Question: How many people are in the executive branch senate in the city where the creator of The Vegetative Sculpture I died?

<P0-S0> Vegetative Sculpture I is a public art work by artist Bernhard Heiliger located at the Lynden Sculpture Garden near Milwaukee, Wisconsin. <P0-S1> The sculpture has an abstract form; it is installed on the patio. <SEP> <P1-S0> The governments in Berlin, Bremen and Hamburg are designated by the term Senate. <P1-S1> In the three free states of Bavaria, Saxony, and Thuringia the government is referred to as the State Government (Staatsregierung), and in the other ten states the term Land Government (Landesregierung) is used. <P1-S2> Before January 1, 2000, Bavaria had a bicameral parliament, with a popularly elected Landtag, and a Senate made up of representatives of the state's major social and economic groups. <P1-S3> The Senate was abolished following a referendum in 1998. <P1-S4> The states of Berlin, Bremen, and Hamburg are governed slightly differently from the other states. <P1-S5> In each of those cities, the executive branch consists of a Senate of approximately eight, selected by the state's parliament; the senators carry out duties equivalent to those of the ministers in the larger states. <P1-S6> The equivalent of the Minister-President is the Senatspräsident (President of the Senate) in Bremen, the Erster Bürgermeister (First Mayor) in Hamburg, and the Regierender Bürgermeister (Governing Mayor) in Berlin. <P1-S7> The parliament for Berlin is called the Abgeordnetenhaus (House of Representatives), while Bremen and Hamburg both have a Bürgerschaft. <P1-S8> The parliaments in the remaining 13 states are referred to as Landtag (State Parliament). <SEP> <P2-S0> the secret bench of knowledge (formerly secret bench, lost paradise) is a sculpture created by canadian artist lea vivot and produced in multiple castings. <P2-S1> a prominent one is located at the entrance to the wellington street library and archives canada in ottawa, where it was initially placed in 1989 on the artist's own initiative. <P2-S2> one year later vivot removed it and it was replaced four years later by eugene boccia from toronto. <P2-S3> the sculpture was unveiled at about 9 am on the morning of may 1, 1994 in front of a crowd of about 3000 people. <P2-S4> the sculpture has many messages inscribed on it, written by school children, about the importance and pleasure of reading. <SEP> <P3-S0> after the september 2011 execution of troy davis, believed by many to be innocent, richard dieter, the director of the death penalty information center, said this case was a clear wake-up call to politicians across the united states. <P3-S1> he said: "they weren't expecting such passion from people in opposition to the death penalty. <P3-S2> there's a widely held perception that all americans are united in favor of executions, but this message came across loud and clear that many people are not happy with it." <P3-S3> brian evans of amnesty international, which led the campaign to spare davis's life, said that there was a groundswell in america of people "who are tired of a justice system that is inhumane and inflexible and allows executions where there is clear doubts about guilt". <P3-S4> he predicted the debate would now be conducted with renewed energy. <SEP> <P4-S0> Bernhard Heiliger (11 November 1915, Stettin - 25 October 1995, Berlin) was a German artist. <P4-S1> He was considered "West Germany's foremost sculptor", and his large public artworks are a prominent presence in many German cities, especially Berlin.
