In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Q: Question: In which country is the seaport city of Porto located where the wine received its name "port"? Passage:Port is produced from grapes grown and processed in the demarcated Douro region. The wine produced is then fortified by the addition of a neutral grape spirit known as aguardente to stop the fermentation, leaving residual sugar in the wine, and to boost the alcohol content. The fortification spirit is sometimes referred to as brandy but it bears little resemblance to commercial brandies. The wine is then stored and aged, often in barrels stored in a Lodge (meaning "cellar") as is the case in Vila Nova de Gaia, before being bottled. The wine received its name, "port", in the later half of the 17th century from the seaport city of Porto at the mouth of the Douro River, where much of the product was brought to market or for export to other countries in Europe. The Douro valley where port wine is produced was defined and established as a protected region, and the name Douro thus an official appellation, in 1756, making it the third oldest, after Chianti (1716) and Tokaj (1730).

Q: Question: When was the high school that Rogers graduated from founded? Passage:Rogers was born in Somerville, Massachusetts, in 1921. He graduated from Newton North High School in Newtonville in 1939. He enlisted as a private in April 1942, became an aviation cadet in August 1942, and completed pilot training and received a commission as a second lieutenant at Yuma, Arizona in 1943. During World War II, Rogers served as a P-39 Airacobra pilot with the 353rd Fighter Squadron at Hamilton Field, California He moved with the squadron to the European Theater of Operations, flew P-51 Mustang aircraft and became squadron commander. He is a fighter ace, credited with 12 enemy aircraft while flying from bases in England, Italy and France. He returned to the United States in January 1945 and was assigned to flying duties in fighter aircraft until November 1945 when he became commandant of troops at Hunter Field, Georgia. Between September 1946 and June 1947, he served as flight commander, operations officer, and commander of the 77th Fighter Squadron, 20th Fighter Group, at Shaw Air Force Base, South Carolina. He next was a student at the University of Virginia under the Air Force Institute of Technology program from July 1947 to August 1949. In August 1949 Rogers was transferred to Headquarters United States Air Force as an intelligence staff officer in the Directorate of Intelligence. He attended the language course at Lacaze Academy in Washington D.C., from October 1952 to June 1953, in preparation for attaché duties. He received a bachelor of science degree in military science from the University of Maryland in 1952. Rogers served as assistant air attach in Madrid, Spain from June 1953 to February 1957. He then returned to Headquarters United States Air Force as chief of the Current Intelligence Branch in the Office of the Deputy Chief of Staff, Operations. In 1958 he was transferred to the Organization of the Joint Chiefs of Staff as director of current intelligence, J-2, and in August 1960 entered the National War College. In July 1961 he was assigned to the Office of the Assistant Secretary of Defense with duty station at the State Department.

Q: Question: What type of joint is between the premaxillae and prefrontals? Passage:The two premaxillae are very long and run up over the snout to meet the prefrontals at the orbit. At the anterior tip they are narrow and triangular in cross-section. They form the classic rhynchosaurian beak, and there is evidence on the fossil showing that it was probably covered by a keratinous sheath. The maxilla carries a massive tooth plate and has numerous foramina for nerves and blood vessels to reach the gums through. Many of the posterior and lateral teeth are unworn from use, unlike the more anterior teeth which have been worn smooth. The nasal bones are large, but no wider than the frontals. They form a pointed posterior tip with a strong zigzag suture. The lacrimal ducts are clearly visible next to the orbit, while the lacrimal bones form much of the interior surface of the orbit. The prefrontal forms a thick eyebrow ridge, possibly as protection from predators. The jugal is complex, with four branches, and forms the anterior and ventral margins of the lower temporal fenestra. The dorsal branch forms a strong pillar behind the orbit, which has a more pronounced crest than other rhynchosaurs. The frontals are very long, and form a dish shape posteriorly. The postfrontal is triangular and forms part of the back of the orbit. The parietals are fused and have a high narrow ridge dorsally, with lateral wings extending across the upper temporal fenestrae. The postorbitals are roughly T-shaped, with three branches. Unlike Late Triassic forms, Fodonyx has a supratemporal bone. The quadratojugal and quadrate are mainly missing. One squamosal is preserved, forming much of the posterior margin of the skull. Much of the palate is intact, although the vomeronasals are quite degraded due to their length and thinness. The palatines form most of the borders of the choana. The pterygoids are very large and have three main processes, all broad and flat. The ectopterygoids are very small and hidden in palatal view. Small fragments of the hyoids are preserved, with a circular cross section and lateral striations. The basioccipital is short and attached to the narrow basisphenoid. The occipital condyle is hemispherical. Much of the detail on the paraoccipital is hard to make out due to difficulties of preparation. Only the anterior portions of the lower jaw are well preserved, but it has the typical rhynchosaur shape, curving up to the anterior tip. Teeth are mainly obscured as the jaws are tightly shut. The splenial is narrow except at the tip where it supports the symphyseal plate.
