Question: How long did the man that Ginjaar replaced as Minister for Science Policy serve in that position? Passage 1:His club was Eintracht Frankfurt with whom he won the 1959 German Championship, and in 1960 reached the finals of Champion's Cup against Real Madrid. The left-footed Don Alfredo was the head of the team. Pfaff was a true playmaker with exceptionally good ball control and great skills at free kicks. Pfaff probably would have accumulated more than seven caps if Fritz Walter had not played the same role for West Germany as Pfaff played for Eintracht Frankfurt. In 1954, Atletico Madrid offered him 180,000 D-Mark but his wife Edith was against a move to Spain. Possibly Pfaff's greatest game was the 61 against Rangers F.C. in the 195960 semifinal first leg of the European Champion Clubs' Cup, which was followed by a 63 win of Eintracht Frankfurt in Glasgow in the second leg. He ended his career in 1962 at the age of 36.
Passage 2:After the election of 1977 Ginjaar was appointed as Minister of Health and Environment in the Cabinet Van Agt-Wiegel, taking office on 19 December 1977.

In December 1980 Ginjaar announced that he wouldn't stand for the election of 1981 but wanted to run for the Senate. Ginjaar was elected as a Member of the Senate after the Senate election of 1981, taking office on 25 August 1981 serving as a frontbencher chairing the and the and spokesperson for the Environment, Higher Education and Agriculture. The Cabinet Van AgtWiegel was replaced by the Cabinet Van Agt II following the cabinet formation of 1981 on 11 September 1981. Ginjaar also served as Chairmen of the People's Party for Freedom and Democracy from 29 November 1986 until 4 October 1991. Ginjaar served as a distinguished professor of Medical ethics at the Utrecht University from 1 September 1982 until 1 January 1986 and also served as Chairman of the Education board of the Utrecht University from 10 September 1982 until 1 January 1986 and a distinguished professor of Climatology and Medical research at the State University of Limburg from 1 March 1990 until 1 September 1994. Ginjaar was selected as Parliamentary leader of the People's Party for Freedom and Democracy in the Senate following the election of Frits Korthals Altes as President of the Senate, serving from 11 March 1997 until 14 September 1999. In November 2002 Ginjaar announced his retirement from national politics and that he wouldn't stand for the Senate election of 2003 and continued to serve until the end of the parliamentary term on 10 June 2003.
Passage 3:The Charlemagne Prize (; full name originally Internationaler Karlspreis der Stadt Aachen, International Charlemagne Prize of the City of Aachen, since 1988 Internationaler Karlspreis zu Aachen, International Charlemagne Prize of Aachen) is a prize awarded for work done in the service of European unification. It has been awarded annually since 1950 by the German city of Aachen. It commemorates Charlemagne, ruler of the Frankish Empire and founder of what became the Holy Roman Empire, who resided and is buried in Aachen. Traditionally the award is given to the recipient on Ascension Day in a ceremony in the town hall of Aachen. In April 2008, the organisers of the Charlemagne Prize and the European Parliament jointly created a new European Charlemagne Youth Prize, which recognises contributions by young people towards the process of European integration. Patrons of the foundation are King Philippe of Belgium, King Felipe VI of Spain, and Henri, the Grand Duke of Luxembourg.
