Since 1973 Plymouth has been supplied water by South West Water. Prior to the 1973 take over it was supplied by Plymouth County Borough Corporation. Before the 19th century two leats were built in order to provide drinking water for the town. They carried water from Dartmoor to Plymouth. A watercourse, known as Plymouth or Drake's Leat, was opened on 24 April 1591 to tap the River Meavy. The Devonport Leat was constructed to carry fresh drinking water to the expanding town of Devonport and its ever growing dockyard. It was fed by three Dartmoor rivers: The West Dart, Cowsic and Blackabrook. It seems to have been carrying water since 1797, but it was officially completed in 1801. It was originally designed to carry water to Devonport town, but has since been shortened and now carries water to Burrator Reservoir, which feeds most of the water supply of Plymouth. Burrator Reservoir is located about 5 miles (8 km) north of the city and was constructed in 1898 and expanded in 1928.
From where did Drake's Leat draw water?
A: River Meavy

It is commonly believed that the earlier a defect is found, the cheaper it is to fix it. The following table shows the cost of fixing the defect depending on the stage it was found. For example, if a problem in the requirements is found only post-release, then it would cost 10100 times more to fix than if it had already been found by the requirements review. With the advent of modern continuous deployment practices and cloud-based services, the cost of re-deployment and maintenance may lessen over time.
Ho many more times would the cost be if the problem is found after the software's release?
A: 10100 times more
