Problem: Anti-aircraft warfare:

In some countries, such as Britain and Germany during the Second World War, the Soviet Union and NATO's Allied Command Europe, ground based air defence and air defence aircraft have been under integrated command and control. However, while overall air defence may be for homeland defence including military facilities, forces in the field, wherever they are, invariably deploy their own air defence capability if there is an air threat. A surface-based air defence capability can also be deployed offensively to deny the use of airspace to an opponent.

What can be deployed as an offensive measure to refuse airspace use to an opponent?
---
A: A surface-based air defence capability

Problem: Hoover began using wiretapping in the 1920s during Prohibition to arrest bootleggers. In the 1927 case Olmstead v. United States, in which a bootlegger was caught through telephone tapping, the United States Supreme Court ruled that FBI wiretaps did not violate the Fourth Amendment as unlawful search and seizure, as long as the FBI did not break into a person's home to complete the tapping. After Prohibition's repeal, Congress passed the Communications Act of 1934, which outlawed non-consensual phone tapping, but allowed bugging. In the 1939 case Nardone v. United States, the court ruled that due to the 1934 law, evidence the FBI obtained by phone tapping was inadmissible in court. After the 1967 case Katz v. United States overturned the 1927 case that had allowed bugging, Congress passed the Omnibus Crime Control Act, allowing public authorities to tap telephones during investigations as long as they obtain a warrant beforehand.
What tool did Hoover use to find bootleggers?

Context and question: Multi-layer printed circuit boards have trace layers inside the board. This is achieved by laminating a stack of materials in a press by applying pressure and heat for a period of time. This results in an inseparable one piece product. For example, a four-layer PCB can be fabricated by starting from a two-sided copper-clad laminate, etch the circuitry on both sides, then laminate to the top and bottom pre-preg and copper foil. It is then drilled, plated, and etched again to get traces on top and bottom layers.
A five-layer PCB can be fabricated how?
Answer: unanswerable

Question: Emotions involve different components, such as subjective experience, cognitive processes, expressive behavior, psychophysiological changes, and instrumental behavior. At one time, academics attempted to identify the emotion with one of the components: William James with a subjective experience, behaviorists with instrumental behavior, psychophysiologists with physiological changes, and so on. More recently, emotion is said to consist of all the components. The different components of emotion are categorized somewhat differently depending on the academic discipline. In psychology and philosophy, emotion typically includes a subjective, conscious experience characterized primarily by psychophysiological expressions, biological reactions, and mental states. A similar multicomponential description of emotion is found in sociology. For example, Peggy Thoits described emotions as involving physiological components, cultural or emotional labels (e.g., anger, surprise etc.), expressive body actions, and the appraisal of situations and contexts.
Is there an answer to this question: Along with subjective experience, cognitive processes, expressive behavior and psychophysiological changes, what is another notable unemotional component?

Answer: unanswerable

Problem: Eton College:

As with other public schools, a scheme was devised towards the end of the 19th century to familiarize privileged schoolboys with social conditions in deprived areas. The project of establishing an 'Eton Mission' in the crowded district of Hackney Wick in east London was started at the beginning of 1880, and lasted until 1971 when it was decided that a more local project (at Dorney) would be more realistic. However over the years much money was raised for the Eton Mission, a fine church by G. F. Bodley was erected, many Etonians visited, and stimulated among other things the Eton Manor Boys' Club, a notable rowing club which has survived the Mission itself, and the 59 Club for motorcyclists.

Which club at Eaton is for motorcyclists?
---
A:
59 Club
