Q: Information: - Clostridium is a genus of Gram-positive bacteria, which includes several significant human pathogens, including the causative agent of botulism and an important cause of diarrhea, "Clostridium difficile". They are obligate anaerobes capable of producing endospores. The normal, reproducing cells of "Clostridium", called the vegetative form, are rod-shaped, which gives them their name, from the Greek or spindle. "Clostridium" endospores have a distinct bowling pin or bottle shape, distinguishing them from other bacterial endospores, which are usually ovoid in shape. "Clostridium" species inhabit soils and the intestinal tract of animals, including humans. "Clostridium" is a normal inhabitant of the healthy lower reproductive tract of women. - The Firmicutes (Latin: "firmus", strong, and "cutis", skin, referring to the cell wall) are a phylum of bacteria, most of which have Gram-positive cell wall structure. A few, however, such as "Megasphaera", "Pectinatus", "Selenomonas" and "Zymophilus", have a porous pseudo-outer membrane that causes them to stain Gram-negative. Scientists once classified the Firmicutes to include all Gram-positive bacteria, but have recently defined them to be of a core group of related forms called the low-G+C group, in contrast to the Actinobacteria. They have round cells, called cocci (singular coccus), or rod-like forms (bacillus). - Peptostreptococcaceae is a family of Gram positive bacteria in the class Clostridia . - The Clostridia are a highly polyphyletic class of Firmicutes, including "Clostridium" and other similar genera. They are distinguished from the Bacilli by lacking aerobic respiration. They are obligate anaerobes and oxygen is toxic to them. Species of the genus "Clostridium" are often but not always Gram-positive (see "Halanaerobium hydrogenoformans") and have the ability to form spores. Studies show they are not a monophyletic group, and their relationships are not entirely certain. Currently, most are placed in a single order called Clostridiales, but this is not a natural group and is likely to be redefined in the future. - Bacilli refers to a taxonomic class of bacteria. It includes two orders, Bacillales and Lactobacillales, which contain several well-known pathogens such as "Bacillus anthracis" (the cause of anthrax). All "Bacilli" are gram-positive bacteria. After reading the paragraphs above, we are interested in knowing the entity with which 'peptostreptococcaceae' exhibits the relationship of 'parent taxon'. Find the answer from the choices below. Choices: - bacillales - bacilli - bacteria - clostridia - clostridiales - clostridium - firmicutes - human - lactobacillales - pectinatus - zymophilus
A: clostridiales

Q: Information: - Coburg is a town located on the Itz river in the Upper Franconia region of Bavaria, Germany. Long part of one of the Thuringian states of the Wettin line, it joined Bavaria by popular vote only in 1920. Until the revolution of 1918, it was one of the capitals of the Duchy of Saxe-Coburg and Gotha and the Duchy of Saxe-Coburg-Saalfeld. Through successful dynastic policies, the ruling princely family married into several of the royal families of Europe, most notably in the person of Prince Albert, who married Queen Victoria in 1840. As a result of these close links with the royal houses of Europe in the late 19th and early 20th centuries, Coburg was frequently visited by the crowned heads of Europe and their families. - Franconia (also called "Frankenland") is a region in Germany, characterised by its culture and language, and may be roughly associated with the areas in which the East Franconian dialect group, locally referred to as "frankisch", is spoken. It commonly refers to the eastern part of the historical Franconian stem duchy, mainly represented by the modern Bavarian administrative districts of Lower, Middle, and Upper Franconia, the adjacent northeastern parts of Heilbronn-Franken in Baden-Wurttemberg, parts of Thuringia south of the Rennsteig ridge, and small parts of Hesse. However, there is no fixed area that is officially defined as Franconia. - Saalfeld is a town in Germany, capital of the Saalfeld-Rudolstadt district of Thuringia. It is best known internationally as the ancestral seat of the Saxe-Coburg and Gotha branch of the Saxon House of Wettin, which was renamed the House of Windsor during their British reign in 1917. - Princess Victoria of Saxe - Coburg - Saalfeld ( Marie Luise Victoire ; 17 August 1786 -- 16 March 1861 ) was a German princess and the mother of Queen Victoria of the United Kingdom . After reading the paragraphs above, we are interested in knowing the entity with which 'princess victoria of saxe-coburg-saalfeld' exhibits the relationship of 'noble family'. Find the answer from the choices below. Choices: - house of wettin - wurttemberg
A: house of wettin
