Input: Consider Input: Question: Which seasons did Park win the Premier League with Manchester United? Passage:Park began his football career in his native South Korea and played for the Myongji University team before moving to Japan to play for Kyoto Purple Sanga. After Park's national team manager Guus Hiddink moved back to the Netherlands to manage PSV Eindhoven, Park followed him to the Dutch side a year later. After PSV reached the semi-finals of the 2004–05 UEFA Champions League, Park's talents were recognised by Manchester United manager Sir Alex Ferguson and he signed Park for a fee of around £4 million in July 2005. In his time at United, Park won the Premier League four times and also won the 2007–08 UEFA Champions League and the 2008 FIFA Club World Cup. He moved to Queens Park Rangers in July 2012 after suffering a reduction in his number of appearances for Manchester United the previous season. However, an injury-interrupted season with QPR, combined with the club's relegation, led to Park rejoining PSV on loan for the 2013–14 season.

Input: Consider Input: Question: In which year did Moshe Katsav deny Ami Popper's pardon request? Passage:Popper was charged and convicted of seven acts of murder in March 1991, and he was sentenced to seven terms of life imprisonment. While in prison Popper became devoutly religious, and in June 1993 he married a Canadian-Jewish woman from a family of Kach activists. Popper and his wife were granted conjugal visits, and they had three children. In 1999, his sentence was reduced to 40 years imprisonment by a presidential amnesty. Popper was initially imprisoned in Maasiyahu Prison, and was placed in the Torani cellblock, a special cellblock for religious inmates. Prisoners there pray three times a day and spend most of the day studying the Torah and other sacred texts. At one point, his cellmate was former minister Shlomo Benizri. After Benizri's release, Popper's influence in the Torani bloc grew, and he began harassing former President Moshe Katsav, serving a seven-year sentence for rape and other sexual offenses, as Katsav had refused Popper's request for a pardon while he was President. According to the Israel Prison Service, Popper had verbally abused Katsav and sent other inmates to harass him. In October 2012, Popper was transferred to the maximum-security Ayalon Prison. Right wing and Orthodox politicians in Israel have demanded his release along with other Israeli prisoners who were convicted of murder or other violence committed against Palestinians, in exchange for the release of Palestinian prisoners who committed murder or violence against Israelis.

Input: Consider Input: Question: What is the current largest existent glacier in the world? Passage:The old moraine landscape of Lower Saxony emerged in the course of four great glacial advances of the Scandinavian ice sheet 350,000 to 130,000 years ago – one during the Elster glaciation and three during the Saale glaciation. The glacier of the most recent, Weichselian glaciation only reached the northeastern edge of the present Elbe valley depression, so that the existing terminal moraines beyond that point there were only affected periglacially, for example in the shape of solifluction over the frozen ground, by meltwater erosion and sediments or through wind-blown deposits of sand. The last two Saale glaciation advances in particular, the Drenthe II and the Warthe stadia, unfolded the East Hanonerian Terminal Moraine. It is therefore geomorphologically younger than the geest in western and central Lower Saxony, but clearly older than the young moraine landscapes in Mecklenburg-Vorpommern and Ostholstein (= Baltic Uplands).
