TASK DEFINITION: In this task you will be given a text passage from a trivia quiz. You should choose the category this question belongs to from these categories: History, Science, Social Science, Fine Arts, Literature. You can only choose one category, so if in doubt, please choose the closest match.
PROBLEM: One reactant for this reaction is best prepared by an S N 2 nucleophilic addition of a triphenyl compound, followed by elimination of the hydrogen halide by an organolithium reagent. This reaction itself proceeds through a rather unique intermediate formed when the pi electron from the reagents carbon-oxygen double bond migrates to the positively charged pole of one reactant; this intermediate is called a an oxaphosphetane, from which a triphenyl oxide is eliminated to complete the reaction. The aforementioned positively charged pole is on phosphorous because the aforementioned prepared reactant is a phosphorous ylide. For ten points, name this reaction that produces selectively double-bonded alkenes from aldehydes and phosphorous ylides and that is named for the German 1979 Chemistry Nobel winner.

SOLUTION: Science

PROBLEM: Three of the islands in this group voted for independence in 1975, while Mayotte chose to remain a French dependency. Its first president was Ahmed Abdallah Abderrahman, who was assassinated in 1989. Its highest peak is Karthala, a still-active volcano on the largest island of this group. Other islands include Mwali and Nzwani, which were formerly known as Anjouan and Mohli. Located at the northern end of the Mozambique Channel, FTP, identify this island nation with capital at Moroni.

SOLUTION: Social Science

PROBLEM: This painter showed a woman looking at the apparition of a head appearing above a lion-clothed man, who steps over a crown and putto in the Allegory of Wisdom and Strength. He included The Triumph of Mordecai and The Banishment of Vashti in his History of Esther series. Dogs line the foreground of another work in which a man bowing a viola d'amore stands in front of a star-haloed Jesus, who has just created the wine being poured on the right. This artist painted a similarly crowded scene for the Basilica di Santi Giovanni e Paolo, but was forced to have its title changed from "The Last Supper" by the Inquisition. For 10 points, name this Italian painter who created Wedding at Cana and Feast in the House of Levi.
