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: Josh and Dinah Barkley (Fred Astaire and Ginger Rogers) are a husband-and-wife musical comedy team at the peak of their careers. After finishing a new show, Dinah meets serious French playwright Jacques Pierre Barredout, who suggests that Dinah should take up dramatic acting. Dinah tries to keep the suggestion a secret from Josh, but when he finally discovers Dinah hiding a script for Jacques' new show from him, the couple splits up.  
Their good friend, acerbic composer Ezra Miller tries to trick them back together again, but fails.  When Josh secretly watches Dinah's rehearsals for Barredout's new play and sees how she is struggling, he calls her up and pretends to be the Frenchman, giving her notes that help her to understand her part, the young Sarah Bernhardt. As the result, Dinah gives a brilliant performance. After the show, she accidentally learns that her late-night mentor was Josh and not Barredout, so she rushes to Josh's apartment and the two reconcile. 
Question: What is the last name of the late-night mentor?

A: Barkley.

Q: Passage: Right before Berk's traditional winter holiday of Snoggletog, all the dragons of Berk unexpectedly depart, leaving everyone distraught - except for Toothless, who cannot fly by himself. Out of compassion, Hiccup builds him a new automatic prosthesis allowing him independent flight, thus gifting him his freedom; he then flies off too.
Three days later, Meatlug, Fishlegs's dragon whom he had secretly kept chained, escapes, inadvertently taking Hiccup with him. Meatlug flies to an island with hot springs, where all the dragons (except Toothless, whom is nowhere to be found) have been hatching their eggs. Meanwhile, on Berk, Astrid and the other youth discover dragon eggs in Meatlug's nest, which they scatter around Berk in hopes of lifting the villagers' spirits; this plan backfires because dragon eggs hatch explosively (normally underwater), devastating Berk.
On the dragons' island, Hiccup meets Stormfly (Astrid's dragon) and Hookfang (Snotlout's dragon) and their newly-hatched babies; in asking for a ride home, he inadvertently triggers the dragons' return migration. He quickly decides to use a nearby wrecked ship to carry the baby dragons who cannot yet fly all the way back to Berk. The Berkians are overjoyed at their dragons' return and the new babies; yet, Hiccup is still distraught at Toothless's absence. During the ensuing Snoggletog celebration, Toothless returns with Hiccup's lost helmet, which he had dropped into the sea earlier; the two enjoy a heartfelt reunion.
The next day, Toothless destroys his new tail, begging Hiccup to put the old tailfin on him and fly with him by controlling his fin manually as opposed to merely on him; in doing so, he gives Hiccup a "better gift" - his friendship and companionship. 
Question: Who's helmet does the dragon that requires a prosthesis bring back?

A:
Hiccup.
