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 growth rate of Greece in 2013?

ANS: −3.2%

QUES: Renewable energy technologies are getting cheaper, through technological change and through the benefits of mass production and market competition. A 2011 IEA report said: "A portfolio of renewable energy technologies is becoming cost-competitive in an increasingly broad range of circumstances, in some cases providing investment opportunities without the need for specific economic support," and added that "cost reductions in critical technologies, such as wind and solar, are set to continue." As of 2011[update], there have been substantial reductions in the cost of solar and wind technologies:
What is getting cheaper as a result of technilogical change?

ANS: Renewable energy technologies

QUES: South West England has a favoured location when the Azores High pressure area extends north-eastwards towards the UK, particularly in summer. Coastal areas have average annual sunshine totals over 1,600 hours.
How many hours of sunshine does the South West England region get each year?

ANS: over 1,600

QUES: The capacitance of certain capacitors decreases as the component ages. In ceramic capacitors, this is caused by degradation of the dielectric. The type of dielectric, ambient operating and storage temperatures are the most significant aging factors, while the operating voltage has a smaller effect. The aging process may be reversed by heating the component above the Curie point. Aging is fastest near the beginning of life of the component, and the device stabilizes over time. Electrolytic capacitors age as the electrolyte evaporates. In contrast with ceramic capacitors, this occurs towards the end of life of the component.
 What is one of the least important aging factors in capacitors?

ANS:
