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.

Input: Consider Input: Imetelstat, a potential new cancer therapy agent, works by targeting the enzyme that repairs these structures. Blackburn, Greider, and Szostak received the 2009 Nobel Prize for determining the role of these structures, which typically adopt a G-quadruplex shape. The shortening of these structures explains the Hayflick limit to cell division and is the basis for the cellular theory of aging, and that shortening of these structures can lead to cell senescence or apoptosis. Consisting of thousands of TTAGGG repeats in humans, name these end sequences of chromosomes that prevent genes from being lost during DNA replication.

Output: Science

Input: Consider Input: This artist depicted a certain structure "at Bellevue" and "at Montbriand". In addition to those depictions of The Pigeon House, he depicted the titular shirtless black man in jeans resting his head in one work, while a man dressed completely dressed in white gestures to a black and white harlequin in another. In addition to The Negro Scipion and Fastnacht, he created various depictions of an Avenue at (*) Chantilly, and Paul Alexis reads to one of his friends in another work. Rilke wrote some letters on this artist, who depicted a large crevice in the title structure in his House with Burst Walls, and depicted his mother knitting as his sister plays the piano in The Overture to Tannhuser. For 10 points, name this artist who was represented by Claude Lantier in The Masterpiece by Emile Zola.

Output: Fine Arts

Input: Consider Input: For the d-mode approximation associated with this effect, the Racah and Lanczos methods can be effectively applied. It is typically characterized by a parameter that is equal to 1 over h-bar omega times the energy difference between the central maxima and the distorted minima, and for substituted benzenoid cations that parameter is not usually greater than 1. The result of this effect can appear as a vertical line on a Tanabe-Sugano diagram. Where bending results in a lowering of symmetry for linear molecules, there exists a related effect named after one of this effect's namesakes and Renner. A consequence of this effect is the mixing of electronic and nuclear motions, also known as vibronic coupling, which can result in the breakdown in Born-Oppenheimer approximation. Coming in pseudo and dynamical versions, for 10 points, name this doubly-eponymous effect, which is an instability of nonlinear molecular systems in orbitally degenerate electronic states
