Problem: Gothic architecture:

On the interior of the building attached shafts often sweep unbroken from floor to ceiling and meet the ribs of the vault, like a tall tree spreading into branches. The verticals are generally repeated in the treatment of the windows and wall surfaces. In many Gothic churches, particularly in France, and in the Perpendicular period of English Gothic architecture, the treatment of vertical elements in gallery and window tracery creates a strongly unifying feature that counteracts the horizontal divisions of the interior structure.

Where are the verticals never repeated in the interior of Gothic buildings?

Problem: Some of the county's secondary schools have specialist school status. Some schools have sixth forms and others transfer their sixth formers to colleges. Several schools can trace their origins back many years, such as The Blue School in Wells and Richard Huish College in Taunton. Others have changed their names over the years such as Beechen Cliff School which was started in 1905 as the City of Bath Boys' School and changed to its present name in 1972 when the grammar school was amalgamated with a local secondary modern school, to form a comprehensive school. Many others were established and built since the Second World War. In 2006, 5,900 pupils in Somerset sat GCSE examinations, with 44.5% achieving 5 grades A-C including English and Maths (compared to 45.8% for England).
What 5 grades A-C percentage to they get at City of Bath Boys' School?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The population geneticist Sewall Wright developed one way of measuring genetic differences between populations known as the Fixation index, which is often abbreviated to FST. This statistic is often used in taxonomy to compare differences between any two given populations by measuring the genetic differences among and between populations for individual genes, or for many genes simultaneously. It is often stated that the fixation index for humans is about 0.15. This translates to an estimated 85% of the variation measured in the overall human population is found within individuals of the same population, and about 15% of the variation occurs between populations. These estimates imply that any two individuals from different populations are almost as likely to be more similar to each other than either is to a member of their own group. Richard Lewontin, who affirmed these ratios, thus concluded neither "race" nor "subspecies" were appropriate or useful ways to describe human populations. However, others have noticed that group variation was relatively similar to the variation observed in other mammalian species.
What was Wright's method known as?
A: the Fixation index

Context and question: Following a tentative agreement on by December 1, on December 3, 2009, the parties announced that Comcast would buy a controlling 51% stake in NBCUniversal for $6.5 billion in cash and $7.3 billion in programming. GE would take over the remaining 49% stake in NBCUniversal, using $5.8 billion to buy out Vivendi's 20% minority stake in NBCUniversal. On January 18, 2011, the FCC approved the deal by a vote of 4 to 1. The sale was completed on January 28, 2011. In late December 2012, Comcast added the NBC peacock symbol to their new logo. On February 12, 2013, Comcast announced an intention to acquire the remaining 49% of General Electric's interest in NBCUniversal, which Comcast completed on March 19, 2013.
On what date was the sale finally completed?
Answer: January 28, 2011

Question: The majority of studies indicate antibiotics do interfere with contraceptive pills, such as clinical studies that suggest the failure rate of contraceptive pills caused by antibiotics is very low (about 1%). In cases where antibacterials have been suggested to affect the efficiency of birth control pills, such as for the broad-spectrum antibacterial rifampicin, these cases may be due to an increase in the activities of hepatic liver enzymes' causing increased breakdown of the pill's active ingredients. Effects on the intestinal flora, which might result in reduced absorption of estrogens in the colon, have also been suggested, but such suggestions have been inconclusive and controversial. Clinicians have recommended that extra contraceptive measures be applied during therapies using antibacterials that are suspected to interact with oral contraceptives.
Is there an answer to this question: What percentage of birth control pill failure is attributed to estrogens?

Answer: unanswerable

Question: Since 1947, Canadian military units have participated in more than 200 operations worldwide, and completed 72 international operations. Canadian soldiers, sailors, and aviators came to be considered world-class professionals through conspicuous service during these conflicts and the country's integral participation in NATO during the Cold War, First Gulf War, Kosovo War, and in United Nations Peacekeeping operations, such as the Suez Crisis, Golan Heights, Cyprus, Croatia, Bosnia, Afghanistan, and Libya. Canada maintained an aircraft carrier from 1957 to 1970 during the Cold War, which never saw combat but participated in patrols during the Cuban Missile Crisis.
Is there an answer to this question: What are some of the wars the Canadian Military was involved in?

Answer:
Cold War, First Gulf War, Kosovo War
