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: LDA is used to transform propargyl diol into one of these compounds in the Whiting reaction. A  useful one of these compounds is synthesized using zinc chloride to combine trimethylsilyl chloride  with methoxybutenone. The namesake value of these compounds is expressed as the mass of iodine  equivalent to the amount of (*) maleic anhydride reacting with a unit mass of one of these. The  cumulated type of these compounds are less stable than other types. Electrophilic addition can result in  both 1,2 and 1,4 additions in the conjugated type of these molecules. That type also undergoes a type of  reaction that follows the endo addition rule and forms cyclohexenes, the Diels-Alder reaction. For 10  points, name these hydrocarbons that contain two carbon-carbon double bonds.

SOLUTION: Science

PROBLEM: This artist depicted the remnants of a tree hanging over the edge of a cliff after a lightning strike in Storm in the Mountains, and he showed a man walking toward the titular structure high on a cliff in The Monastery of San Pedro. His former home Olana is now a tourist site, and no single place inspired the setting of Twilight in the Wilderness. Various trips led to many of his works, including The Icebergs and Falls of Tequendama, as well as images of the volcanos Chimborozo and Cotopaxi. For ten points, name this student of Thomas Cole who painted a famous version of some New York falls in Niagara  and an idealized South American landscape in Heart of the Andes.

SOLUTION: Fine Arts

PROBLEM: Proteins destined for these structures are post-translationally modified to include mannose-6-phosphate residues on their N-linked oligosaccharides. The addition of the M6P tag to enzymes, such as aryl-sulfytase A, is being investigated as a potential treatment for diseases that affect these organelles, which diseases include metachromatic leukodystrophy and Fabry's disease. Once inside these structures, the proteins and their M6P tags dissociate due to the environment created by vacuolar ATPase, which is closely related to the proton pump used in oxidative phosphorylation. FTP, identify these organelles containing hydrolases that function best at a pH of about 5 and which are structurally similar to peroxisomes.
