Question: The creator of Unfolding died in a city with how many in the executive branch Senate?

<P0-S0> Bernhard Heiliger (11 November 1915, Stettin - 25 October 1995, Berlin) was a German artist. <P0-S1> He was considered "West Germany's foremost sculptor", and his large public artworks are a prominent presence in many German cities, especially Berlin. <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> 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. <P2-S1> he said: "they weren't expecting such passion from people in opposition to the death penalty. <P2-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." <P2-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". <P2-S4> he predicted the debate would now be conducted with renewed energy. <SEP> <P3-S0> possibly in part due to expedited federal habeas corpus procedures embodied in the antiterrorism and effective death penalty act of 1996, the pace of executions picked up, reaching a peak of 98 in 1999 and then they declined gradually to 28 in 2015. since the death penalty was reauthorized in 1976, 1,411 people have been executed, almost exclusively by the states, with most occurring after 1990. texas has accounted for over one-third of modern executions (although only two death sentences were imposed in texas during 2015, with the courts preferring to issue sentences of life without parole instead) and over four times as many as oklahoma, the state with the second-highest number. <P3-S1> california has the greatest number of prisoners on death row, has issued the highest number of death sentences but has held relatively few executions. <SEP> <P4-S0> Unfolding is a public art work by artist Bernhard Heiliger located at the Lynden Sculpture Garden near Milwaukee, Wisconsin. <P4-S1> The sculpture has an abstract form; it is installed on the patio.
