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.

[Q]: The retreating side tried concentrating its central forces in superior positions on hills around Pozzolengo and Guidizollo. One of the early advances was stifled by mulberry trees and grapevines, and a force under d'Hilliers advanced slightly past Castiglione before noticing the opposing army. Nine hours of fighting along a 15-mile front ensued, and after the battle the Peace of Villafranca was signed. Fought near an Italian village in 1859, FTP, name this victory for a French and Sardinian army which was witnessed by Jean-Henri Dunant, who was inspired by it to help found the Red Cross.
[A]: History


[Q]: These quantities are the arguments of the logarithms in the von Mangoldt function, which is itself summed to yield the second Chebyshev function. Using the evenly-spaced integer topology, Furstenberg re-proved that there were aleph-null many of these values. The work of Goldston et al. employing the Elliott-Halberstam conjecture was a precursor to Zhang's proof of bounded gaps between them. Thanks to the AKS algorithm, it is polytime-decidable whether or not a number is one of these numbers. The distribution of these numbers is described by the law "pi of x is asymptotic to x over log x," where "pi of x" is the function that counts these numbers. They are typically generated by sieving, as originally done by Eratosthenes. For 10 points, what numbers are divisible only by one and themselves
[A]: Science


[Q]: The conversion of methionine to S-adenosyl-L-methionine by Met Adenosyltransferase is the first step of the reaction leading to synthesis of this molecule, and the final step involves ACC-oxidase, an enzyme that is made in the presence of auxins. The first genes encoding a receptor for this molecule were found in Arabidopsis and tomatoes, and plants have a variety of responses including inhibition of stomatal closing and acceleration of fruit-ripening. In bromeliads, exposure to this chemical induces flowering, and it is used as an inhalatory anesthetic in moderate does for humans. For ten points, identify this molecule with formula C2H4, the simplest alkene.
