Q: Question: Which country won the most gold medals at the Olympics during which the Munich massacre took place? Passage 1:On 15 August 2018, a British political controversy was initiated when the Daily Mail claimed that, prior to becoming Labour Party Leader, Jeremy Corbyn had been present at a 2014 wreath-laying at a cemetery which contained the graves of many Palestinian activists including Salah Khalaf and Atef Bseiso, both of whom were members of the Black September Organization and were behind the Munich massacre of Israeli athletes at the 1972 Summer Olympics. The wreath-laying took place during a commemorative ceremony for victims of the 1985 Israeli air strikes on the PLO headquarters in Tunis, Tunisia, which had been widely condemned at the time, including by the U.S. Government. Corbyn and the Conservative peer Baron Sheikh had been in Tunisia to attend the International Conference on Monitoring the Palestinian Political and Legal Situation in the Light of Israeli Aggression. The controversy was considered to be part of a wider series of issues relating to claims of antisemitism in the Labour party and Corbyn's personal position on the Middle East, which have escalated since Corbyn became a front-runner for Labour Party leader in August 2015.
Passage 2:In 1994, he was introduced to Erick Sermon of EPMD by his friend K-Solo. Sermon included Murray on his album No Pressure on the single "Hostile", with critics praising Murray's lyrical ability. His appearance on Hostile led to Murray being signed to Jive Records, and work began on his first album. Murray's debut single, The Most Beautifullest Thing in This World was released in 1994 and was a hit. The song was produced by Erick Sermon (who also provided background vocals) and peaked at number 50 on the Billboard 200 and number 3 on the Hot Rap Singles chart. Murray's debut album The Most Beautifullest Thing in This World, was named after the single and released in 1994 to widespread critical acclaim and commercial success, being certified Gold by the Recording Industry Association of America (RIAA) in August 1995. The album was also given 4 mics by The Source. Murray continued to enjoy a high media-profile by appearing on a Coca-Cola advertisement and as a featured guest on Mary J Blige's Be Happy, Total's Can't You See, R Kelly's Home Alone and LL Cool J's I Shot Ya.
Passage 3:Yet again, Town's season was dominated by their FA Cup run. They reached their fifth and so far last FA Cup Final. After a win over Hull City in Round 3, they scraped past Notts County and Liverpool, they beat York City in the quarter-final in a replay, before beating the favourites Sunderland at Ewood Park in the semi-final, meaning they would play Preston North End in the final, a repeat of the 1922 FA Cup Final, the only one of Town's previous final appearances that they won. The final at Wembley was the first since moving to the London stadium to go into extra time. The result would be the opposite to the 1922 final, with Town conceding a penalty to lose the match 10.
