[Q]: Passage: The war had removed Bermuda's primary trading partners, the American colonies, from the empire, and dealt a harsh blow to Bermuda's merchant shipping trade. This also suffered due to the deforestation of Bermuda, as well as the advent of metal ships and steam propulsion, for which it did not have raw materials. During the course of the following War of 1812, the primary market for Bermuda's salt disappeared as the Americans developed their own sources. Control of the Turks had passed to the Bahamas in 1819.
[A]: What was the primary market for Bermuda following the War of 1812?


[Q]: Passage: Greece was accused of trying to cover up the extent of its massive budget deficit in the wake of the global financial crisis. The allegation was prompted by the massive revision of the 2009 budget deficit forecast by the new PASOK government elected in October 2009, from "6–8%" (estimated by the previous New Democracy government) to 12.7% (later revised to 15.7%). However, the accuracy of the revised figures has also been questioned, and in February 2012 the Hellenic Parliament voted in favor of an official investigation following accusations by a former member of the Hellenic Statistical Authority that the deficit had been artificially inflated in order to justify harsher austerity measures.
[A]:
What was Greece accused of being transparent about?
