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: 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.

Q: A functor named for this mathematician can be interpreted as the first group homology group with integral coefficients. A cellular automaton discovered by Bak, Tang, and Wiesenfeld that displays self-organized criticality is a "sandpile model" named for him. This mathematician names a class of theorems showing that various summation methods are regular, i.e., that they give the correct result for convergent series. Grothendieck introduced categories named for this mathematician in his Tohoku paper; those categories are a general setting for homological algebra and allow morphisms and objects to be added. This non-Italian mathematician gave the first complete proof of the insolubility of the quintic by radicals. Groups that satisfy the commutative law and many other mathematical concepts are named for, FTP, what Norwegian mathematician who died at the age of 26, thus making everyone else look like a chump

Q: Hans Hendrik Andersen demonstrated that the stopping power of these objects does not follow the Bethe formula, a result that proved the existence of the Barkas effect, and they are the cause of both pleochroic halos and of mineral metamictization. The last step in the CNO cycle creates a carbon atom and one of these. These are only associated with elements heavier than tellurium. Timothy May discovered that emission of these from DRAM can cause soft errors in microprocessor operations, and the Geiger-Nuttall law relates the life of an isotope to the production of these. For 10 points, identify these particles that escape from radioactive elements via quantum tunneling and Coulomb repulsion, which were used in Rutherford's gold foil experiment and are identical to a helium-4 nucleus.
