Problem: Gothic architecture:

It was principally the widespread introduction of a single feature, the pointed arch, which was to bring about the change that separates Gothic from Romanesque. The technological change permitted a stylistic change which broke the tradition of massive masonry and solid walls penetrated by small openings, replacing it with a style where light appears to triumph over substance. With its use came the development of many other architectural devices, previously put to the test in scattered buildings and then called into service to meet the structural, aesthetic and ideological needs of the new style. These include the flying buttresses, pinnacles and traceried windows which typify Gothic ecclesiastical architecture. But while pointed arch is so strongly associated with the Gothic style, it was first used in Western architecture in buildings that were in other ways clearly Romanesque, notably Durham Cathedral in the north of England, Monreale Cathedral and Cathedral of Cefalu in Sicily, Autun Cathedral in France.

What is the name of the cathedral in Southern England that first displayed the use of the pointed arch?

Problem: Paper made from wood pulp is not necessarily less durable than a rag paper. The ageing behavior of a paper is determined by its manufacture, not the original source of the fibres. Furthermore, tests sponsored by the Library of Congress prove that all paper is at risk of acid decay, because cellulose itself produces formic, acetic, lactic and oxalic acids.
Who sponsored the tests that show that all papers are not subject to acid decay?

Context and question: Royal assent is the final stage in the legislative process for acts of the Scottish parliament. The process is governed by sections 28, 32, and 33 of the Scotland Act 1998. After a bill has been passed, the Presiding Officer of the Scottish Parliament submits it to the monarch for royal assent after a four-week period, during which the Advocate General for Scotland, the Lord Advocate, the Attorney General or the Secretary of State for Scotland may refer the bill to the Supreme Court of the United Kingdom (prior to 1 October 2009, the Judicial Committee of the Privy Council) for review of its legality. Royal assent is signified by letters patent under the Great Seal of Scotland in the following form which is set out in The Scottish Parliament (Letters Patent and Proclamations) Order 1999 (SI 1999/737) and of which notice is published in the London, Edinburgh, and Belfast Gazettes:

Question: The 2013 season resulted in much as the same the year before. Shortly before the trade deadline, the Cubs traded Matt Garza to the Texas Rangers for Mike Olt, C. J. Edwards, Neil Ramirez, and Justin Grimm. Three days later, the Cubs sent Alfonso Soriano to the New York Yankees for minor leaguer Corey Black. The mid season fire sale led to another last place finish in the NL Central, finishing with a record of 66-96. Although there was a five-game improvement in the record from the year before, Anthony Rizzo and Starlin Castro seemed to take steps backward in their development. On September 30, 2013, Theo Epstein made the decision to fire manager Dale Sveum after just two seasons at the helm of the Cubs. The regression of several young players was thought to be the main focus point, as the front office said Dale would not be judged based on wins and losses. In two seasons as skipper, Sveum finished with a record of 127-197.
Is there an answer to this question: Who did the Cubs send to the New York Yankees for minor leaguer Corey Black?

Answer: Alfonso Soriano

The cuisine of Switzerland is multifaceted. While some dishes such as fondue, raclette or rosti are omnipresent through the country, each region developed its own gastronomy according to the differences of climate and languages. Traditional Swiss cuisine uses ingredients similar to those in other European countries, as well as unique dairy products and cheeses such as Gruyere or Emmental, produced in the valleys of Gruyeres and Emmental. The number of fine-dining establishments is high, particularly in western Switzerland.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What part of Switzerland has a particularly high number of fine-dining establishments?
Ah, so..
western Switzerland
