Problem: Economy of Greece:

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.

Problem: Cotton remained a key crop in the Southern economy after emancipation and the end of the Civil War in 1865. Across the South, sharecropping evolved, in which landless black and white farmers worked land owned by others in return for a share of the profits. Some farmers rented the land and bore the production costs themselves. Until mechanical cotton pickers were developed, cotton farmers needed additional labor to hand-pick cotton. Picking cotton was a source of income for families across the South. Rural and small town school systems had split vacations so children could work in the fields during "cotton-picking."
Besides adults what segment of the southern US population was involved in the harvesting of cotton?

Context and question: Grape juice is obtained from crushing and blending grapes into a liquid. The juice is often sold in stores or fermented and made into wine, brandy, or vinegar. Grape juice that has been pasteurized, removing any naturally occurring yeast, will not ferment if kept sterile, and thus contains no alcohol. In the wine industry, grape juice that contains 723% of pulp, skins, stems and seeds is often referred to as "must". In North America, the most common grape juice is purple and made from Concord grapes, while white grape juice is commonly made from Niagara grapes, both of which are varieties of native American grapes, a different species from European wine grapes. In California, Sultana (known there as Thompson Seedless) grapes are sometimes diverted from the raisin or table market to produce white juice.
What juice is made when grapes are crushed and blended?
Answer: Grape juice

Question: In the United States, macabre-rock pioneer Alice Cooper achieved mainstream success with the top ten album School's Out (1972). In the following year blues rockers ZZ Top released their classic album Tres Hombres and Aerosmith produced their eponymous debut, as did Southern rockers Lynyrd Skynyrd and proto-punk outfit New York Dolls, demonstrating the diverse directions being pursued in the genre. Montrose, including the instrumental talent of Ronnie Montrose and vocals of Sammy Hagar and arguably the first all American hard rock band to challenge the British dominance of the genre, released their first album in 1973. Kiss built on the theatrics of Alice Cooper and the look of the New York Dolls to produce a unique band persona, achieving their commercial breakthrough with the double live album Alive! in 1975 and helping to take hard rock into the stadium rock era. In the mid-1970s Aerosmith achieved their commercial and artistic breakthrough with Toys in the Attic (1975), which reached number 11 in the American album chart, and Rocks (1976), which peaked at number three. Blue Oyster Cult, formed in the late 60s, picked up on some of the elements introduced by Black Sabbath with their breakthrough live gold album On Your Feet or on Your Knees (1975), followed by their first platinum album, Agents of Fortune (1976), containing the hit single "(Don't Fear) The Reaper", which reached number 12 on the Billboard charts. Journey released their eponymous debut in 1975 and the next year Boston released their highly successful debut album. In the same year, hard rock bands featuring women saw commercial success as Heart released Dreamboat Annie and The Runaways debuted with their self-titled album. While Heart had a more folk-oriented hard rock sound, the Runaways leaned more towards a mix of punk-influenced music and hard rock. The Amboy Dukes, having emerged from the Detroit garage rock scene and most famous for their Top 20 psychedelic hit "Journey to the Center of the Mind" (1968), were dissolved by their guitarist Ted Nugent, who embarked on a solo career that resulted in four successive multi-platinum albums between Ted Nugent (1975) and his best selling Double Live Gonzo (1978).
Is there an answer to this question: What band did Alice Cooper mimic?

Answer: unanswerable

Problem: CBC Television:

One of the most popular shows on CBC Television is the weekly Saturday night broadcast of NHL hockey games, Hockey Night in Canada. It has been televised by the network since 1952. During the NHL lockout and subsequent cancellation of the 2004-2005 hockey season, CBC instead aired various recent and classic movies, branded as Movie Night in Canada, on Saturday nights. Many cultural groups criticized this and suggested the CBC air games from minor hockey leagues; the CBC responded that most such broadcast rights were already held by other groups, but it did base each Movie Night broadcast from a different Canadian hockey venue. Other than hockey, CBC Sports properties include Toronto Raptors basketball, Toronto FC Soccer, and various other amateur and professional events.

The NHL refused the CBC access to hockey games during which season?
