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

[EX Q]: Seattle's economy is driven by a mix of older industrial companies, and "new economy" Internet and technology companies, service, design and clean technology companies. The city's gross metropolitan product was $231 billion in 2010, making it the 11th largest metropolitan economy in the United States. The Port of Seattle, which also operates Seattle–Tacoma International Airport, is a major gateway for trade with Asia and cruises to Alaska, and is the 8th largest port in the United States in terms of container capacity. Though it was affected by the Great Recession, Seattle has retained a comparatively strong economy, and remains a hotbed for start-up businesses, especially in green building and clean technologies: it was ranked as America's No. 1 "smarter city" based on its government policies and green economy. In February 2010, the city government committed Seattle to becoming North America's first "climate neutral" city, with a goal of reaching zero net per capita greenhouse gas emissions by 2030.
[EX A]: What was Seattle's gross product in 2010?

[EX Q]: Humans would also have derived enormous benefit from the dogs associated with their camps. For instance, dogs would have improved sanitation by cleaning up food scraps. Dogs may have provided warmth, as referred to in the Australian Aboriginal expression "three dog night" (an exceptionally cold night), and they would have alerted the camp to the presence of predators or strangers, using their acute hearing to provide an early warning.
[EX A]:
What did dogs clean up to help with keeping habitations of people clean?
