Q: The Maya writing system (often called hieroglyphs from a superficial resemblance to the Ancient Egyptian writing) was a combination of phonetic symbols and logograms. It is most often classified as a logographic or (more properly) a logosyllabic writing system, in which syllabic signs play a significant role. It is the only pre-Columbian writing system known to represent completely the spoken language of its community. In total, the script has more than one thousand different glyphs although a few are variations of the same sign or meaning and many appear only rarely or are confined to particular localities. At any one time, no more than about five hundred glyphs were in use, some two hundred of which (including variations) had a phonetic or syllabic interpretation.

A: What is the Mayan writing system the only known pre-Columbian one to completely represent this?

Q: During the years 1940-1955, the rate of decline in the U.S. death rate accelerated from 2% per year to 8% per year, then returned to the historical rate of 2% per year. The dramatic decline in the immediate post-war years has been attributed to the rapid development of new treatments and vaccines for infectious disease that occurred during these years. Vaccine development continued to accelerate, with the most notable achievement of the period being Jonas Salk's 1954 development of the polio vaccine under the funding of the non-profit National Foundation for Infantile Paralysis. The vaccine process was never patented, but was instead given to pharmaceutical companies to manufacture as a low-cost generic. In 1960 Maurice Hilleman of Merck Sharp & Dohme identified the SV40 virus, which was later shown to cause tumors in many mammalian species. It was later determined that SV40 was present as a contaminant in polio vaccine lots that had been administered to 90% of the children in the United States. The contamination appears to have originated both in the original cell stock and in monkey tissue used for production. In 2004 the United States Cancer Institute announced that it had concluded that SV40 is not associated with cancer in people.

A: When was the Polio vaccine created?

Q: The fire service, known as the Barun Yantra Karyalaya, opened its first station in Kathmandu in 1937 with a single vehicle. An iron tower was erected to monitor the city and watch for fire. As a precautionary measure, firemen were sent to the areas which were designated as accident-prone areas. In 1944, the fire service was extended to the neighboring cities of Lalitpur and Bhaktapur. In 1966, a fire service was established in Kathmandu airport. In 1975, a West German government donation added seven fire engines to Kathmandu's fire service. The fire service in the city is also overlooked by an international non-governmental organization, the Firefighters Volunteer Association of Nepal (FAN), which was established in 2000 with the purpose of raising public awareness about fire and improving safety.

What is Kathmandu's fire department called?
