Question: The Mantoux tuberculin skin test is often used to screen people at high risk for TB. Those who have been previously immunized may have a false-positive test result. The test may be falsely negative in those with sarcoidosis, Hodgkin's lymphoma, malnutrition, and most notably, active tuberculosis. Interferon gamma release assays (IGRAs), on a blood sample, are recommended in those who are positive to the Mantoux test. These are not affected by immunization or most environmental mycobacteria, so they generate fewer false-positive results. However, they are affected by M. szulgai, M. marinum, and M. kansasii. IGRAs may increase sensitivity when used in addition to the skin test, but may be less sensitive than the skin test when used alone.
Is there an answer to this question: In combination with skin tests, are IGRAs associated with an increase or decrease in sensitivity?

Answer: increase


Question: There were two distinct lines of Enlightenment thought: the radical enlightenment, inspired by the philosophy of Spinoza, advocating democracy, individual liberty, freedom of expression, and eradication of religious authority; and a second, more moderate variety, supported by René Descartes, John Locke, Christian Wolff, Isaac Newton and others, which sought accommodation between reform and the traditional systems of power and faith. Both lines of thought were opposed by the conservative Counter-Enlightenment.

Question: On 16 March 2012, 52 Greenpeace activists from five different countries boarded Fennica and Nordica, multipurpose icebreakers chartered to support Shell's drilling rigs near Alaska. Around the same time period, a reporter for Fortune magazine spoke with Edward Itta, an Inupiat Eskimo leader and the former mayor of the North Slope Borough, who expressed that he was conflicted about Shell's plans in the Arctic, as he was very concerned that an oil spill could destroy the Inupiat Eskimo's hunting-and-fishing culture, but his borough also received major tax revenue from oil and gas production; additionally, further revenue from energy activity was considered crucial to the future of the living standard in Itta's community.
Is there an answer to this question: How many Greenpeace activists boarded Fennica and Nordica in March 2012?

Answer: 52


Question: Roman city life and culture changed greatly in the early Middle Ages. Although Italian cities remained inhabited, they contracted significantly in size. Rome, for instance, shrank from a population of hundreds of thousands to around 30,000 by the end of the 6th century. Roman temples were converted into Christian churches and city walls remained in use. In Northern Europe, cities also shrank, while civic monuments and other public buildings were raided for building materials. The establishment of new kingdoms often meant some growth for the towns chosen as capitals. Although there had been Jewish communities in many Roman cities, the Jews suffered periods of persecution after the conversion of the empire to Christianity. Officially they were tolerated, if subject to conversion efforts, and at times were even encouraged to settle in new areas.
Is there an answer to this question: What new use was found for Roman temples?

Answer:
Christian churches
