The answer to the question: What system pairs the eight songs off against each other? is inside the article: Prior to the introduction of the current format of semifinals (deltavlingar) in 2002, the competition was usually a single live show. Under the current system, four semifinals are broadcast at 20:00 CET on consecutive Saturday nights. The semi-finals begin in early February, and seven songs compete in each show. Unlike in the final, no juries are used; televoting decides the results. The songs are performed live with telephone lines open for the first round of voting; two songs with the fewest votes do not qualify to the second round. The top five battle for a place in the final and Andra chansen round the 1st and 2nd placed songs qualifying to the final, and the 3rd and 4th placed songs progressing to Andra chansen. Both finalists reprise their entries at the end of the broadcast. The organisation of a semi-final system for Melodifestivalen popularised televised heats at national Eurovision selections. A similar system was adopted by the Eurovision itself in 2004. The Second Chance round (Andra chansen) is the fifth heat in which the remaining four entries to the final are chosen. The third- and fourth-placed songs from each semi-final (eight songs in total) compete in the event. The first Second Chance round in 2002 had a panel of former winners decide the two finalists. Between 2003 and 2006, the semi-final performances were re-broadcast, and a round of voting narrowed the songs to three or four. Another round then determined the two finalists. The programme was broadcast on the Sunday afternoon after the fourth semi-final. It was held in a smaller venue than those that would have hosted the semi-finalssuch as Berns Salonger in Stockholm, which hosted the Second Chance round in 2005. In 2007, the Second Chance round became a full semi-final, taking place in a venue comparable in size to those hosting the others. The expanded Second Chance takes place on a Saturday night, adding an extra week to the event's timetable. The format of voting also changed with the introduction of a knock-out system.

The answer to the question: What is the first name of the person who performed the tendon-repair operation in the early 90s?? is inside the article: In 2007 Yehuda David, a physician at Tel Hashomer hospital near Tel Aviv, told Israel's Channel 10 that he had treated Jamal Al-Durrah in 1994 for knife and axe wounds to his arms and legs, injuries sustained during a gang attack. David maintained that the scars Jamal had presented as bullet wounds were in fact scars from a tendon-repair operation David had performed in the early 90s. When David repeated his allegations in an interview with a "Daniel Vavinsky," published in 2008 in Actualite Juive in Paris, Jamal filed a complaint with the Tribunal de grande instance de Paris for defamation and breach of doctor-patient confidentiality.The court established that "Daniel Vavinsky" was a pseudonym for Clement Weill-Raynal, a deputy editor at France 3. In 2011 it ruled that David and Actualite Juive had defamed Jamal. David, Weill-Raynal and Serge Benattar, the managing editor of Actualite Juive, were fined 5,000 each, and Actualite Juive was ordered to print a retraction. The Israeli government said it would fund David's appeal. The appeal was upheld in 2012; David was acquitted of defamation and breach of confidentiality. Benjamin Netanyahu, Israeli's prime minister, telephoned David to congratulate him. Jamal Al-Durrah said he would appeal the court's decision.In 2012 Rafi Walden, deputy director of the Tel Hashomer hospital and board member of Physicians for Human Rights, wrote in Haaretz that he had examined Jamal's 50-page medical file, and that the injuries from the 2000 shooting were "completely different wounds" from the 1994 injuries. Walden listed "a gunshot wound in the right wrist, a shattered forearm bone, multiple fragment wounds in a palm, gunshot wounds in the right thigh, a fractured pelvis, an exit wound in the buttocks, a tear in the main nerve of the right thigh, tears in the main groin arteries and veins, and two gunshot wounds in the left lower leg.", can you guess it ?
