PROBLEM: 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?

SOLUTION: Donald.

PROBLEM: Passage: Agnes Hurley is a disillusioned housewife, married to Bronx cabdriver Tom Hurley. She wants something better for her daughter, Jane. When Jane announces her engagement to Ralph Halloran, Aggie sees this as an opportunity to have a romantic elaborate wedding, with caterers and all the trimmings, like she never had because they could never afford it. However, the daughter does not want it because it is causing awkward conflicts with her family and friends, and her father has been saving that money for many years to purchase a taxi medallion and become self-employed. The film deals with the ensuing money troubles and conflicts within the family, which also involve Uncle Jack Conlon and most of the neighborhood. It is not until the end of the film that the mother realizes that it is the happiness of her family, rather than the expensive ceremony, that is most important, as they go off to watch their daughter get married at their church in the new taxi. 
Question: What's the name of the person who refuses Agnes Hurley's wishes for an elaborate wedding?

SOLUTION: Jane.

PROBLEM: Passage: The origins of the Early Netherlandish school lie in the miniature paintings of the late Gothic period.  This was first seen in manuscript illumination, which after 1380 conveyed new levels of realism, perspective and skill in rendering colour, peaking with the Limbourg brothers and the Netherlandish artist known as Hand G, to whom the most significant leaves of the Turin-Milan Hours are usually attributed. Although his identity has not been definitively established, Hand G, who contributed c. 1420, is thought to have been either Jan van Eyck or his brother Hubert. According to Georges Hulin de Loo, Hand G's contributions to the Turin-Milan Hours "constitute the most marvelous group of paintings that have ever decorated any book, and, for their period, the most astounding work known to the history of art".Jan van Eyck's use of oil as a medium was a significant development, allowing artists far greater manipulation of paint. The 16th-century art historian Giorgio Vasari claimed van Eyck invented the use of oil paint; a claim that, while exaggerated, indicates the extent to which van Eyck helped disseminate the technique. Van Eyck employed a new level of virtuosity, mainly from taking advantage of the fact that oil dries so slowly; this gave him more time and more scope for blending and mixing layers of different pigments, and his technique was quickly adopted and refined by both Robert Campin and Rogier van der Weyden. These three artists are considered the first rank and most influential of the early generation of Early Netherlandish painters. Their influence was felt across northern Europe, from Bohemia and Poland in the east to Austria and Swabia in the south. 
Question: WHat is the first name of the person who was said to have invented the use of oil paint?

SOLUTION:
Jan.
