Article: The War of the Austrian Succession had seen the belligerents aligned on a time-honoured basis. France's traditional enemies, Great Britain and Austria, had coalesced just as they had done against Louis XIV. Prussia, the leading anti-Austrian state in Germany, had been supported by France. Neither group, however, found much reason to be satisfied with its partnership: British subsidies to Austria had produced nothing of much help to the British, while the British military effort had not saved Silesia for Austria. Prussia, having secured Silesia, had come to terms with Austria in disregard of French interests. Even so, France had concluded a defensive alliance with Prussia in 1747, and the maintenance of the Anglo-Austrian alignment after 1748 was deemed essential by the Duke of Newcastle, British secretary of state in the ministry of his brother Henry Pelham. The collapse of that system and the aligning of France with Austria and of Great Britain with Prussia constituted what is known as the "diplomatic revolution" or the "reversal of alliances."

Question: What was the major gain by Great Britain by having Austria as it ally?
Ans: British subsidies to Austria had produced nothing of much help to the British

Article: By 1874, Bell's initial work on the harmonic telegraph had entered a formative stage, with progress made both at his new Boston "laboratory" (a rented facility) and at his family home in Canada a big success.[N 14] While working that summer in Brantford, Bell experimented with a "phonautograph", a pen-like machine that could draw shapes of sound waves on smoked glass by tracing their vibrations. Bell thought it might be possible to generate undulating electrical currents that corresponded to sound waves. Bell also thought that multiple metal reeds tuned to different frequencies like a harp would be able to convert the undulating currents back into sound. But he had no working model to demonstrate the feasibility of these ideas.

Question: What did Bell believe the reeds would turn the signal into?
Ans: sound

Article: A route through Beringia is seen as more likely than the Solutrean hypothesis. Kashani et al. 2012 state that "The similarities in ages and geographical distributions for C4c and the previously analyzed X2a lineage provide support to the scenario of a dual origin for Paleo-Indians. Taking into account that C4c is deeply rooted in the Asian portion of the mtDNA phylogeny and is indubitably of Asian origin, the finding that C4c and X2a are characterized by parallel genetic histories definitively dismisses the controversial hypothesis of an Atlantic glacial entry route into North America."

Question: What is more likely than the Solutrean hypothesis?
Ans: route through Beringia

Article: Patent infringement typically is caused by using or selling a patented invention without permission from the patent holder. The scope of the patented invention or the extent of protection is defined in the claims of the granted patent. There is safe harbor in many jurisdictions to use a patented invention for research. This safe harbor does not exist in the US unless the research is done for purely philosophical purposes, or in order to gather data in order to prepare an application for regulatory approval of a drug. In general, patent infringement cases are handled under civil law (e.g., in the United States) but several jurisdictions incorporate infringement in criminal law also (for example, Argentina, China, France, Japan, Russia, South Korea).

Question: What type of law handles patent infringement cases in Russia?
Ans:
criminal
