Interstate 26 begins in downtown Charleston, with exits to the Septima Clark Expressway, the Arthur Ravenel, Jr. Bridge and Meeting Street. Heading northwest, it connects the city to North Charleston, the Charleston International Airport, Interstate 95, and Columbia. The Arthur Ravenel, Jr. Bridge and Septima Clark Expressway are part of U.S. Highway 17, which travels east-west through the cities of Charleston and Mount Pleasant. The Mark Clark Expressway, or Interstate 526, is the bypass around the city and begins and ends at U.S. Highway 17. U.S. Highway 52 is Meeting Street and its spur is East Bay Street, which becomes Morrison Drive after leaving the east side. This highway merges with King Street in the city's Neck area (industrial district). U.S. Highway 78 is King Street in the downtown area, eventually merging with Meeting Street.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Interstate 562 begins and ends at what Highway?
Ah, so.. unanswerable

In an effort to conserve water, Tucson is recharging groundwater supplies by running part of its share of CAP water into various open portions of local rivers to seep into their aquifer. Additional study is scheduled to determine the amount of water that is lost through evaporation from the open areas, especially during the summer. The City of Tucson already provides reclaimed water to its inhabitants, but it is only used for "applications such as irrigation, dust control, and industrial uses." These resources have been in place for more than 27 years, and deliver to over 900 locations.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What does Tucson use reclaimed water for?
Ah, so.. irrigation, dust control, and industrial uses

With the collapse of Roman rule in the early 5th century, London ceased to be a capital and the walled city of Londinium was effectively abandoned, although Roman civilisation continued in the St Martin-in-the-Fields area until around 450. From around 500, an Anglo-Saxon settlement known as Lundenwic developed in the same area, slightly to the west of the old Roman city. By about 680, it had revived sufficiently to become a major port, although there is little evidence of large-scale production of goods. From the 820s the town declined because of repeated Viking invasions. There are three recorded Viking assaults on London; two of which were successful in 851 and 886 AD, although they were defeated during the attack of 994 AD.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): By the late 7th century, what was a main function of Lundenwic?
Ah, so..
a major port
