Q: 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?

A: Alex Cardo.

Q: Passage: Carmen (French pronunciation: ​[kaʁmɛn]; Spanish: [ˈkaɾmen]) is an opera in four acts by French composer Georges Bizet. The libretto was written by Henri Meilhac and Ludovic Halévy, based on a novella of the same title by Prosper Mérimée. The opera was first performed by the Opéra-Comique in Paris on 3 March 1875, where its breaking of conventions shocked and scandalized its first audiences.
Bizet died suddenly after the 33rd performance, unaware that the work would achieve international acclaim within the following ten years.  Carmen has since become one of the most popular and frequently performed operas in the classical canon;  the "Habanera" from act 1 and the "Toreador Song" from act 2 are among the best known of all operatic arias.
The opera is written in the genre of opéra comique with musical numbers separated by dialogue. It is set in southern Spain and tells the story of the downfall of Don José, a naïve soldier who is seduced by the wiles of the fiery gypsy Carmen. José abandons his childhood sweetheart and deserts from his military duties, yet loses Carmen's love to the glamorous torero Escamillo, after which José kills her in a jealous rage. The depictions of proletarian life, immorality, and lawlessness, and the tragic death of the main character on stage, broke new ground in French opera and were highly controversial.
After the premiere, most reviews were critical, and the French public was generally indifferent. Carmen initially gained its reputation through a series of productions outside France, and was not revived in Paris until 1883. Thereafter, it rapidly acquired popularity at home and abroad. Later commentators have asserted that Carmen forms the bridge between the tradition of opéra comique and the realism or verismo that characterised late 19th-century Italian opera.
The music of Carmen has since been widely acclaimed for brilliance of melody, harmony, atmosphere, and orchestration, and for the skill with which Bizet musically represented the emotions and suffering of his characters. After the composer's death, the score was subject to significant amendment, including the introduction of recitative in place of the original dialogue; there is no standard edition of the opera, and different views exist as to what versions best express Bizet's intentions. The opera has been recorded many times since the first acoustical recording in 1908, and the story has been the subject of many screen and stage adaptations. 
Question: What year was the first acoustical recording of the opera that has been widely acclaimed for brilliance of melody?

A: 1908.

Q: Passage: Danny Kaye plays a double role as a pair of estranged "super-identical (monozygotic) twins", with very similar looks, but very different personalities. Buster Dingle, who goes by the stage name "Buzzy Bellew", is a loud and goofy performer at a classy nightclub (the Pelican Club), while Edwin Dingle is a studious, quiet bookworm writing a history book. The two brothers have not seen each other for years.
Buster becomes the witness to a murder committed by mob boss "Ten Grand" Jackson, and is promptly murdered himself. He comes back as a ghost, calling on his long-lost brother for help to bring the killer to justice. As a result, the shy Edwin must take his brother's place until after his testimony is given.
In the meantime, he has to dodge Jackson's hitmen and fill in for Buster at the nightclub. To help him out, Buster—who cannot be seen or heard by anyone but Edwin—possesses him, with outrageously goofy results.
A famous scene features Edwin, possessed by Buzzy, performing at the Club. Under Buzzy's influence, Edwin pretends to be a famous Russian singer with an allergy to flowers. A vase of flowers is nonetheless placed on a table near him, and his song, "Otchi Chornya", is frequently interrupted by his loud and goofy-sounding sneezes.
The story is further humorously complicated by the love interests of the brothers; whilst the murdered Buster was engaged to entertainer Midge Mallon, Edwin is admired by librarian Ellen Shanley.
In the end, Ellen marries Edwin, whilst Midge consoles herself (apparently without regret) by marrying the owner of the club where Buster was appearing. 
Question: What is the real name of the person that influences a studious bookworm to pretend to be a Russian singer?

A:
Buster Dingle.
