Problem: Please answer a question about the following article about Central African Republic:
Patassé purged many of the Kolingba elements from the government and Kolingba supporters accused Patassé's government of conducting a "witch hunt" against the Yakoma. A new constitution was approved on 28 December 1994 but had little impact on the country's politics. In 1996–1997, reflecting steadily decreasing public confidence in the government's erratic behaviour, three mutinies against Patassé's administration were accompanied by widespread destruction of property and heightened ethnic tension. During this time (1996) the Peace Corps evacuated all its volunteers to neighboring Cameroon. To date, the Peace Corps has not returned to the Central African Republic. The Bangui Agreements, signed in January 1997, provided for the deployment of an inter-African military mission, to Central African Republic and re-entry of ex-mutineers into the government on 7 April 1997. The inter-African military mission was later replaced by a U.N. peacekeeping force (MINURCA).
When was the new constitution for CAR approved?
A: 28 December 1994

Kenneth Gergen formulated additional classifications, which include the strategic manipulator, the pastiche personality, and the relational self. The strategic manipulator is a person who begins to regard all senses of identity merely as role-playing exercises, and who gradually becomes alienated from his or her social "self". The pastiche personality abandons all aspirations toward a true or "essential" identity, instead viewing social interactions as opportunities to play out, and hence become, the roles they play. Finally, the relational self is a perspective by which persons abandon all sense of exclusive self, and view all sense of identity in terms of social engagement with others. For Gergen, these strategies follow one another in phases, and they are linked to the increase in popularity of postmodern culture and the rise of telecommunications technology.

In what classification is a person who gives up their exclusive sense of self and defines him or herself only in terms of social engagement?
Answer: the relational self


Problem: Since it was quite easy to stack interconnections (wires) inside the embedding matrix, the approach allowed designers to forget completely about the routing of wires (usually a time-consuming operation of PCB design): Anywhere the designer needs a connection, the machine will draw a wire in straight line from one location/pin to another. This led to very short design times (no complex algorithms to use even for high density designs) as well as reduced crosstalk (which is worse when wires run parallel to each other—which almost never happens in Multiwire), though the cost is too high to compete with cheaper PCB technologies when large quantities are needed.
What makes Multiwire impractical to use when large quantities of a board are needed?
The answer is the following: cost


The U.S. Federal Reserve and central banks around the world have taken steps to expand money supplies to avoid the risk of a deflationary spiral, in which lower wages and higher unemployment lead to a self-reinforcing decline in global consumption. In addition, governments have enacted large fiscal stimulus packages, by borrowing and spending to offset the reduction in private sector demand caused by the crisis. The U.S. Federal Reserve's new and expanded liquidity facilities were intended to enable the central bank to fulfill its traditional lender-of-last-resort role during the crisis while mitigating stigma, broadening the set of institutions with access to liquidity, and increasing the flexibility with which institutions could tap such liquidity.
What have governments done to offset the reduction in private sector demand?
enacted large fiscal stimulus packages


Input: Oklahoma
Oklahoma has teams in basketball, football, arena football, baseball, soccer, hockey, and wrestling located in Oklahoma City, Tulsa, Enid, Norman, and Lawton. The Oklahoma City Thunder of the National Basketball Association (NBA) is the state's only major league sports franchise. The state had a team in the Women's National Basketball Association, the Tulsa Shock, from 2010 through 2015, but the team relocated to Dallas–Fort Worth after that season and became the Dallas Wings. Oklahoma supports teams in several minor leagues, including Minor League Baseball at the AAA and AA levels (Oklahoma City Dodgers and Tulsa Drillers, respectively), hockey's ECHL with the Tulsa Oilers, and a number of indoor football leagues. In the last-named sport, the state's most notable team was the Tulsa Talons, which played in the Arena Football League until 2012, when the team was moved to San Antonio. The Oklahoma Defenders replaced the Talons as Tulsa's only professional arena football team, playing the CPIFL. The Oklahoma City Blue, of the NBA Development League, relocated to Oklahoma City from Tulsa in 2014, where they were formerly known as the Tulsa 66ers. Tulsa is the base for the Tulsa Revolution, which plays in the American Indoor Soccer League. Enid and Lawton host professional basketball teams in the USBL and the CBA.

What league is the Thunder in?
Output: National Basketball Association


Problem: Please answer a question about the following article about BeiDou Navigation Satellite System:
Compass-M1 transmits in 3 bands: E2, E5B, and E6. In each frequency band two coherent sub-signals have been detected with a phase shift of 90 degrees (in quadrature). These signal components are further referred to as "I" and "Q". The "I" components have shorter codes and are likely to be intended for the open service. The "Q" components have much longer codes, are more interference resistive, and are probably intended for the restricted service. IQ modulation has been the method in both wired and wireless digital modulation since morsetting carrier signal 100 years ago.
What is the phase shift of the sub-signals detected in each frequency band used by  Compass-M1?
A:
90 degrees (in quadrature)
