Problem: Armenia:

Ter-Petrosyan led Armenia alongside Defense Minister Vazgen Sargsyan through the Nagorno-Karabakh War with neighboring Azerbaijan. The initial post-Soviet years were marred by economic difficulties, which had their roots early in the Karabakh conflict when the Azerbaijani Popular Front managed to pressure the Azerbaijan SSR to instigate a railway and air blockade against Armenia. This move effectively crippled Armenia's economy as 85% of its cargo and goods arrived through rail traffic. In 1993, Turkey joined the blockade against Armenia in support of Azerbaijan.

What percent of Armenias commodities were transported via rail traffic?
---
A: 85%

Problem: After a visit to Brasilia, the French writer Simone de Beauvoir complained that all of its superquadras exuded "the same air of elegant monotony," and other observers have equated the city's large open lawns, plazas, and fields to wastelands. As the city has matured, some of these have gained adornments, and many have been improved by landscaping, giving some observers a sense of "humanized" spaciousness. Although not fully accomplished, the "Brasilia utopia" has produced a city of relatively high quality of life, in which the citizens live in forested areas with sporting and leisure structure (the superquadras) flanked by small commercial areas, bookstores and cafes; the city is famous for its cuisine and efficiency of transit.
What did the citizens complain after visiting Brasilia?

Context and question: The most-commonly accepted theory is that these events were triggered by the onset of an ice age, in the Hirnantian faunal stage that ended the long, stable greenhouse conditions typical of the Ordovician. The ice age was probably not as long-lasting as once thought; study of oxygen isotopes in fossil brachiopods shows that it was probably no longer than 0.5 to 1.5 million years. The event was preceded by a fall in atmospheric carbon dioxide (from 7000ppm to 4400ppm) which selectively affected the shallow seas where most organisms lived. As the southern supercontinent Gondwana drifted over the South Pole, ice caps formed on it. Evidence of these ice caps have been detected in Upper Ordovician rock strata of North Africa and then-adjacent northeastern South America, which were south-polar locations at the time.
What is know believed to have lasted more than 1.5 million years?
Answer: unanswerable

Question: Meetings for worship and study are held at Kingdom Halls, which are typically functional in character, and do not contain religious symbols. Witnesses are assigned to a congregation in whose "territory" they usually reside and attend weekly services they refer to as "meetings" as scheduled by congregation elders. The meetings are largely devoted to study of Watch Tower Society literature and the Bible. The format of the meetings is established by the religion's headquarters, and the subject matter for most meetings is the same worldwide. Congregations meet for two sessions each week comprising five distinct meetings that total about three-and-a-half hours, typically gathering mid-week (three meetings) and on the weekend (two meetings). Prior to 2009, congregations met three times each week; these meetings were condensed, with the intention that members dedicate an evening for "family worship". Gatherings are opened and closed with kingdom songs (hymns) and brief prayers. Twice each year, Witnesses from a number of congregations that form a "circuit" gather for a one-day assembly. Larger groups of congregations meet once a year for a three-day "regional convention", usually at rented stadiums or auditoriums. Their most important and solemn event is the commemoration of the "Lord's Evening Meal", or "Memorial of Christ's Death" on the date of the Jewish Passover.
Is there an answer to this question: How many witnesses are there at each Kingdom Hall?

Answer: unanswerable

Comcast operates multiple cable-only channels (including E! Entertainment Television, the Golf Channel, and NBCSN), over-the-air national broadcast network channels (NBC and Telemundo), the film production studio Universal Pictures, and Universal Parks & Resorts, with a global total of nearly 200 family entertainment locations and attractions in the U.S. and several other countries including U.A.E., South Korea, Russia and China, with several new locations reportedly planned and being developed for future operation. Comcast also has significant holding in digital distribution (thePlatform). In February 2014 the company agreed to merge with Time Warner Cable in an equity swap deal worth $45.2 billion. Under the terms of the agreement Comcast was to acquire 100% of Time Warner Cable. However, on April 24, 2015, Comcast terminated the agreement.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How much is Comcast worth?
Ah, so..
