input: Please answer the following: I know that the answer to the question "What was the furthest location mentioned that felt the earthquake?" is in "It is also known as the Wenchuan earthquake (Chinese: 汶川大地震; pinyin: Wènchuān dà dìzhèn; literally: "Great Wenchuan earthquake"), after the location of the earthquake's epicenter, Wenchuan County, Sichuan. The epicenter was 80 kilometres (50 mi) west-northwest of Chengdu, the provincial capital, with a focal depth of 19 km (12 mi). The earthquake was also felt in nearby countries and as far away as both Beijing and Shanghai—1,500 km (930 mi) and 1,700 km (1,060 mi) away—where office buildings swayed with the tremor. Strong aftershocks, some exceeding magnitude 6, continued to hit the area even months after the main quake, causing new casualties and damage.". Can you tell me what it is?

Please answer this: I know that the answer to the question "What has two different values?" is in "QED vacuum has interesting and complex properties. In QED vacuum, the electric and magnetic fields have zero average values, but their variances are not zero. As a result, QED vacuum contains vacuum fluctuations (virtual particles that hop into and out of existence), and a finite energy called vacuum energy. Vacuum fluctuations are an essential and ubiquitous part of quantum field theory. Some experimentally verified effects of vacuum fluctuations include spontaneous emission and the Lamb shift. Coulomb's law and the electric potential in vacuum near an electric charge are modified.". Can you tell me what it is?

Answer: electric and magnetic fields


Problem: I know that the answer to the question "Who proposed a fine against Southwest Airlines?" is in "The FAA has been cited as an example of regulatory capture, "in which the airline industry openly dictates to its regulators its governing rules, arranging for not only beneficial regulation, but placing key people to head these regulators." Retired NASA Office of Inspector General Senior Special Agent Joseph Gutheinz, who used to be a Special Agent with the Office of Inspector General for the Department of Transportation and with FAA Security, is one of the most outspoken critics of FAA. Rather than commend the agency for proposing a $10.2 million fine against Southwest Airlines for its failure to conduct mandatory inspections in 2008, he was quoted as saying the following in an Associated Press story: "Penalties against airlines that violate FAA directives should be stiffer. At $25,000 per violation, Gutheinz said, airlines can justify rolling the dice and taking the chance on getting caught. He also said the FAA is often too quick to bend to pressure from airlines and pilots." Other experts have been critical of the constraints and expectations under which the FAA is expected to operate. The dual role of encouraging aerospace travel and regulating aerospace travel are contradictory. For example, to levy a heavy penalty upon an airline for violating an FAA regulation which would impact their ability to continue operating would not be considered encouraging aerospace travel.".

A: the agency


Problem: Given the question: I know that the answer to the question "Which was bigger, Pinkerton or the Army?" is in "In the American Old West, policing was often of very poor quality.[citation needed] The Army often provided some policing alongside poorly resourced sheriffs and temporarily organized posses.[citation needed] Public organizations were supplemented by private contractors, notably the Pinkerton National Detective Agency, which was hired by individuals, businessmen, local governments and the federal government. At its height, the Pinkerton Agency's numbers exceeded those of the United States Army.[citation needed]". Can you tell me what it is?

The answer is:
Pinkerton


input question: I know that the answer to the question "What be subject ot dofferent levels of pressure?" is in "Hydrostatic gauges (such as the mercury column manometer) consist of a vertical column of liquid in a tube whose ends are exposed to different pressures. The column will rise or fall until its weight is in equilibrium with the pressure differential between the two ends of the tube. The simplest design is a closed-end U-shaped tube, one side of which is connected to the region of interest. Any fluid can be used, but mercury is preferred for its high density and low vapour pressure. Simple hydrostatic gauges can measure pressures ranging from 1 torr (100 Pa) to above atmospheric. An important variation is the McLeod gauge which isolates a known volume of vacuum and compresses it to multiply the height variation of the liquid column. The McLeod gauge can measure vacuums as high as 10−6 torr (0.1 mPa), which is the lowest direct measurement of pressure that is possible with current technology. Other vacuum gauges can measure lower pressures, but only indirectly by measurement of other pressure-controlled properties. These indirect measurements must be calibrated via a direct measurement, most commonly a McLeod gauge.". Can you tell me what it is????

input question: I know that the answer to the question "What method did people use to  complain about the book?" is in "One of the first incidents of the book being challenged was in Hanover, Virginia, in 1966: a parent protested that the use of rape as a plot device was immoral. Johnson cites examples of letters to local newspapers, which ranged from amusement to fury; those letters expressing the most outrage, however, complained about Mayella Ewell's attraction to Tom Robinson over the depictions of rape. Upon learning the school administrators were holding hearings to decide the book's appropriateness for the classroom, Harper Lee sent $10 to The Richmond News Leader suggesting it to be used toward the enrollment of "the Hanover County School Board in any first grade of its choice". The National Education Association in 1968 placed the novel second on a list of books receiving the most complaints from private organizations—after Little Black Sambo.".
