QUES: Throughout history there have been a series of lingua francas in the area to allow for better communication. The dialects spoken in Hangzhou, Shaoxing, and Ningbo have taken on this role historically. Since the founding of the People's Republic of China in 1949, Mandarin, which is not mutually intelligible with any of the local dialects, has been promoted as the standard language of communication throughout China. As a result, most of the population now can, to some degree, speak and comprehend Mandarin and can code-switch when necessary. A majority of the population educated since 1978 can speak Mandarin. Urban residents tend to be more fluent in Mandarin than rural people. Nevertheless, a Zhejiang accent is detectable in almost everyone from the area communicating in Mandarin, and the home dialect remains an important part of the everyday lives and cultural identities of most Zhejiang residents.

What has been promoted as the standard language of communication throughout China since 1949?
What is the answer?
ANS: Mandarin


QUES: One of the first demonstrations of the ability for telecommunications to help sign language users communicate with each other occurred when AT&T's videophone (trademarked as the "Picturephone") was introduced to the public at the 1964 New York World's Fair –two deaf users were able to communicate freely with each other between the fair and another city. Various universities and other organizations, including British Telecom's Martlesham facility, have also conducted extensive research on signing via videotelephony. The use of sign language via videotelephony was hampered for many years due to the difficulty of its use over slow analogue copper phone lines, coupled with the high cost of better quality ISDN (data) phone lines. Those factors largely disappeared with the introduction of more efficient video codecs and the advent of lower cost high-speed ISDN data and IP (Internet) services in the 1990s.
What was introduced to make extensive research easier over video telephony?

ANS: unanswerable


On 3 December, Chopin complained about his bad health and the incompetence of the doctors in Majorca: "Three doctors have visited me ... The first said I was dead; the second said I was dying; and the third said I was about to die." He also had problems having his Pleyel piano sent to him. It finally arrived from Paris in December. Chopin wrote to Pleyel in January 1839: "I am sending you my Preludes [(Op. 28)]. I finished them on your little piano, which arrived in the best possible condition in spite of the sea, the bad weather and the Palma customs." Chopin was also able to undertake work on his Ballade No. 2, Op. 38; two Polonaises, Op. 40; and the Scherzo No. 3, Op. 39.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did Frédéric have trouble playing as a result of his growing illness?
Ah, so.. piano

QUES: The birthplace of IBM, Endicott, suffered pollution for decades, however. IBM used liquid cleaning agents in circuit board assembly operation for more than two decades, and six spills and leaks were recorded, including one leak in 1979 of 4,100 gallons from an underground tank. These left behind volatile organic compounds in the town's soil and aquifer. Traces of volatile organic compounds have been identified in Endicott’s drinking water, but the levels are within regulatory limits. Also, from 1980, IBM has pumped out 78,000 gallons of chemicals, including trichloroethane, freon, benzene and perchloroethene to the air and allegedly caused several cancer cases among the townspeople. IBM Endicott has been identified by the Department of Environmental Conservation as the major source of pollution, though traces of contaminants from a local dry cleaner and other polluters were also found. Remediation and testing are ongoing, however according to city officials, tests show that the water is safe to drink.
How many gallons of freon leaked into the town's soil in 1979?

ANS:
