Problem: Kievan Rus%27:

After the Rus' attack on Constantinople in 860, the Byzantine Patriarch Photius sent missionaries north to convert the Rus' and the Slavs. Prince Rastislav of Moravia had requested the Emperor to provide teachers to interpret the holy scriptures, so in 863 the brothers Cyril and Methodius were sent as missionaries, due to their knowledge of the Slavonic language. The Slavs had no written language, so the brothers devised the Glagolitic alphabet, later developed into Cyrillic, and standardized the language of the Slavs, later known as Old Church Slavonic. They translated portions of the Bible and drafted the first Slavic civil code and other documents, and the language and texts spread throughout Slavic territories, including Kievan Rus'. The mission of Cyril and Methodius served both evangelical and diplomatic purposes, spreading Byzantine cultural influence in support of imperial foreign policy. In 867 the Patriarch announced that the Rus' had accepted a bishop, and in 874 he speaks of an "Archbishop of the Rus'."

Problem: The permanent dissolution of clouds allows unhindered light and thermal radiation. The stability of the atmosphere above the desert prevents any convective overturning, thus making rainfall virtually non-existent. As a consequence, the weather tends to be sunny, dry and stable with a minimal risk of rainfall. Subsiding, diverging, dry air masses associated with subtropical high-pressure systems are extremely unfavorable for the development of convectional showers. The subtropical ridge is the predominate factor that explains the hot desert climate (Koppen climate classification BWh) of this vast region. The lowering of air is the strongest and the most effective over the eastern part of the Great Desert, in the Libyan Desert which is the sunniest, the driest and the most nearly rainless place on the planet rivaling the Atacama Desert, lying in Chile and Peru.
What weather is virtually non-existent?

Answer: rainfall

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The War on Terrorism is a global effort by the governments of several countries (primarily the United States and its principal allies) to neutralize international terrorist groups (primarily Islamic Extremist terrorist groups, including al-Qaeda) and ensure that countries considered by the US and some of its allies to be Rogue Nations no longer support terrorist activities. It has been adopted primarily as a response to the September 11, 2001 attacks on the United States. Since 2001, terrorist motivated attacks upon service members have occurred in Arkansas and Texas.
What term is given to the attempt by the UK and her allies to fight global terrorist groups?

Context and question: It is not clear exactly where collegiate a cappella began. The Rensselyrics of Rensselaer Polytechnic Institute (formerly known as the RPI Glee Club), established in 1873 is perhaps the oldest known collegiate a cappella group.[citation needed] However the longest continuously-singing group is probably The Whiffenpoofs of Yale University, which was formed in 1909 and once included Cole Porter as a member. Collegiate a cappella groups grew throughout the 20th century. Some notable historical groups formed along the way include Princeton University's Tigertones (1946), Colgate University's The Colgate 13 (1942), Dartmouth College's Aires (1946), Cornell University's Cayuga's Waiters (1949) and The Hangovers (1968), the University of Maine Maine Steiners (1958), the Columbia University Kingsmen (1949), the Jabberwocks of Brown University (1949), and the University of Rochester YellowJackets (1956). All-women a cappella groups followed shortly, frequently as a parody of the men's groups: the Smiffenpoofs of Smith College (1936), The Shwiffs of Connecticut College (The She-Whiffenpoofs, 1944), and The Chattertocks of Brown University (1951). A cappella groups exploded in popularity beginning in the 1990s, fueled in part by a change in style popularized by the Tufts University Beelzebubs and the Boston University Dear Abbeys. The new style used voices to emulate modern rock instruments, including vocal percussion/"beatboxing". Some larger universities now have multiple groups. Groups often join one another in on-campus concerts, such as the Georgetown Chimes' Cherry Tree Massacre, a 3-weekend a cappella festival held each February since 1975, where over a hundred collegiate groups have appeared, as well as International Quartet Champions The Boston Common and the contemporary commercial a cappella group Rockapella. Co-ed groups have produced many up-and-coming and major artists, including John Legend, an alumnus of the Counterparts at the University of Pennsylvania, and Sara Bareilles, an alumna of Awaken A Cappella at University of California, Los Angeles. Mira Sorvino is an alumna of the Harvard-Radcliffe Veritones of Harvard College where she had the solo on Only You by Yaz.

Question: The franchise was first created in 1997 as a series of virtual pets, akin toand influenced in style bythe contemporary Tamagotchi or nano Giga Pet toys. The creatures were first designed to look cute and iconic even on the devices' small screens; later developments had them created with a harder-edged style influenced by American comics. The franchise gained momentum with its first anime incarnation, Digimon Adventure, and an early video game, Digimon World, both released in 1999. Several seasons of the anime and films based on them have aired, and the video game series has expanded into genres such as role-playing, racing, fighting, and MMORPGs. Other media forms have also been released.
Is there an answer to this question: In what year was the Digimon video game released?

Answer: 1999

Finally, in the 1990s, Internet Protocol-based videoconferencing became possible, and more efficient video compression technologies were developed, permitting desktop, or personal computer (PC)-based videoconferencing. In 1992 CU-SeeMe was developed at Cornell by Tim Dorcey et al. In 1995 the first public videoconference between North America and Africa took place, linking a technofair in San Francisco with a techno-rave and cyberdeli in Cape Town. At the Winter Olympics opening ceremony in Nagano, Japan, Seiji Ozawa conducted the Ode to Joy from Beethoven's Ninth Symphony simultaneously across five continents in near-real time.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did Nagano Japan take part in the first public video-conference linking two continents?
Ah, so..
