Question: Passage: After thief Alex Cardo gets caught and betrayed by his partner in crime John while stealing an ancient Jian in Thailand, he soon finds himself imprisoned and beaten. One of the guards, Demon, is particularly upset by Alex's appearance and tortures him whenever he gets the opportunity. Alex finds one friend and mentor in the jailhouse, Master Sun, who teaches him a superior fighting style called "Iron Hand". When a "best of the best kumite" is to take place, Demon gets an invitation. Now Master Sun and Alex need to find a way to let Alex take part in the kumite, too.
The final fight pits Alex and Demon together. At first, and for a long time, Demon has the upper hand in terms of strength and fighting ability. When Alex is down, he takes one last look at Master Sun and uses the "Iron Hand" against his opponent, severely damaging and defeating Demon. Alex is the winner, and as part of deals previously made, Master Sun is freed from prison, and so is Alex.
Question: What is the full name of the person who learns the "Iron Hand" fighting style?

Answer: Alex Cardo.

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 Niccolo 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: "Touch Me I'm Sick" has a straightforward garage punk structure with a simple repeating power chord riff played at a high tempo. This is accompanied by a blunt bass line and frenetic drumming. The song's dirty sound was produced using an Electro-Harmonix Big Muff distortion pedal, which is augmented by a second guitar providing more distortion. Music writer Brian J. Barr referred to this noisy sound as "the sonic equivalent of an amplified comb scraping against paper".Critics have noted a Stooges influence in "Touch Me I'm Sick", typical of Mudhoney's early material. Turner said: "In retrospect, it's The Yardbirds' 'Happenings Ten Years Time Ago' by way of The Stooges' 'Sick of You'. At the time I was trying for the stuttering R&B guitar of The Nights and Days." The song is also reminiscent of the hardcore punk of Black Flag. In his book Loser: The Real Seattle Music Story, Clark Humphrey accuses the song of being a copy of "The Witch" by The Sonics. The band have dismissed this claim, and questioned the writer's knowledge of music.Arm's lyrics, according to critic Steve Huey, are a rant about "disease, self-loathing, angst, and dirty sex". In an essay called "'Touch Me I'm Sick': Contagion as Critique in Punk and Performance Art", Catherine J. Creswell suggests that some of the lyrics refer to AIDS. According to Creswell, "In declaring 'Well, I'm diseased and I don't mind' and changing the final refrain to 'Fuck Me, I'm Sick!' the speaker declares himself to be the viral, 'AIDS-bearing,' 'polluting' person of contemporary fantasy". Creswell, who also believes the song parodies the theme of seduction in contemporary rock music, points to lyrics that refer to impotence ("If you don't come, if you don't come, if you don't come, you'll die alone!") and violent possession or forcing ("I'll make you love me till the day you die!"). However, Arm says that he had not put much thought into the lyrics; while performing the song in concerts, he sometimes changes them to amuse himself.Another feature of "Touch Me I'm Sick" that has been commented upon is Arm's vocals. Huey refers to them as a "hysterical screech", and "snarling, demonic howls". Journalist Joe Ehrbar says that Arm begins the song with a "burp", before singing with a "nasally howl". Creswell considers Arm's "overboard" vocals to mock a variety of rock stereotypes: the punk snarl, the "woozy slur" of hard rock, garage rock "yea-ahs", R&B-style wails and a "Jerry Lee Lewis shudder".
Question: What is the last name of the person who sometimes changes the lyrics to the song to amuse himself?

Answer:
Arm.
