QUES: World War II (1939-1945) devastated the country's economy, but the high levels of economic growth that followed from 1950 to 1980 have been called the Greek economic miracle. From 2000 Greece saw high levels of GDP growth above the Eurozone average, peaking at 5.8% in 2003 and 5.7% in 2006. The subsequent Great Recession and Greek government-debt crisis, a central focus of the wider European debt crisis, plunged the economy into a sharp downturn, with real GDP growth rates of 0.3% in 2008, 4.3% in 2009, 5.5% in 2010, 9.1% in 2011, 7.3% in 2012 and 3.2% in 2013. In 2011, the country's public debt reached 356 billion (172% of nominal GDP). After negotiating the biggest debt restructuring in history with the private sector, Greece reduced its sovereign debt burden to 280 billion (137% of GDP) in the first quarter of 2012. Greece achieved a real GDP growth rate of 0.7% in 2014 after 6 years of economic decline, but fell back into recession in 2015.

What was the GDP reduction rate of Greece in 2011?
What is the answer?
ANS: unanswerable
QUES: Two days later, it was announced that Luis Enrique would return to Barcelona as head coach, after he agreed to a two-year deal. He was recommended by sporting director Andoni Zubizarreta, his former national teammate. Following Enrique's arrival, Barcelona broke their transfer record when they paid Liverpool F.C. between 81 to 94 million for striker Luis Suarez, who was serving a four-month ban from all football-related activity imposed by the FIFA Disciplinary Committee after biting Italian defender Giorgio Chiellini during his appearance for Uruguay in a World Cup group stage match.

How much did Barcelona pay for Luis Saurez?
What is the answer?
ANS: between 81 to 94 million
QUES: Hydrogen production technologies been a significant area of solar chemical research since the 1970s. Aside from electrolysis driven by photovoltaic or photochemical cells, several thermochemical processes have also been explored. One such route uses concentrators to split water into oxygen and hydrogen at high temperatures (2,3002,600 C or 4,2004,700 F). Another approach uses the heat from solar concentrators to drive the steam reformation of natural gas thereby increasing the overall hydrogen yield compared to conventional reforming methods. Thermochemical cycles characterized by the decomposition and regeneration of reactants present another avenue for hydrogen production. The Solzinc process under development at the Weizmann Institute uses a 1 MW solar furnace to decompose zinc oxide (ZnO) at temperatures above 1,200 C (2,200 F). This initial reaction produces pure zinc, which can subsequently be reacted with water to produce hydrogen.

What is one of the thermochemical processes that has been explored besides electrolysis?
What is the answer?
ANS:
uses concentrators to split water into oxygen and hydrogen at high temperatures
