[Q]: Extract the answer to the question from the following context. Question: What is the third favorable property of hydrogen listed? Context: Hydrogen is commonly used in power stations as a coolant in generators due to a number of favorable properties that are a direct result of its light diatomic molecules. These include low density, low viscosity, and the highest specific heat and thermal conductivity of all gases.

[A]: highest specific heat

[Q]: Extract the answer to the question from the following context. Question: what is the first era mentioned? Context: In the Late Empire and Middle Ages Vergilius was spelled Virgilius. Two explanations are commonly given for this alteration. One deduces a false etymology associated with the word virgo ("maiden" in Latin) due to Virgil's excessive, "maiden"-like modesty. Alternatively, some argue that Vergilius was altered to Virgilius by analogy with the Latin virga ("wand") due to the magical or prophetic powers attributed to Virgil in the Middle Ages (this explanation is found in only a handful of manuscripts, however, and was probably not widespread). In Norman schools (following the French practice), the habit was to anglicize Latin names by dropping their Latin endings, hence Virgil. In the 19th century, some German-trained classicists in the United States suggested modification to Vergil, as it is closer to his original name, and is also the traditional German spelling.[citation needed] Modern usage permits both, though the Oxford guide to style recommends Vergilius to avoid confusion with the 8th-century grammarian Virgilius Maro Grammaticus. Some post-Renaissance writers liked to affect the sobriquet "The Swan of Mantua".[citation needed]

[Q]: Extract the answer to the question from the following context. Question: Of March and April, which month has more active weather? Context: Oklahoma City has a very active severe weather season from March through June, especially during April and May. Being in the center of what is colloquially referred to as Tornado Alley, it is prone to especially frequent and severe tornadoes, as well as very severe hailstorms and occasional derechoes. Tornadoes have occurred in every month of the year and a secondary smaller peak also occurs during autumn, especially October. The Oklahoma City metropolitan area is one of the most tornado-prone major cities in the world, with about 150 tornadoes striking within the city limits since 1890. Since the time weather records have been kept, Oklahoma City has been struck by thirteen violent tornadoes, eleven F/EF4s and two F/EF5. On May 3, 1999 parts of southern Oklahoma City and nearby suburban communities suffered from one of the most powerful tornadoes on record, an F5 on the Fujita scale, with wind speeds estimated by radar at 318 mph (510 km/h). On May 20, 2013, far southwest Oklahoma City, along with Newcastle and Moore, was hit again by a EF5 tornado; it was 0.5 to 1.3 miles (0.80 to 2.09 km) wide and killed 23 people. Less than two weeks later, on May 31, another outbreak affected the Oklahoma City area, including an EF1 and an EF0 within the city and a tornado several miles west of the city that was 2.6 miles (4.2 km) in width, the widest tornado ever recorded.

[Q]: Extract the answer to the question from the following context. Question: Where did the famous kilt wearers settle? Context: The first settlers primarily came from England, its Caribbean colony of Barbados, and its Atlantic colony of Bermuda. Among these were free people of color, born in the West Indies of alliances and marriages between Africans and Englanders, when color lines were looser among the working class in the early colonial years, and some wealthy whites took black consorts or concubines. Charles Town attracted a mixture of ethnic and religious groups. French, Scottish, Irish, and Germans migrated to the developing seacoast town, representing numerous Protestant denominations. Because of the battles between English "royalty" and the Roman Catholic Church, practicing Catholics were not allowed to settle in South Carolina until after the American Revolution. Jews were allowed, and Sephardic Jews migrated to the city in such numbers that by the beginning of the 19th century, the city was home to the largest and wealthiest Jewish community in North Americaa status it held until about 1830.
