In ultra high vacuum systems, some very "odd" leakage paths and outgassing sources must be considered. The water absorption of aluminium and palladium becomes an unacceptable source of outgassing, and even the adsorptivity of hard metals such as stainless steel or titanium must be considered. Some oils and greases will boil off in extreme vacuums. The permeability of the metallic chamber walls may have to be considered, and the grain direction of the metallic flanges should be parallel to the flange face.
What becomes a concern in an ultra high vacuum system regarding aluminum or palladium?
water absorption

Input: Republic of the Congo
In the early 1980s, rapidly rising oil revenues enabled the government to finance large-scale development projects with GDP growth averaging 5% annually, one of the highest rates in Africa. The government has mortgaged a substantial portion of its petroleum earnings, contributing to a shortage of revenues. January 12, 1994 devaluation of Franc Zone currencies by 50% resulted in inflation of 46% in 1994, but inflation has subsided since.

How much inflation did the Congo experience as a result of the devaluation of the Franc?
Output: 46%

Input: Article: The Ministry of Defence is one of the United Kingdom's largest landowners, owning 227,300 hectares of land and foreshore (either freehold or leasehold) at April 2014, which was valued at "about 20 billion". The MoD also has "rights of access" to a further 222,000 hectares. In total, this is about 1.8% of the UK land mass. The total annual cost to support the defence estate is "in excess of 3.3 billion".

Now answer this question: How much is the land owned by the MoD worth?

Output: 20 billion

Article: Pope Sixtus V limited the number of cardinals to 70, comprising six cardinal bishops, 50 cardinal priests, and 14 cardinal deacons. Starting in the pontificate of Pope John XXIII, that limit has been exceeded. At the start of 1971, Pope Paul VI set the number of cardinal electors at a maximum of 120, but set no limit on the number of cardinals generally. He also established a maximum age of eighty years for electors. His action deprived twenty-five living cardinals, including the three living cardinals elevated by Pope Pius XI, of the right to participate in a conclave.[citation needed] Popes can dispense from church laws and have sometimes brought the number of cardinals under the age of 80 to more than 120. Pope Paul VI also increased the number of cardinal bishops by giving that rank to patriarchs of the Eastern Catholic Churches.

Question: What is the maximum age for electors?
Ans: 80

Here is a question about this article: An important idea in the definition of a university is the notion of academic freedom. The first documentary evidence of this comes from early in the life of the first university. The University of Bologna adopted an academic charter, the Constitutio Habita, in 1158 or 1155, which guaranteed the right of a traveling scholar to unhindered passage in the interests of education. Today this is claimed as the origin of "academic freedom". This is now widely recognised internationally - on 18 September 1988, 430 university rectors signed the Magna Charta Universitatum, marking the 900th anniversary of Bologna's foundation. The number of universities signing the Magna Charta Universitatum continues to grow, drawing from all parts of the world.
What is the answer to this question: What charter is said to be the first establishing academic freedom in a university?
****
So... the Constitutio Habita

Article: At the end of the Late Middle Ages, professional actors began to appear in England and Europe. Richard III and Henry VII both maintained small companies of professional actors. Their plays were performed in the Great Hall of a nobleman's residence, often with a raised platform at one end for the audience and a "screen" at the other for the actors. Also important were Mummers' plays, performed during the Christmas season, and court masques. These masques were especially popular during the reign of Henry VIII who had a House of Revels built and an Office of Revels established in 1545.

Question: What did Henry VIII build in 1545 for the benefit of the theatrical arts?
Ans:
House of Revels
