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: An RNA polymerase from one of these organisms is commonly used in in vitro transcription experiments, and one well-studied example of these organisms uses the Q antiterminator to transcribe its structural components. Benzer's rII system uses these organisms for single-nucleotide mutation mapping, and the Phi-X-174 example of these organisms was the first to have its genome (*) sequenced. These organisms carry genetic information between cells in transduction. These organisms were labeled with 32P and 35S in the experiment that showed that DNA is the substance that stores genetic information, performed by Hersey and Chase. These organisms use their tail proteins as an injection mechanism. For 10 points, name these viruses that infect bacteria.

Output: Science


Input: Consider Input: The oxidation of one of these compounds with a Jones reagent yields carboxylic acid, and they are the product of the reaction of a ketone with a Grignard reagent. Esters are formed via a reaction of carboxylic acid and this compound in a process named for Fischer. Consisting of a hydroxyl group bonded to a carbon atom, they are given the formula R-OH. For 10 points, name this class of compounds exemplified by methanol and ethanol, the latter of which is found in hand sanitizer and beer.

Output: Science


Input: Consider Input: One variety of them formed from secondary imines such as pyrimidine are named for Zincke. Two equivalents of these compounds yield a carboxylic acid and a primary alcohol in a disproportion reaction named for Cannizaro. They are characterized by an NMR shift of about 9 to 10 ppm, and their oxidation in the presence of a diamine-silver complex yields a "silver mirror" in the Tollens test. For 10 points, identify this functional group which features a carbon double bonded to an oxygen atom and single bonded to a hydrogen atom, exemplified by methanal and ethanal.
