QUES: However, performance enhancements cannot be generalized as the benefits and limitations of the system are dependent on many factors. One problem is that the system is subject to gaming. Sometimes, one person enters the destination for a large group of people going to the same floor. The dispatching algorithm is usually unable to completely cater for the variation, and latecomers may find the elevator they are assigned to is already full. Also, occasionally, one person may press the floor multiple times. This is common with up/down buttons when people believe this to be an effective way to hurry elevators. However, this will make the computer think multiple people are waiting and will allocate empty cars to serve this one person.
What is generally unable to support variations in the number of people for a particular destination?

ANS: The dispatching algorithm

QUES: In March 1984, Pioneer introduced the first consumer player with a solid-state laser, the LD-700. It was also the first LD player to load from the front and not the top. One year earlier Hitachi introduced an expensive industrial player with a laser diode, but the player, which had poor picture quality due to an inadequate dropout compensator, was made only in limited quantities. After Pioneer released the LD-700, gas lasers were no longer used in consumer players, despite their advantages, although Philips continued to use gas lasers in their industrial units until 1985.
What was the name of the first solid-state laser consumer LaserDisc player?

ANS: LD-700

QUES: From 1877 to 1878, the area suffered a rash of stagecoach robberies. Most notable, however, were the two holdups committed by masked road-agent William Whitney Brazelton. Brazelton held up two stages in the summer of 1878 near Point of Mountain Station approximately 17 mi (27 km) northwest of Tucson. John Clum, of Tombstone, Arizona fame was one of the passengers. Brazelton was eventually tracked down and killed on Monday August 19, 1878, in a mesquite bosque along the Santa Cruz River 3 miles (5 km) south of Tucson by Pima County Sheriff Charles A. Shibell and his citizen's posse. Brazelton had been suspected of highway robbery not only in the Tucson area, but also in the Prescott region and Silver City, New Mexico area as well. Brazelton's crimes prompted John J. Valentine, Sr. of Wells, Fargo & Co. to send special agent and future Pima County sheriff Bob Paul to investigate. Fort Lowell, then east of Tucson, was established to help protect settlers from Apache attacks. In 1882, Frank Stilwell was implicated in the murder of Morgan Earp by Cowboy Pete Spence's wife, Marietta, at the coroner's inquest on Morgan Earp's shooting. The coroner's jury concluded that Spence, Stilwell, Frederick Bode, and Florentino "Indian Charlie" Cruz were the prime suspects in the assassination of Morgan Earp. :250 Deputy U.S. Marshal Wyatt Earp gathered a few trusted friends and accompanied Virgil Earp and his family as they traveled to Benson for a train ride to California. They found Stilwell lying in wait for Virgil in the Tucson station and killed him on the tracks. After killing Stilwell, Wyatt deputized others and rode on a vendetta, killing three more cowboys over the next few days before leaving the state.
When was Brazelton killed?

ANS: August 19, 1878

QUES: Launched worldwide across 2005–2006, the Xbox 360 was initially in short supply in many regions, including North America and Europe. The earliest versions of the console suffered from a high failure rate, indicated by the so-called "Red Ring of Death", necessitating an extension of the device's warranty period. Microsoft released two redesigned models of the console: the Xbox 360 S in 2010, and the Xbox 360 E in 2013. As of June 2014, 84 million Xbox 360 consoles have been sold worldwide, making it the sixth-highest-selling video game console in history, and the highest-selling console made by an American company. Although not the best-selling console of its generation, the Xbox 360 was deemed by TechRadar to be the most influential through its emphasis on digital media distribution and multiplayer gaming on Xbox Live. The Xbox 360's successor, the Xbox One, was released on November 22, 2013. Microsoft has stated they plan to support the Xbox 360 until 2016. The Xbox One is also backwards compatible with the Xbox 360.
As of June 2014, how many 360s across all SKUs have been sold worldwide?
