Problem: 2008 Summer Olympics torch relay:

On April 19, the BBC reported that 1,300 people had gathered outside BBC buildings in Manchester and London, protesting against what they described as Western media bias. Several days earlier, the BBC had published an article entitled "The challenges of reporting in China", responding to earlier criticism. The BBC's Paul Danahar noted that Chinese people were now "able to access the BBC News website for the first time, after years of strict censorship", and that "many were critical of our coverage". He provided readers with a reminder of censorship in China, and added: "People who criticise the media for their coverage in Tibet should acknowledge that we were and still are banned from reporting there." He also quoted critical Chinese responses, and invited readers to comment.

Who commented that Chinese people can look at the BBC news site for the first time?

A: Paul Danahar

Problem: The history of phonology may be traced back to the Ashtadhyayi, the Sanskrit grammar composed by Panini in the 4th century BC. In particular the Shiva Sutras, an auxiliary text to the Ashtadhyayi, introduces what can be considered a list of the phonemes of the Sanskrit language, with a notational system for them that is used throughout the main text, which deals with matters of morphology, syntax and semantics.
What is the name of ancient phenome grammar?

Tsai writes that shortly after the visit by Deshin Shekpa, the Yongle Emperor ordered the construction of a road and of trading posts in the upper reaches of the Yangzi and Mekong Rivers in order to facilitate trade with Tibet in tea, horses, and salt. The trade route passed through Sichuan and crossed Shangri-La County in Yunnan. Wang and Nyima assert that this "tribute-related trade" of the Ming exchanging Chinese tea for Tibetan horseswhile granting Tibetan envoys and Tibetan merchants explicit permission to trade with Han Chinese merchants"furthered the rule of the Ming dynasty court over Tibet". Rossabi and Sperling note that this trade in Tibetan horses for Chinese tea existed long before the Ming. Peter C. Perdue says that Wang Anshi (10211086), realizing that China could not produce enough militarily capable steeds, had also aimed to obtain horses from Inner Asia in exchange for Chinese tea. The Chinese needed horses not only for cavalry but also as draft animals for the army's supply wagons. The Tibetans required Chinese tea not only as a common beverage but also as a religious ceremonial supplement. The Ming government imposed a monopoly on tea production and attempted to regulate this trade with state-supervised markets, but these collapsed in 1449 due to military failures and internal ecological and commercial pressures on the tea-producing regions.
Why did Yongle order the construction?
A: to facilitate trade with Tibet

Context and question: In 1654, Otto von Guericke invented the first vacuum pump and conducted his famous Magdeburg hemispheres experiment, showing that teams of horses could not separate two hemispheres from which the air had been partially evacuated. Robert Boyle improved Guericke's design and with the help of Robert Hooke further developed vacuum pump technology. Thereafter, research into the partial vacuum lapsed until 1850 when August Toepler invented the Toepler Pump and Heinrich Geissler invented the mercury displacement pump in 1855, achieving a partial vacuum of about 10 Pa (0.1 Torr). A number of electrical properties become observable at this vacuum level, which renewed interest in further research.
What was invented by Robert Boyle in 1654?

Question: The city shares a 15-mile (24 km) border with Mexico that includes two border crossings. San Diego hosts the busiest international border crossing in the world, in the San Ysidro neighborhood at the San Ysidro Port of Entry. A second, primarily commercial border crossing operates in the Otay Mesa area; it is the largest commercial crossing on the California-Baja California border and handles the third-highest volume of trucks and dollar value of trade among all United States-Mexico land crossings.
Is there an answer to this question: How long is the border that San Diego shares with Mexico?

Answer: 15-mile (24 km)

Several companies, refusing to pay the licensing fee or having been rejected by Nintendo, found ways to circumvent the console's authentication system. Most of these companies created circuits that used a voltage spike to temporarily disable the 10NES chip in the NES. A few unlicensed games released in Europe and Australia came in the form of a dongle that would be connected to a licensed game, in order to use the licensed game's 10NES chip for authentication. In order to combat unlicensed games, Nintendo of America threatened retailers who sold them with losing their supply of licensed titles. In addition, multiple revisions were made to the NES PCBs to prevent these games from working.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Why didn't the companies circumvent the authentication system?
Ah, so..
