Problem: Josip Broz Tito:

Every year a "Brotherhood and Unity" relay race is organized in Montenegro, Macedonia and Serbia which ends at the "House of Flowers" in Belgrade on May 25 – the final resting place of Tito. At the same time, runners in Slovenia, Croatia and Bosnia and Herzegovina set off for Kumrovec, Tito's birthplace in northern Croatia. The relay is a left-over from Yugoslav times, when young people made a similar yearly trek on foot through Yugoslavia that ended in Belgrade with a massive celebration.

Where is the final resting place of Tito?

A: Belgrade


Problem: A new approach to avoiding overhead wires is taken by the "second generation" tram/streetcar system in Bordeaux, France (entry into service of the first line in December 2003; original system discontinued in 1958) with its APS (alimentation par sol – ground current feed). This involves a third rail which is flush with the surface like the tops of the running rails. The circuit is divided into segments with each segment energized in turn by sensors from the car as it passes over it, the remainder of the third rail remaining "dead". Since each energized segment is completely covered by the lengthy articulated cars, and goes dead before being "uncovered" by the passage of the vehicle, there is no danger to pedestrians. This system has also been adopted in some sections of the new tram systems in Reims, France (opened 2011) and Angers, France (also opened 2011). Proposals are in place for a number of other new services including Dubai, UAE; Barcelona, Spain; Florence, Italy; Marseille, France; Gold Coast, Australia; Washington, D.C., U.S.A.; Brasília, Brazil and Tours, France.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In 1768 Russian-backed Ukrainian Haidamaks, pursuing Polish confederates, entered Balta, an Ottoman-controlled town on the border of Bessarabia in Ukraine, and massacred its citizens and burned the town to the ground. This action provoked the Ottoman Empire into the Russo-Turkish War of 1768–1774. The Treaty of Küçük Kaynarca of 1774 ended the war and provided freedom to worship for the Christian citizens of the Ottoman-controlled provinces of Wallachia and Moldavia. By the late 18th century, a number of defeats in several wars with Russia led some people in the Ottoman Empire to conclude that the reforms of Peter the Great had given the Russians an edge, and the Ottomans would have to keep up with Western technology in order to avoid further defeats.
The Russo-Turkish War resulted in what treaty?
A: Treaty of Küçük Kaynarca


Context and question: For English Dominican mystics, the mystical experience was not expressed just in one moment of the full knowledge of God, but in the journey of, or process of, faith. This then led to an understanding that was directed toward an experiential knowledge of divinity. It is important to understand, however, that for these mystics it was possible to pursue mystical life without the visions and voices that are usually associated with such a relationship with God. They experienced a mystical process that allowed them, in the end, to experience what they had already gained knowledge of through their faith only.
What was not important to English mystics?
Answer: unanswerable


Question: PlayStation 3 launched in North America with 14 titles, with another three being released before the end of 2006. After the first week of sales it was confirmed that Resistance: Fall of Man from Insomniac Games was the top-selling launch game in North America. The game was heavily praised by numerous video game websites, including GameSpot and IGN, both of whom awarded it their PlayStation 3 Game of the Year award for 2006. Some titles missed the launch window and were delayed until early 2007, such as The Elder Scrolls IV: Oblivion, F.E.A.R. and Sonic the Hedgehog. During the Japanese launch, Ridge Racer 7 was the top-selling game, while Mobile Suit Gundam: Crossfire also fared well in sales, both of which were offerings from Namco Bandai Games. PlayStation 3 launched in Europe with 24 titles, including ones that were not offered in North American and Japanese launches, such as Formula One Championship Edition, MotorStorm and Virtua Fighter 5. Resistance: Fall of Man and MotorStorm were the most successful titles of 2007, and both games subsequently received sequels in the form of Resistance 2 and MotorStorm: Pacific Rift.
Is there an answer to this question: What game was heavily criticized by many video game websites?

Answer: unanswerable


Question: Natural uranium consists of three major isotopes: uranium-238 (99.28% natural abundance), uranium-235 (0.71%), and uranium-234 (0.0054%). All three are radioactive, emitting alpha particles, with the exception that all three of these isotopes have small probabilities of undergoing spontaneous fission, rather than alpha emission. There are also five other trace isotopes: uranium-239, which is formed when 238U undergoes spontaneous fission, releasing neutrons that are captured by another 238U atom; uranium-237, which is formed when 238U captures a neutron but emits two more, which then decays to neptunium-237; uranium-233, which is formed in the decay chain of that neptunium-237; and finally, uranium-236 and -240, which appear in the decay chain of primordial plutonium-244. It is also expected that thorium-232 should be able to undergo double beta decay, which would produce uranium-232, but this has not yet been observed experimentally.
Is there an answer to this question: When uranium isotope is formed from the decay of neptunium-237?

Answer:
uranium-233
