Question: How many total album sales were made between the 1978 Who album that Bundrick was invited to play on and the 1981 album that he was featured on? Passage:Bundrick first worked with Pete Townshend in 1977 when he performed on Rough Mix, Townshend's solo collaboration with Ronnie Lane, former bass player for Small Faces and Faces.

Question: How old was Georges Braque when he collaborated with Guardigli to create the famous long fish tank of the Fondation Maeght Passage:Guardigli was born in Ravenna. At 18 he enrolled in and attended the School of Fine Arts of Ravenna. During World War II he was drafted and served from 1943 until 1946 in the Regia Marina (Italian Royal Navy) at La Spezia). After the war he returned to the School of Fine Arts, receiving his diploma in 1948. He enrolled in the School of Painting and Mosaics, also in Ravenna, graduating in 1951. From 1951 to 1955 he worked with the Gruppo mosaicisti of Ravenna and restored many mosaics. Also in 1951, at the end of November, he arrived in Paris to teach at the Ecole d'Art Italien (School of Italian Art) as an assistant to the painter Gino Severini, founder and director of the school. Together with another mosaicist, his fellow Ravennan Lino Melano, he executed mosaic works for artists including Fernand Léger, Georges Braque, Marc Chagall, Jean Bazaine, and Raoul Ubac. He collaborated also on the mosaic for the façade of the Musée national Fernand Léger in Biot (Alpes-Maritimes). In 1960 he executed, at the Colombe d'Or of Saint-Paul-de-Vence, a mosaic by the painter Georges Braque. From 1961 he had a studio in the artists' residence La Ruche at 2, passage de Dantzing in Paris, the place described by Lorenzo Viani in the book Parigi 1925 (Paris 1925), published by Fratelli Treves. In 1962, in another collaboration with Braque, he created the famous long fish tank of the Fondation Maeght in St Paul de Vence. His collaborations with many illustrious artists continued; the last was Jean-Michel Folon. Many of his personal works in painting and mosaics are in prominent private and public collections. The latter portion of his life was spent in an old people's rest home in Paris, where he died in 2008.

Question: Did the current Global recession start before or after the European debt crisis? Passage:World Bank classifies Latin America in the lower middle and upper middle income range. An estimated 181 million individuals (33.2 percent of the population) live in poverty and seventy-one million of these (12.9 percent) in indigence. Between 2002 and 2008, forty-one million people were able to sustain enough progress to no longer be characterized as poverty but with the current Global recession, this number has decreased by nine million. Ten of the 15 countries with the highest levels of inequality are in the region. Women, indigenous populations and those of African descent are most affected. Females in the region take a greater part in the informal economy and have double the workload than males but are paid less for their efforts. When compared to those of European descent, twice as many members of indigenous and African descended populations, on average, live on US$1 per day. Latin America still faces corrupt political, judicial, and security institutions protective of the interests of the wealthy. The second edition of the Global Burden of Armed Violence report by the Secretariat of the Geneva Declaration on Armed Violence and Development, released in October 2011, characterized El Salvador as being the "most violent country in the world" during 2004–9, with an average annual violent death rate of over 60 per 100,000 people during that period, just ahead of Iraq. During the first week of November (2011), Manuel Melgar (the justice and public security minister of El Salvador) resigned from his post. The region overall is second to South Africa in terms of levels of crime and violence. Educational practices are also being questioned across the region. Chile has been experiencing five months of protests against the government's attempt to maintain the higher education's private sector model. Students and teachers in opposition hope to revert to a state funded model, under an "Education for All" slogan in fear of emerging from universities with debts and loans. These street demonstrations, now catching congress' attention, are a threat to Chiles' 2012 budget. Without the proposed spending, potential education, health, training and anti-poverty programs will cease. In Latin America, risks of inflation and excessive currency appreciation are a concern to the region's long-term growth prospects and present instability in the financial sector. Current events such as the European debt crisis, the slow recovery in the US, natural and nuclear disasters in Japan and the implications from the political turmoil in the Middle East stall progress within the region and foreshadow more difficult economic conditions.
