input question: Extract the answer to the question from the following context. Question: How did the Danish benefit? Context: The Vikings established Danelaw over much of the eastern and northern part of England with its boundary roughly stretching from London to Chester. It was an area of political and geographical control imposed by the Viking incursions which was formally agreed to by the Danish warlord, Guthrum and west-Saxon king, Alfred the Great in 886 AD. The Anglo-Saxon Chronicle recorded that London was "refounded" by Alfred the Great in 886. Archaeological research shows that this involved abandonment of Lundenwic and a revival of life and trade within the old Roman walls. London then grew slowly until about 950, after which activity increased dramatically.???

input question: Extract the answer to the question from the following context. Question: What type of water is NOT used to replenish the groundwater? Context: An urban runoff facility (SMURFF), the first of its kind in the US, catches and treats 3.5 million US gallons (13,000 m3) of water each week that would otherwise flow into the bay via storm-drains and sells it back to end-users within the city for reuse as gray-water, while bio-swales throughout the city allow rainwater to percolate into and replenish the groundwater supply. The groundwater supply in turn plays an important role in the city's Sustainable Water Master Plan, whereby Santa Monica has set a goal of attaining 100% water independence by 2020. The city has numerous programs designed to promote water conservation among residents, including a rebate of $1.50 per square foot for those who convert water intensive lawns to more local drought-tolerant gardens that require less water.???
output answer: gray-water
