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.

Example Input: Paulo Ribenboim proved in 1991 that the set of these is Diophantine, and in 1912 Edmund Landau proposed four "unattackable problems" dealing with them, none of which have yet been solved. The theorem named for them states that the number of them less than or equal to n is approximately equal to n divided by the natural logarithm of n. The GIMPS project seeks to find examples of the Mersenne type of this number, ordinary examples of which can be found using the sieve of Eratosthenes. For 10 points, identify these numbers whose only two factors are 1 and itself.
Example Output: Social Science

Example Input: One of these organic compounds is converted to an alkene by a diorganochromium compound in the Takai olefination. Compounds may be reduced to this functionality via the use of DIBAL-H (die-bahl aitch), and alkynes are formed by a reaction of these compounds with tetrabromomethane and triphenylphosphine named for Corey and Fuchs. When these organic compounds lack a hydrogen atom in the alpha position, their disproportionation can be induced by a base in the Cannizzaro reaction. These organic compounds are oxidized to carboxylic acids by a diamminesilver (I) complex, leading to the precipitation of metal onto the inside of the vessel, giving the positive "silver mirror" result of the Tollens test. For 10 points, name this special class of ketones with one R group being just hydrogen.
Example Output: Science

Example Input: During this conflict, the Marquis of Hamilton failed to mount an amphibious invasion after his own mother threatened to shoot him if he took part. One side first camped at Birkhill and was then humiliated during a skirmish at Kelso. The initiative of Jacob Astley preserved control of Carlisle for the attackers, who secured a momentary truce called the Pacification of Berwick. The Short Parliament met between two of these events, which were instigated by a 1637 riot in St. Giles Cathedral, Edinburgh. For ten points, what failed attempt to impose Laudianism on Scotland was known by the name of the religious authorities to be reintroduced there
