Q: 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.?

A: Axel Nordstrom.

Q: Passage: As the national media descended on Beach Haven, Spring Lake, and Matawan, the Jersey Shore attacks started a shark panic. According to Capuzzo, this panic was "unrivaled in American history," "sweeping along the coasts of New York and New Jersey and spreading by telephone and wireless, letter and postcard." At first, after the Beach Haven incident, scientists and the press reluctantly blamed the death of Charles Vansant on a shark. The New York Times reported that Vansant "was badly bitten in the surf ... by a fish, presumably a shark." Still, State Fish Commissioner of Pennsylvania and former director of the Philadelphia Aquarium James M. Meehan asserted in the Philadelphia Public Ledger that the shark was preying on the dog, but bit Vansant by mistake. He specifically de-emphasized the threat sharks posed to humans:
Despite the death of Charles Vansant and the report that two sharks having been caught in that vicinity recently, I do not believe there is any reason why people should hesitate to go in swimming at the beaches for fear of man-eaters. The information in regard to the sharks is indefinite and I hardly believe that Vansant was bitten by a man-eater. Vansant was in the surf playing with a dog and it may be that a small shark had drifted in at high water, and was marooned by the tide. Being unable to move quickly and without food, he had come in to bite the dog and snapped at the man in passing.
The media's response to the second attack was more sensational. Major American newspapers such as the Boston Herald, Chicago Sun-Times, The Philadelphia Inquirer, The Washington Post and San Francisco Chronicle placed the story on the front page. The New York Times' headline read, "Shark Kills Bather Off Jersey Beach". The growing panic had cost New Jersey resort owners an estimated $250,000 ($5,800,000 in 2018) in lost tourism, and sun bathing had declined by 75 percent in some areas. A press conference was convened on July 8, 1916, at the American Museum of Natural History with scientists Frederic Augustus Lucas, John Treadwell Nichols, and Robert Cushman Murphy as panelists. To calm the growing panic, the three men stressed that a third run in with a shark was unlikely, although they were admittedly surprised that sharks bit anyone at all. Nevertheless, Nichols—the only ichthyologist in the trio—warned swimmers to stay close to shore and to take advantage of the netted bathing areas installed at public beaches after the first attack. 
Question: What are the full names of the three men who were admittedly surprised that sharks bit anyone at all?

A: Frederic Augustus Lucas.

Q: Passage: American music critic and journalist Harold C. Schonberg wrote of Tchaikovsky's "sweet, inexhaustible, supersensuous fund of melody," a feature that has ensured his music's continued success with audiences. Tchaikovsky's complete range of melodic styles was as wide as that of his compositions. Sometimes he used Western-style melodies, sometimes original melodies written in the style of Russian folk song; sometimes he used actual folk songs. According to The New Grove, Tchaikovsky's melodic gift could also become his worst enemy in two ways. The first challenge arose from his ethnic heritage. Unlike Western themes, the melodies that Russian composers wrote tended to be self-contained; they functioned with a mindset of stasis and repetition rather than one of progress and ongoing development. On a technical level, it made modulating to a new key to introduce a contrasting second theme exceedingly difficult, as this was literally a foreign concept that did not exist in Russian music. The second way melody worked against Tchaikovsky was a challenge that he shared with the majority of Romantic-age composers. They did not write in the regular, symmetrical melodic shapes that worked well with sonata form, such as those favored by Classical composers such as Haydn, Mozart or Beethoven, but were complete and independent in themselves. This completeness hindered their use as structural elements in combination with one another. This challenge was why the Romantics "were never natural symphonists". All a composer like Tchaikovsky could do with them was to essentially repeat them, even when he modified them to generate tension, maintain interest and satisfy listeners. 
Question: What is the name of the person who sometimes used original melodies written in the style of Russian folk song?

A:
Tchaikovsky.
