PROBLEM: Passage: A musician named Dixie Dwyer begins working with mobsters to advance his career but falls in love with the girlfriend of gangland kingpin Dutch Schultz.
A dancer from Dixie's neighborhood, Sandman Williams, is hired with his brother by the Cotton Club, a jazz club where most of the performers are black and the customers white. Owney Madden, a mobster, owns the club and runs it with his right-hand man, Frenchy.
Dixie becomes a Hollywood film star, thanks to the help of Madden and the mob but angering Schultz. He also continues to see Schultz's moll, Vera Cicero, whose new nightclub has been financed by the jealous gangster.
In the meantime, Dixie's ambitious younger brother Vincent becomes a gangster in Schultz's mob and eventually a public enemy, holding Frenchy as a hostage.
Sandman alienates his brother Clay at the Cotton Club by agreeing to perform a solo number there. While the club's management interferes with Sandman's romantic interest in Lila, a singer, its cruel treatment of the performers leads to an intervention by Harlem criminal "Bumpy" Rhodes on their behalf.
Dutch Schultz is violently dealt with by Madden's men while Dixie and Sandman perform on the Cotton Club's stage. 
Question: How does the dancer know Clay?

SOLUTION: his brother.

PROBLEM: Passage: Axel Nordstrom manages a glass-bottom boat tourist operation in the waters of Santa Catalina Island, California. His widowed daughter, Jennifer Nelson, occasionally helps by donning a mermaid costume and swimming underneath his boat for the passengers' amusement.
One day, Jennifer accidentally meets Bruce Templeton when his fishing hook snags her costume. He reels in the bottom half, leaving the irate Jennifer floating in the water without pants. Jennifer later discovers that Templeton is a top executive at her new place of employment, a NASA aerospace research laboratory in Long Beach, where she works in public relations.
Templeton later recognizes Jennifer at the research laboratory and hires her for a new full-time assignment: to be his biographer and write his life story. His real purpose is to win her affections. There is a problem: the laboratory's security chief, Homer Cripps, after observing her mysterious behavior and curious, code-like phone calls, concludes that Jennifer is a Soviet spy. To prove his suspicions, he has Jennifer put under surveillance by everyone at the lab. When she learns of this, Jennifer sets out to turn the tables on the bumbling Cripps by pretending that she is a spy, a charade that eventually exposes a real spy. 
Question: What is the full name of the character whose daughter occasionally swims in a mermaid costume.?

SOLUTION: Axel Nordstrom.

PROBLEM: Passage: Bach is known as a prolific composer of cantatas. When he assumed the position as Thomaskantor (director of church music) in Leipzig in 1723, he began the project to write church cantatas for the occasions of the liturgical year – Sundays and feast days – a project that he pursued for three years.Bach was appointed organist and chamber musician in Weimar at the court of the co-reigning dukes in Saxe-Weimar, Wilhelm Ernst and his nephew Ernst August on 25 June 1708. He had composed sacred cantatas before, some during his tenure in Mühlhausen from 1706 to 1708. Most were written for special occasions and were based mainly on biblical texts and hymns. Examples include: Aus der Tiefen rufe ich, Herr, zu dir, BWV 131; the early chorale cantata Christ lag in Todes Banden, BWV 4 for Easter; Gott ist mein König, BWV 71, to celebrate the inauguration of the new city council on 4 February 1708; and the Actus Tragicus for a funeral.
In Weimar, Bach first concentrated on the organ, composing major works for the instrument, including the Orgelbüchlein, the Toccata and Fugue in D minor, BWV 565, and the Prelude and Fugue in E major, BWV 566. Christoph Wolff suggests that Bach may have studied musical material belonging to the Hofkapelle, ("court capelle" or court orchestra), and that he copied and studied works by Johann Philipp Krieger, Christoph Graupner, Georg Philipp Telemann, Marco Giuseppe Peranda and Johann David Heinichen in the period from 1711 to 1713. In early 1713 Bach composed his first cantatas in the new style that included recitatives and arias: the so-called Hunting Cantata, BWV 208, as a homage cantata for Christian, Duke of Saxe-Weissenfels, celebrated on 23 February, and possibly the church cantata for Sexagesima (the second Sunday before Lent) Gleichwie der Regen und Schnee vom Himmel fällt, BWV 18, on a text by Erdmann Neumeister.In 1713, he was asked to apply for the position of music director of the Marktkirche in Halle, succeeding Friedrich Wilhelm Zachow. Zachow had taught the young George Frideric Handel, and  composed many church cantatas in the new style, adopting recitatives and arias from the Italian opera. Bach was successful in his application for the position, but declined after Duke Wilhelm Ernst increased his salary and offered him a promotion. 
Question: What is the last name of the person who succeeded Friedrich Wilhelm Zachow?

SOLUTION:
Bach.
