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: This enzyme is degraded by the actions of victorin and the DNA-binding aspartic acid peptidase CND41, but is forced into a proteolysis-resistant state by the binding of its inhibitor CA1P. It is usually localized to to pyrenoids, and a lysine residue on it is carbamated by its namesake activase, which allows the positioning of a critical magnesium molecule. Phosphoglycolate is a side product of this enzyme, whose slow speed and penchant for leading to photorespiration is counteracted by PEP carboxylase in some organisms. FTP, name this enzyme, the most abundant protein on earth, that catalyzes a major step in the Calvin cycle by attaching a carbon dioxide molecule to Ribulose bisphosphate.

SOLUTION: Science

PROBLEM: Haldan Keffer Hartline won a Nobel Prize for his research on the electrical responses of this object in horseshoe crabs. This object contains Muller glia, which are mitotically active following damage to it. Coats disease causes the separation of this object and a cherry-red spot is found on it in children with Tay-Sachs disease. Horizontal and amacrine cells modulate communication between its cells, the inner layer of which contains ganglion cells. Composed of neural tissue, this innermost layer of the eye has a depression in its center called the macula. For 10 points, name this location of photoreceptors such as rods and cones.

SOLUTION: Science

PROBLEM: The greatest Doubletree hotel in the world occupies this city's Arctic Club building, whose facade is lined with terra cotta walrus heads. It's not New York, but a flatiron-shaped building in this city is called the Times Square Building. Elevator operators still work at this city's oldest skyscraper, the pyramid-capped Smith Tower. A library in this city includes a four-story [*] "Book Spiral" that houses its collection along a continuous line. The 1962 World's Fair, was held in this city, prompting the construction of an observation tower that is now located near a Paul Allen-sponsored building resembling a smashed Stratocaster. This city's Central Library was designed by Rem Koolhas, and Frank Gehry designed its Experience Music Project. For 10 points, name this home of the Space Needle.
