Article: Observing that face-to-face communication of the type that online videos convey has been "fine-tuned by millions of years of evolution", TED curator Chris Anderson referred to several YouTube contributors and asserted that "what Gutenberg did for writing, online video can now do for face-to-face communication". Anderson asserted that it's not far-fetched to say that online video will dramatically accelerate scientific advance, and that video contributors may be about to launch "the biggest learning cycle in human history." In education, for example, the Khan Academy grew from YouTube video tutoring sessions for founder Salman Khan's cousin into what Forbes'  Michael Noer called "the largest school in the world", with technology poised to disrupt how people learn.

Question: What surprising feature does youtube possibly have the chance to revolutionize? 
Ans: face-to-face communication


Here is a question about this article: Kievan Rus' also played an important genealogical role in European politics. Yaroslav the Wise, whose stepmother belonged to the Macedonian dynasty, the greatest one to rule Byzantium, married the only legitimate daughter of the king who Christianized Sweden. His daughters became queens of Hungary, France and Norway, his sons married the daughters of a Polish king and a Byzantine emperor (not to mention a niece of the Pope), while his granddaughters were a German Empress and (according to one theory) the queen of Scotland. A grandson married the only daughter of the last Anglo-Saxon king of England. Thus the Rurikids were a well-connected royal family of the time.
What is the answer to this question: Which three countried did Yaroslav's daughters become queens of?
****
So... Hungary, France and Norway


The problem: Answer a question about this article:
However, during this period, major figures and artists in the scene began leaning away from underground aesthetics. In the music press, the increasingly esoteric writing of post-punk publications soon began to alienate their readerships; it is estimated that within several years, NME suffered the loss of half its circulation. Writers like Paul Morley began advocating "overground brightness" instead of the experimental sensibilities promoted in early years. Morley's own musical collaboration with engineer Gary Langan and programmer J. J. Jeczalik, the Art of Noise, would attempt to bring sampled and electronic sounds to the pop mainstream. A variety of more pop-oriented groups, including ABC, the Associates, Adam and the Ants and Bow Wow Wow (the latter two managed by former Sex Pistols manager Malcolm McLaren) emerged in tandem with the development of the New Romantic subcultural scene. Emphasizing glamour, fashion, and escapism in distinction to the experimental seriousness of earlier post-punk groups, the club-oriented scene drew some suspicion from denizens of the movement.
Many of the big players in the post-punk scene began leaning away from what as time progressed?
****
The answer: underground aesthetics


Problem: Please answer a question about the following article about Gymnastics:
By 1954, Olympic Games apparatus and events for both men and women had been standardized in modern format, and uniform grading structures (including a point system from 1 to 15) had been agreed upon. At this time, Soviet gymnasts astounded the world with highly disciplined and difficult performances, setting a precedent that continues. The new medium of television has helped publicize and initiate a modern age of gymnastics. Both men's and women's gymnastics now attract considerable international interest, and excellent gymnasts can be found on every continent. Nadia Comăneci received the first perfect score, at the 1976 Summer Olympics held in Montreal, Canada. She was coached in Romania by coach, (Hungarian ethnicity), Béla Károlyi. Comaneci scored four of her perfect tens on the uneven bars, two on the balance beam and one in the floor exercise. Even with Nadia's perfect scores, the Romanians lost the gold medal to the Soviet Union. Nevertheless, Comaneci became an Olympic icon.
What year and where was the first perfect score given?
A: 1976 Summer Olympics held in Montreal, Canada


Question: Read this and answer the question

After the decline of Aksum, the Eritrean highlands were under the domain of Bahr Negash ruled by the Bahr Negus. The area was then known as Ma'ikele Bahr ("between the seas/rivers," i.e. the land between the Red Sea and the Mereb river). It was later renamed under Emperor Zara Yaqob as the domain of the Bahr Negash, the Medri Bahri ("Sea land" in Tingrinya, although it included some areas like Shire on the other side of the Mereb, today in Ethiopia). With its capital at Debarwa, the state's main provinces were Hamasien, Serae and Akele Guzai.

What were the main provinces of Medri Bahri?
Answer: Hamasien, Serae and Akele Guzai


Feynman had a great deal of success teaching Carl, using, for example, discussions about ants and Martians as a device for gaining perspective on problems and issues. He was surprised to learn that the same teaching devices were not useful with Michelle. Mathematics was a common interest for father and son; they both entered the computer field as consultants and were involved in advancing a new method of using multiple computers to solve complex problems—later known as parallel computing. The Jet Propulsion Laboratory retained Feynman as a computational consultant during critical missions. One co-worker characterized Feynman as akin to Don Quixote at his desk, rather than at a computer workstation, ready to do battle with the windmills.
What type of computing did Feynman and his son help develop?
parallel computing
