Q: Passage: Donald's Dilemma starts with Daisy narrating her problem to an unseen psychologist through flashback scenes. Her problem started on a spring day when she was out on a date with Donald and a flower pot fell on his head. He regained consciousness soon enough but with some marked differences. His singing voice was improved to the degree in which it sounds identical to Frank Sinatra. However, Donald had no memory of who Daisy was. He became a well-known crooner and his rendition of "When You Wish Upon a Star" from Pinocchio (which had been released seven years earlier) became a hit, which gave him a large number of fans. Daisy's loss resulted in a number of psychological symptoms - she suffered from anorexia, insomnia and self-described insanity. An often censored scene features her losing her will to live and pointing a gun at her head, while in front of a table of other different suicidal methods, including a noose, a grenade, a bomb, a knife, and poison. She decided that she would see Donald once again, at any cost, but failed to do so. That's when she decided to go to the psychologist - and the flashback meets the actual time of the cartoon.
At the end of the cartoon, the psychologist determines that Donald would regain his memory of Daisy if another flower pot (with the same flower from the first pot, which Daisy kept as the only thing she had to remember Donald) would fall on his head. But he warns that his improved voice may be lost along with his singing career. He offers Daisy a dilemma. Either the world has its singer but Daisy loses him or Daisy regains Donald but the world loses him. Posed with the question "her or the world", Daisy answers with a resounding and possessive scream - "Me! Me! Me! MEEE!!". Soon, Donald returns to his old self and forgets about his singing career and Daisy regains her lover. 
Question: Whose singing voice improved after being hit on the head with a flower pot?

A: Donald.

Q: Passage: Another letter to The New York Times blamed the shark infestation on the maneuvers of German U-boats near America's East Coast. The anonymous writer claimed, "These sharks may have devoured human bodies in the waters of the German war zone and followed liners to this coast, or even followed the Deutschland herself, expecting the usual toll of drowning men, women, and children." The writer concluded, "This would account for their boldness and their craving for human flesh."Decades later, there is no consensus among researchers over Murphy and Lucas's investigation and findings. Richard G. Fernicola published two studies of the event, and notes that "there are many theories behind the New Jersey attacks," and all are inconclusive. Researchers such as Thomas Helm, Harold W. McCormick, Thomas B. Allen, William Young, Jean Campbell Butler, and Michael Capuzzo generally agree with Murphy and Lucas. However, the National Geographic Society reported in 2002 that "some experts are suggesting that the great white may not in fact be responsible for many of the attacks pinned on the species. These people say the real culprit behind many of the reported incidents—including the famous 1916 shark attacks in New Jersey that may have served as inspiration for Jaws—may be the lesser known bull shark."Biologists George A. Llano and Richard Ellis suggest that a bull shark could have been responsible for the fatal Jersey Shore attacks. Bull sharks swim from the ocean into freshwater rivers and streams and have attacked people around the world. In his book Sharks: Attacks on Man (1975), Llano writes,
One of the most surprising aspects of the Matawan Creek attacks was the distance from the open sea. Elsewhere in the book are accounts of well-documented shark-human interactions at Ahwaz, Iran, which is 90 miles (140 km) upriver from the sea. It may also be of interest to note that sharks live in Lake Nicaragua, a fresh-water body, and in 1944 there was a bounty offered for dead freshwater sharks, as they had "killed and severely injured lake bathers recently."
Ellis points out that the great white "is an oceanic species, and Schleisser's shark was caught in the ocean. To find it swimming in a tidal creek is, to say the least, unusual, and may even be impossible. The bull shark, however, is infamous for its freshwater meanderings, as well as for its pugnacious and aggressive nature."  He admits that "the bull shark is not a common species in New Jersey waters, but it does occur more frequently than the white."In an interview with Michael Capuzzo, ichthyologist George H. Burgess surmises, "The species involved has always been doubtful and likely will continue to generate spirited debate." Burgess, however, does not discount the great white:. 
Question: What is the full name of the book with accounts of well-documented shark-human interactions at Ahwaz, Iran?

A: Sharks: Attacks on Man.

Q: Passage: While driving his Dual-Ghia from Las Vegas to Los Angeles, lecherous, heavy-drinking pop singer Dino is forced to detour through Climax, Nevada. There he meets the amateur songwriting team of Barney Millsap, a gas station attendant, and piano teacher Orville J. Spooner, a man easily given to jealousy. Hoping to interest Dino in their songs, Barney disables the "Italian" sports car and tells Dino he will need to remain in town until new parts arrive from Milan. (Dual-Ghia was actually an American marque, mating a Dodge frame, drivetrain, and engine with Italian coachwork.)
Orville invites Dino to stay with him and wife Zelda, but becomes concerned when he learns the singer needs to have sex every night to avoid awakening with a headache. Anxious to accommodate Dino but safeguard his marriage, Orville provokes an argument with his wife that leads to Zelda fleeing in tears. He and Barney then arrange for Polly the Pistol, a waitress and prostitute at a saloon on the edge of town called the Belly Button, to pose as Orville's wife and satisfy Dino.
That evening after the three have dinner, Orville plays his tunes for Dino on the piano and Polly requests a particular song. It is one she knows he wrote for his wife when trying to persuade her to marry him. Doing so, Orville gets lost in emotion, as does Polly, who has fallen a little for the dream of a domestic life that she doesn't have. Under the influence of wine and song, Orville starts thinking of Polly as his wife and tosses Dino out. He then spends the night with Polly. 
Question: What is the last name of the person who invites Dino to stay with him?

A:
Spooner.
