Article: Described as being "sexy, seductive and provocative" when performing on stage, Beyoncé has said that she originally created the alter ego "Sasha Fierce" to keep that stage persona separate from who she really is. She described Sasha as being "too aggressive, too strong, too sassy [and] too sexy", stating, "I'm not like her in real life at all." Sasha was conceived during the making of "Crazy in Love", and Beyoncé introduced her with the release of her 2008 album I Am... Sasha Fierce. In February 2010, she announced in an interview with Allure magazine that she was comfortable enough with herself to no longer need Sasha Fierce. However, Beyoncé announced in May 2012 that she would bring her back for her Revel Presents: Beyoncé Live shows later that month.

Question: When did Beyoncé introduce Sasha Fierce?
Ans: 2008


Article: The practice of component interface testing can be used to check the handling of data passed between various units, or subsystem components, beyond full integration testing between those units. The data being passed can be considered as "message packets" and the range or data types can be checked, for data generated from one unit, and tested for validity before being passed into another unit. One option for interface testing is to keep a separate log file of data items being passed, often with a timestamp logged to allow analysis of thousands of cases of data passed between units for days or weeks. Tests can include checking the handling of some extreme data values while other interface variables are passed as normal values. Unusual data values in an interface can help explain unexpected performance in the next unit. Component interface testing is a variation of black-box testing, with the focus on the data values beyond just the related actions of a subsystem component.

Question: What is it called to check data passed between units?
Ans: component interface testing


Article: The nature of government under the Angevin monarchs was ill-defined and uncertain. John's predecessors had ruled using the principle of vis et voluntas, or "force and will", taking executive and sometimes arbitrary decisions, often justified on the basis that a king was above the law. Both Henry II and Richard had argued that kings possessed a quality of "divine majesty"; John continued this trend and claimed an "almost imperial status" for himself as ruler. During the 12th century, there were contrary opinions expressed about the nature of kingship, and many contemporary writers believed that monarchs should rule in accordance with the custom and the law, and take counsel of the leading members of the realm. There was as yet no model for what should happen if a king refused to do so. Despite his claim to unique authority within England, John would sometimes justify his actions on the basis that he had taken council with the barons. Modern historians remain divided as to whether John suffered from a case of "royal schizophrenia" in his approach to government, or if his actions merely reflected the complex model of Angevin kingship in the early 13th century.

Question: What principle did John's predecessors use?
Ans: vis et voluntas


Article: German air attacks on the British Isles increased in 1915 and the AA efforts were deemed somewhat ineffective, so a Royal Navy gunnery expert, Admiral Sir Percy Scott, was appointed to make improvements, particularly an integrated AA defence for London. The air defences were expanded with more RNVR AA guns, 75 mm and 3-inch, the pom-poms being ineffective. The naval 3-inch was also adopted by the army, the QF 3 inch 20 cwt (76 mm), a new field mounting was introduced in 1916. Since most attacks were at night, searchlights were soon used, and acoustic methods of detection and locating were developed. By December 1916 there were 183 AA Sections defending Britain (most with the 3-inch), 74 with the BEF in France and 10 in the Middle East.

Question: How many AA Sections were with the BEF in France during the same time?
Ans:
74
