question:
Passage: The building was sold in 1549 by Buonaccorso Pitti, a descendant of Luca Pitti, to Eleonora di Toledo.  Raised at the luxurious court of Naples, Eleonora was the wife of Cosimo I de' Medici of Tuscany, later the Grand Duke.  On moving into the palace, Cosimo had Vasari enlarge the structure to fit his tastes; the palace was more than doubled by the addition of a new block along the rear.  Vasari also built the Vasari Corridor, an above-ground walkway from Cosimo's old palace and the seat of government, the Palazzo Vecchio, through the Uffizi, above the Ponte Vecchio to the Palazzo Pitti. This enabled the Grand Duke and his family to move easily and safely from their official residence to the Palazzo Pitti. Initially the Palazzo Pitti was used mostly for lodging official guests and for occasional functions of the court, while the Medicis' principal residence remained the Palazzo Vecchio. It was not until the reign of Eleonora's son Francesco I and his wife Johanna of Austria that the palazzo was occupied on a permanent basis and became home to the Medicis' art collection.Land on the Boboli hill at the rear of the palazzo was acquired in order to create a large formal park and gardens, today known as the Boboli Gardens. The landscape architect employed for this was the Medici court artist Niccolò Tribolo, who died the following year; he was quickly succeeded by Bartolommeo Ammanati. The original design of the gardens centred on an amphitheatre, behind the corps de logis of the palazzo. The first play recorded as performed there was Andria by Terence in 1476. It was followed by many classically inspired plays of Florentine playwrights such as Giovan Battista Cini. Performed for the amusement of the cultivated Medici court, they featured elaborate sets designed by the court architect Baldassarre Lanci. 
Question: What is the first name of the Grand Duke whose family was enabled to move easily and safely from their official residence?
answer:
Cosimo.


question:
Passage: After the recording sessions were completed, Nirvana sent unmastered tapes of the album to several individuals, including the president of DGC's parent company Geffen Records Ed Rosenblatt and the group's management company Gold Mountain.  When asked about the feedback he received, Cobain told Michael Azerrad, "The grown-ups don't like it."  He said he was told his songwriting was "not up to par", the sound was "unlistenable", and that there was uncertainty that mainstream radio would welcome the sound of Albini's production.  There were few people at Geffen or Gold Mountain who wanted the band to record with Albini to begin with, and Cobain felt he was receiving an unstated message to scrap the sessions and start all over again.  Cobain was upset and said to Azerrad, "I should just re-record this record and do the same thing we did last year because we sold out last year—there's no reason to try and redeem ourselves as artists at this point.  I can't help myself—I'm just putting out a record I would like to listen to at home."  However, a number of the group's friends liked the album, and by April 1993, Nirvana was intent on releasing In Utero as it was.  According to Cobain, "Of course, they want another Nevermind, but I'd rather die than do that.  This is exactly the kind of record I would buy as a fan, that I would enjoy owning."The band members began to have doubts about the record's sound.  During this time, Cobain admitted, "The first time I played it at home, I knew there was something wrong.  The whole first week I wasn't really interested in listening to it at all, and that usually doesn't happen.  I got no emotion from it, I was just numb."  The group concluded that the bass and lyrics were inaudible and approached Albini to remix the album.  The producer declined; as he recalled, "[Cobain] wanted to make a record that he could slam down on the table and say, 'Listen, I know this is good, and I know your concerns about it are meaningless, so go with it.'  And I don't think he felt he had that yet ...  My problem was that I feared a slippery slope."  The band attempted to fix its concerns with the record during the mastering process with Bob Ludwig at his studio in Portland, Maine.  Novoselic was pleased with the results, but Cobain still did not feel the sound was perfect. 
Question: What was the name of the album Nirvana was intent on releasing as it was?
answer:
In Utero.


question:
Passage: As the purge claimed the lives of so many prominent Germans, it could hardly be kept secret. At first, its architects seemed split on how to handle the event. Göring instructed police stations to burn "all documents concerning the action of the past two days." Meanwhile, Goebbels tried to prevent newspapers from publishing lists of the dead, but at the same time used a July 2 radio address to describe how Hitler had narrowly prevented Röhm and Schleicher from overthrowing the government and throwing the country into turmoil. Then, on July 13, 1934, Hitler justified the purge in a nationally broadcast speech to the Reichstag:
If anyone reproaches me and asks why I did not resort to the regular courts of justice, then all I can say is this. In this hour I was responsible for the fate of the German people, and thereby I became the supreme judge of the German people. I gave the order to shoot the ringleaders in this treason, and I further gave the order to cauterise down to the raw flesh the ulcers of this poisoning of the wells in our domestic life. Let the nation know that its existence—which depends on its internal order and security—cannot be threatened with impunity by anyone! And let it be known for all time to come that if anyone raises his hand to strike the State, then certain death is his lot.
Concerned with presenting the massacre as legally sanctioned, Hitler had the cabinet approve a measure on July 3 that declared, "The measures taken on June 30, July 1 and 2 to suppress treasonous assaults are legal as acts of self-defence by the State." Reich Justice Minister Franz Gürtner, a conservative who had been Bavarian Justice Minister in the years of the Weimar Republic, demonstrated his loyalty to the new regime by drafting the statute, which added a legal veneer to the purge. Signed into law by Hitler, Gürtner, and Minister of the Interior Wilhelm Frick, the "Law Regarding Measures of State Self-Defence" retroactively legalised the murders committed during the purge. Germany's legal establishment further capitulated to the regime when the country's leading legal scholar, Carl Schmitt, wrote an article defending Hitler's July 13 speech. It was named "The Führer Upholds the Law.". 
Question: What is the last name of the person called the Führer?
answer:

Hitler.
