QUES: Central station electricity can often be generated with higher efficiency than a mobile engine/generator. While the efficiency of power plant generation and diesel locomotive generation are roughly the same in the nominal regime, diesel motors decrease in efficiency in non-nominal regimes at low power while if an electric power plant needs to generate less power it will shut down its least efficient generators, thereby increasing efficiency. The electric train can save energy (as compared to diesel) by regenerative braking and by not needing to consume energy by idling as diesel locomotives do when stopped or coasting. However, electric rolling stock may run cooling blowers when stopped or coasting, thus consuming energy.

Which type of train continues to use energy while coasting or being stopped?
What is the answer?
ANS: diesel
QUES: All assets of the Arena Football League were put up for auction. On November 11, 2009, the new league announced its intention to purchase the entire assets of the former AFL; the assets included the team names and logos of all but one of the former AFL and af2 teams. The lone exception was that of the Dallas Desperados; Desperados owner Jerry Jones had purposely designed the Desperados' properties around those of the Dallas Cowboys, making the two inseparable. The auction occurred on November 25, 2009. The assets were awarded to Arena Football 1 on December 7, 2009, with a winning bid of $6.1 million.

Who owned the Dallas Desperados?
What is the answer?
ANS: Jerry Jones
QUES: To pay for his military campaigns and colonial expansion, Emperor Wu nationalized several private industries. He created central government monopolies administered largely by former merchants. These monopolies included salt, iron, and liquor production, as well as bronze-coin currency. The liquor monopoly lasted only from 98 to 81 BC, and the salt and iron monopolies were eventually abolished in early Eastern Han. The issuing of coinage remained a central government monopoly throughout the rest of the Han dynasty. The government monopolies were eventually repealed when a political faction known as the Reformists gained greater influence in the court. The Reformists opposed the Modernist faction that had dominated court politics in Emperor Wu's reign and during the subsequent regency of Huo Guang (d. 68 BC). The Modernists argued for an aggressive and expansionary foreign policy supported by revenues from heavy government intervention in the private economy. The Reformists, however, overturned these policies, favoring a cautious, non-expansionary approach to foreign policy, frugal budget reform, and lower tax-rates imposed on private entrepreneurs.

Who made up the bulk of the administrators of the new government monopolies?
What is the answer?
ANS:
former merchants
