Input: Read this: To create green sparks, fireworks use barium salts, such as barium chlorate, barium nitrate crystals, or barium chloride, also used for green fireplace logs. Copper salts typically burn blue, but cupric chloride (also known as "campfire blue") can also produce green flames. Green pyrotechnic flares can use a mix ratio 75:25 of boron and potassium nitrate. Smoke can be turned green by a mixture: solvent yellow 33, solvent green 3, lactose, magnesium carbonate plus sodium carbonate added to potassium chlorate.
Question: What type of copper salts are used in fireworks?

Output: unanswerable


QUES: In 1663 at the Archbishop of Canterbury's residence, Lambeth Palace, a Gothic hammerbeam roof was built to replace that destroyed when the building was sacked during the English Civil War. Also in the late 17th century, some discrete Gothic details appeared on new construction at Oxford University and Cambridge University, notably on Tom Tower at Christ Church, Oxford, by Christopher Wren. It is not easy to decide whether these instances were Gothic survival or early appearances of Gothic revival.

What is the name of the Archbishop of Canterbury's residence?
What is the answer?
ANS: Lambeth Palace


QUES: The radiation of many antennas shows a pattern of maxima or "lobes" at various angles, separated by "nulls", angles where the radiation falls to zero. This is because the radio waves emitted by different parts of the antenna typically interfere, causing maxima at angles where the radio waves arrive at distant points in phase, and zero radiation at other angles where the radio waves arrive out of phase. In a directional antenna designed to project radio waves in a particular direction, the lobe in that direction is designed larger than the others and is called the "main lobe". The other lobes usually represent unwanted radiation and are called "sidelobes". The axis through the main lobe is called the "principal axis" or "boresight axis".
What do radio waves do that account for maxima or nulls in an antenna pattern?

ANS: interfere


The Supreme Court is the highest court in Ireland. It has authority to interpret the constitution, and strike down laws and activities of the state that it finds to be unconstitutional. It is also the highest authority in the interpretation of the law. Constitutionally it must have authority to interpret the constitution but its further appellate jurisdiction from lower courts is defined by law. The Irish Supreme Court consists of its presiding member, the Chief Justice, and seven other judges. Judges of the Supreme Court are appointed by the President in accordance with the binding advice of the Government. The Supreme Court sits in the Four Courts in Dublin.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Ireland's highest court has the power to determine whether laws are allowed by what document?
Ah, so.. the constitution


Question: In 1966 The Blind Beggar in Whitechapel became infamous as the scene of a murder committed by gangster Ronnie Kray. The Ten Bells is associated with several of the victims of Jack the Ripper. In 1955, Ruth Ellis, the last woman executed in the United Kingdom, shot David Blakely as he emerged from The Magdala in South Hill Park, Hampstead, the bullet holes can still be seen in the walls outside. It is said that Vladimir Lenin and a young Joseph Stalin met in the Crown and Anchor pub (now known as The Crown Tavern) on Clerkenwell Green when the latter was visiting London in 1903.
Try to answer this question if possible: Outside what pub was David Blakely shot?
Answer: The Magdala


Question: One of the first victims was Northern Rock, a medium-sized British bank. The highly leveraged nature of its business led the bank to request security from the Bank of England. This in turn led to investor panic and a bank run in mid-September 2007. Calls by Liberal Democrat Treasury Spokesman Vince Cable to nationalise the institution were initially ignored; in February 2008, however, the British government (having failed to find a private sector buyer) relented, and the bank was taken into public hands. Northern Rock's problems proved to be an early indication of the troubles that would soon befall other banks and financial institutions.
Try to answer this question if possible: When did Northern Rock investors panic and a bank run begin?
Answer:
September 2007
