Ques: Information: - The Triassic is a geologic period and system which spans 50.9 million years from the end of the Permian Period million years ago (Mya), to the beginning of the Jurassic Period Mya. The Triassic is the first period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic was named in 1834 by Friedrich von Alberti, after the three distinct rock layers ("tri" meaning "three") that are found throughout Germany and northwestern Europered beds, capped by marine limestone, followed by a series of terrestrial mud- and sandstonescalled the "Trias". - Reptiles are tetrapod (four-limbed vertebrate) animals in the class Reptilia, comprising today's turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives. The study of these traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. - Mesosaurs ( '' middle lizards '' ) were a group of small aquatic reptiles that lived during the early Permian period , roughly 299 to 270 million years ago . Mesosaurs were the known first aquatic reptiles , having apparently returned to an aquatic lifestyle from more terrestrial ancestors . However , just how terrestrial mesosaur ancestors had become remains uncertain ; recent research can not establish with confidence if the first amniotes were fully terrestrial , or only amphibious . Most authors consider mesosaurs to have been aquatic , although at least some of them may have been amphibious , rather than completely aquatic , as indicated by their moderate skeletal adaptations to an aquatic lifestyle . They have long been thought to have been coastal forms that probably inhabited relatively shallow water , but recent research suggests that at least those from Uruguay inhabited a hypersaline environment , rather than a coastal marine environment . Recently described embryos show that pachyostosis of the ribs ( which were thicker and denser than in terrestrial tetrapods ) developed even before hatching , which suggests that mesosaurs were able to swim at birth , or shortly thereafter . They were apparently not very fast swimmers , with an optimal swimming speed estimated to have been between 0.15 and 0.86 m / s , but this must have been somewhat faster than the speed of their main prey , the pygocephalomorph crustaceans . Their reproductive mode is somewhat uncertain because association between adults and possible embryos in utero suggests viviparity , as in many aquatic reptiles , but a potentially isolated egg has also been found . Similarly , their affinities are uncertain ; they may be either the most basal sauropsids , or among the most basal parareptiles . - The Permian is a geologic period and system which spans 46.7 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 252.2 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the city of Perm. - The Crocodilia (or Crocodylia) are an order of mostly large, predatory, semiaquatic reptiles. They appeared 83.5 million years ago in the Late Cretaceous period (Campanian stage) and are the closest living relatives of birds, as the two groups are the only known survivors of the Archosauria. Members of the order's total group, the clade Pseudosuchia, appeared about 250 million years ago in the Early Triassic period, and diversified during the Mesozoic era. The order Crocodilia includes the true crocodiles (family Crocodylidae), the alligators and caimans (family Alligatoridae), and the gharial and false gharial (family Gavialidae). Although the term 'crocodiles' is sometimes used to refer to all of these, a less ambiguous vernacular term for this group is crocodilians. After reading the paragraphs above, we are interested in knowing the entity with which 'mesosaur' exhibits the relationship of 'taxon rank'. Find the answer from the choices below. Choices: - family - series
Ans: family

Ques: Information: - Deady and Villard Halls , University of Oregon are two buildings designated as U.S. National Historic Landmarks . The buildings , Deady Hall and Villard Hall , are the two oldest buildings on the campus of the University of Oregon , and were separately listed on the National Register of Historic Places in 1972 . They are located on Kincaid Street between East 11th and 12th streets . Together they were declared a National Historic Landmark in 1977 . - Villard Hall is a historic building located in Eugene, Oregon, United States. Completed in 1886, it is the second-oldest building on the University of Oregon campus after Deady Hall. The Second Empire-style building was listed on National Register of Historic Places in 1972. - Deady Hall is a historic building located in Eugene, Oregon, United States. It was built from 1873 to 1876 by W. H. Abrams to a design by architect William W. Piper. It was the University of Oregon's first building, and remained the university's only building for almost ten years after its construction. After the university gained other buildings, it was known simply as the "Old Building", but in 1893 it was renamed "Deady Hall" in honor of Matthew Deady, Oregon's first federal judge. Ironically, Deady believed that state universities were of little use to anybody, and in 1857, during the Oregon Constitutional Convention, Deady moved to strike the section authorizing a university from the Oregon State Constitution. His efforts were initially successful, although by the 1870s a state university had become inevitable, and the building that bears his name was constructed in spite of Deady's earlier objections. In another twist of fate, Deady was first president of the university's Board of Regents. - A National Historic Landmark (NHL) is a building, district, object, site, or structure that is officially recognized by the United States government for its outstanding historical significance. Of over 85,000 places listed on the country's National Register of Historic Places, only some 2,500 are recognized as National Historic Landmarks. - The University of Oregon (also referred to as UO or Oregon) is a public flagship research university in Eugene, Oregon. Founded in 1876, the institution's 295-acre campus is along the Willamette River. Since July 2014, UO has been governed by the Board of Trustees of the University of Oregon. The university has a Carnegie Classification of "highest research activity" and has 21 research centers and institutes. UO was admitted to the Association of American Universities in 1969. - The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures, and objects deemed worthy of preservation. A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred preserving the property. After reading the paragraphs above, we are interested in knowing the entity with which 'deady and villard halls' exhibits the relationship of 'located in the administrative territorial entity'. Find the answer from the choices below. Choices: - district - eugene - historic district - of - oregon - university
Ans:
eugene
