QUES: From late 2009 a handful of mainly southern eurozone member states started being unable to repay their national Euro-denominated government debt or to finance the bail-out of troubled financial sectors under their national supervision without the assistance of third parties. This so-called European debt crisis began after Greece's new elected government stopped masking its true indebtedness and budget deficit and openly communicated the imminent danger of a Greek sovereign default. Seeing a sovereign default in the eurozone as a shock, the general public, international and European institutions, and the financial community started to intensively reassess the economic situation and creditworthiness of eurozone states. Those eurozone states being assessed as not financially sustainable enough on their current path, faced waves of credit rating downgrades and rising borrowing costs including increasing interest rate spreads. As a consequence, the ability of these states to borrow new money to further finance their budget deficits or to refinance existing unsustainable debt levels was strongly reduced.
Which country was the first to be at risk for soverign default?

ANS: Greece

QUES: The U.S. Census Bureau reported that in 2000, 24.0% of San Diego residents were under 18, and 10.5% were 65 and over. As of 2011[update] the median age was 35.6; more than a quarter of residents were under age 20 and 11% were over age 65. Millennials (ages 18 through 34) constitute 27.1% of San Diego's population, the second-highest percentage in a major U.S. city. The San Diego County regional planning agency, SANDAG, provides tables and graphs breaking down the city population into 5-year age groups.
What percentage of San Diego's population was under the age of 18 in 2000?

ANS: 24.0%

QUES: On 6 September 2007, Belgian-based International Polar Foundation unveiled the Princess Elisabeth station, the world's first zero-emissions polar science station in Antarctica to research climate change. Costing $16.3 million, the prefabricated station, which is part of the International Polar Year, was shipped to the South Pole from Belgium by the end of 2008 to monitor the health of the polar regions. Belgian polar explorer Alain Hubert stated: "This base will be the first of its kind to produce zero emissions, making it a unique model of how energy should be used in the Antarctic." Johan Berte is the leader of the station design team and manager of the project which conducts research in climatology, glaciology and microbiology.
What type of research was Princess Elizabeth station built to study?

ANS: climate change

QUES: It was not unusual for electric recordings to be played back on acoustic phonographs. The Victor Orthophonic phonograph was a prime example where such playback was expected. In the Orthophonic, which benefited from telephone research, the mechanical pickup head was redesigned with lower resonance than the traditional mica type. Also, a folded horn with an exponential taper was constructed inside the cabinet to provide better impedance matching to the air. As a result, playback of an Orthophonic record sounded like it was coming from a radio.
What adjustments were made to the orthophonic to accommodate electric recordings?

ANS:
mechanical pickup head was redesigned with lower resonance than the traditional mica type
