, which led to Burke stating in the preface to the second edition (1757) that it was a satire.

Question: When was the 2nd edition of Burke's book published?
Ans: 1757

Article: A dense wave of smog began in the Central and Eastern part of China on 2 December 2013 across a distance of around 1,200 kilometres (750 mi), including Tianjin, Hebei, Shandong, Jiangsu, Anhui, Shanghai and Zhejiang. A lack of cold air flow, combined with slow-moving air masses carrying industrial emissions, collected airborne pollutants to form a thick layer of smog over the region. The heavy smog heavily polluted central and southern Jiangsu Province, especially in and around Nanjing, with its AQI pollution Index at "severely polluted" for five straight days and "heavily polluted" for nine. On 3 December 2013, levels of PM2.5 particulate matter average over 943 micrograms per cubic metre, falling to over 338 micrograms per cubic metre on 4 December 2013. Between 3:00 pm, 3 December and 2:00pm, 4 December local time, several expressways from Nanjing to other Jiangsu cities were closed, stranding dozens of passenger buses in Zhongyangmen bus station. From 5 to 6 December, Nanjing issued a red alert for air pollution and closed down all kindergarten through middle schools. Children's Hospital outpatient services increased by 33 percent; general incidence of bronchitis, pneumonia, upper respiratory tract infections significantly increased. The smog dissipated 12 December. Officials blamed the dense pollution on lack of wind, automobile exhaust emissions under low air pressure, and coal-powered district heating system in North China region. Prevailing winds blew low-hanging air masses of factory emissions (mostly SO2) towards China's east coast.

Question: When did a thick wave of smog first appear in Central and Eastern China?
Ans: 2 December 2013

Article: Guests ascending to the 67th, 69th, and 70th level observation decks (dubbed "Top of the Rock") atop the GE Building at Rockefeller Center in New York City ride a high-speed glass-top elevator. When entering the cab, it appears to be any normal elevator ride. However, once the cab begins moving, the interior lights turn off and a special blue light above the cab turns on. This lights the entire shaft, so riders can see the moving cab through its glass ceiling as it rises and lowers through the shaft. Music plays and various animations are also displayed on the ceiling. The entire ride takes about 60 seconds.

Question: What do these floors serve as?
Ans:
observation decks
