Question: How many people attended the conference held near Berlin in January 1942? Passage:Following the invasion of Poland in 1939 most of the 3.5 million Polish Jews were rounded up and put into newly established ghettos by Nazi Germany. The system was intended to isolate the Jews from the outside world in order to facilitate their exploitation and abuse. The supply of food was inadequate, living conditions were cramped and unsanitary, and the Jews had no way to earn money. Malnutrition and lack of medicine led to soaring mortality rates. In 1941, the initial victories of the Wehrmacht over the Soviet Union inspired plans for the German colonisation of occupied Poland, including all territory within the new district of General Government. At the Wannsee Conference held near Berlin on 20 January 1942, new plans were outlined for the genocide of the Jews, known as the "Final Solution" to the Jewish Question. The extermination programme was codenamed Aktion Reinhard in German, to differentiate it from the Einsatzgruppen mass killing operations in territories conquered by Nazi Germany, in which half a million Jews had already been annihilated.

Question: How much did the position director of football for Newcastle United pay in 2013? Passage:On 16 June 2013, in a series of telephone interviews Kinnear claimed he had been appointed as director of football for Newcastle United. In a Talksport interview over the telephone on 17 June 2013, Kinnear claimed to have replaced someone called "Derek Lambesi" (sic) as the club's director of football, signed Dean Holdsworth at Wimbledon for 50,000 (actually 650,000), sold Robbie Earle (retired a year after Kinnear left), signed goalkeeper Tim Krul when he was previously manager (actually signed by Graeme Souness three years prior) and has been awarded the LMA Manager of the Year award three times despite only winning the award once, he also said he'd never been sacked in his life. Kinnear claimed to have signed John Hartson on a free when he in fact paid 7.5million for the striker. He also mispronounced the names of Yohan Cabaye, Hatem Ben Arfa, Shola Ameobi and others in the Talksport interview. The appointment, a three-year contract, was confirmed by Newcastle United on 18 June. The confusion around Kinnear's appointment to the role was criticised by former club chairman Freddy Shepherd in an interview with BBC Sport. Kinnear drew criticism when the 2013 summer transfer window closed with Kinnear failing to make a single permanent signing, lone recruit Loic Remy having been signed on loan from Queens Park Rangers. This criticism intensified at the end of the 2014 winter transfer window with Kinnear failing again to make a permanent signing, this after the 20million sale of midfielder Yohan Cabaye, with Luuk de Jong having been brought in on loan from Borussia Monchengladbach.
