Problem: In March 1971, the residential office of an FBI agent in Media, Pennsylvania was burglarized by a group calling itself the Citizens' Commission to Investigate the FBI. Numerous files were taken and distributed to a range of newspapers, including The Harvard Crimson. The files detailed the FBI's extensive COINTELPRO program, which included investigations into lives of ordinary citizens—including a black student group at a Pennsylvania military college and the daughter of Congressman Henry Reuss of Wisconsin. The country was "jolted" by the revelations, which included assassinations of political activists, and the actions were denounced by members of Congress, including House Majority Leader Hale Boggs. The phones of some members of Congress, including Boggs, had allegedly been tapped.
What member of Congress expressed support for the actions of the FBI?

Answer: unanswerable


Problem: Subtractive methods remove copper from an entirely copper-coated board to leave only the desired copper pattern. In additive methods the pattern is electroplated onto a bare substrate using a complex process. The advantage of the additive method is that less material is needed and less waste is produced. In the full additive process the bare laminate is covered with a photosensitive film which is imaged (exposed to light through a mask and then developed which removes the unexposed film). The exposed areas are sensitized in a chemical bath, usually containing palladium and similar to that used for through hole plating which makes the exposed area capable of bonding metal ions. The laminate is then plated with copper in the sensitized areas. When the mask is stripped, the PCB is finished.
In subtractive methods, what metal covers the board and is then partially removed?

Answer: copper


Problem: The 2011 census recorded that 2,998,264 people or 36.7% of London's population are foreign-born making London the city with the second largest immigrant population, behind New York City, in terms of absolute numbers. The table to the right shows the most common countries of birth of London residents. Note that some of the German-born population, in 18th position, are British citizens from birth born to parents serving in the British Armed Forces in Germany. With increasing industrialisation, London's population grew rapidly throughout the 19th and early 20th centuries, and it was for some time in the late 19th and early 20th centuries the most populous city in the world. Its population peaked at 8,615,245 in 1939 immediately before the outbreak of the Second World War, but had declined to 7,192,091 at the 2001 Census. However, the population then grew by just over a million between the 2001 and 2011 Censuses, to reach 8,173,941 in the latter enumeration.
Many German-born Londoners were British citizens by birth due to what?
---
Answer:
parents serving in the British Armed Forces in Germany
