Problem: Muammar Gaddafi:

In the aftermath of the 1986 U.S. attack, the army was purged of perceived disloyal elements, and in 1988, Gaddafi announced the creation of a popular militia to replace the army and police. In 1987, Libya began production of mustard gas at a facility in Rabta, although publicly denying it was stockpiling chemical weapons, and unsuccessfully attempted to develop nuclear weapons. The period also saw a growth in domestic Islamist opposition, formulated into groups like the Muslim Brotherhood and the Libyan Islamic Fighting Group. A number of assassination attempts against Gaddafi were foiled, and in turn, 1989 saw the security forces raid mosques believed to be centres of counter-revolutionary preaching. In October 1993, elements of the increasingly marginalised army initiated a failed coup in Misrata, while in September 1995, Islamists launched an insurgency in Benghazi, and in July 1996 an anti-Gaddafist football riot broke out in Tripoli. The Revolutionary Committees experienced a resurgence to combat these Islamists.

What chemical weapon did Libya start making in 1987?

A: mustard gas

Problem: Energy production in Greece is dominated by the Public Power Corporation (known mostly by its acronym , or in English DEI). In 2009 DEI supplied for 85.6% of all energy demand in Greece, while the number fell to 77.3% in 2010. Almost half (48%) of DEI's power output is generated using lignite, a drop from the 51.6% in 2009. Another 12% comes from Hydroelectric power plants and another 20% from natural gas. Between 2009 and 2010, independent companies' energy production increased by 56%, from 2,709 Gigawatt hour in 2009 to 4,232 GWh in 2010.
What percentage did independent companies' energy production decrease between 2007 and 2010?

In 1971, Tito was re-elected as President of Yugoslavia by the Federal Assembly for the sixth time. In his speech before the Federal Assembly he introduced 20 sweeping constitutional amendments that would provide an updated framework on which the country would be based. The amendments provided for a collective presidency, a 22-member body consisting of elected representatives from six republics and two autonomous provinces. The body would have a single chairman of the presidency and chairmanship would rotate among six republics. When the Federal Assembly fails to agree on legislation, the collective presidency would have the power to rule by decree. Amendments also provided for stronger cabinet with considerable power to initiate and pursue legislature independently from the Communist Party. Dzemal Bijedic was chosen as the Premier. The new amendments aimed to decentralize the country by granting greater autonomy to republics and provinces. The federal government would retain authority only over foreign affairs, defense, internal security, monetary affairs, free trade within Yugoslavia, and development loans to poorer regions. Control of education, healthcare, and housing would be exercised entirely by the governments of the republics and the autonomous provinces.
What branch of the Yugoslav government would retain control over foreign affairs, defense and internal security?
A: federal

Context and question: With $18.8 million spent in 2013, Comcast has the seventh largest lobbying budget of any individual company or organization in the United States. Comcast employs multiple former US Congressmen as lobbyists. The National Cable & Telecommunications Association, which has multiple Comcast executives on its board, also represents Comcast and other cable companies as the fifth largest lobbying organization in the United States, spending $19.8 million in 2013. Comcast was among the top backers of Barack Obama's presidential runs, with Comcast vice president David Cohen raising over $2.2 million from 2007 to 2012. Cohen has been described by many sources as influential in the US government, though he is no longer a registered lobbyist, as the time he spends lobbying falls short of the 20% which requires official registration. Comcast's PAC, the Comcast Corporation and NBCUniversal Political Action Committee, is the among the largest PACs in the US, raising about $3.7 million from 2011-2012 for the campaigns of various candidates for office in the United States Federal Government. Comcast is also a major backer of the National Cable and Telecommunications Association Political Action Committee, which raised $2.6 million from 2011-2012. Comcast spent the most money of any organization in support of the Stop Online Piracy and PROTECT IP bills, spending roughly $5 million to lobby for their passage.
What bills has Comcast opposed?

Part of the phonological study of a language therefore involves looking at data (phonetic transcriptions of the speech of native speakers) and trying to deduce what the underlying phonemes are and what the sound inventory of the language is. The presence or absence of minimal pairs, as mentioned above, is a frequently used criterion for deciding whether two sounds should be assigned to the same phoneme. However, other considerations often need to be taken into account as well.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What kind of speaker data does studying a language phonologically involve examining?
Ah, so..
native
