Question: Waterkasteel was a defense in the colony coming under the administration of the Dutch government in what year?
Context: The Dutch East Indies (or Netherlands East-Indies; Dutch: "Nederlands(ch)-Indië" ; Indonesian: "Hindia Belanda" ) was a Dutch colony.  It was formed from the nationalised colonies of the Dutch East India Company, which came under the administration of the Dutch government in 1800. The Netherlands Environmental Assessment Agency (Dutch: "Planbureau voor de Leefomgeving" - abbr.  "PBL") is a Dutch research institute that advises the Dutch government on environmental policy and regional planning issues.  The research fields include sustainable development, energy and climate change, biodiversity, transport, land use, and air quality.  It is one of three applied policy research institutes of the Dutch government, the other two being "Centraal Planbureau" (CPB), and "Sociaal en Cultureel Planbureau" (SCP).  Since November 2015 Hans Mommaas is director of the Netherlands Environmental Assessment Agency. In the context of the law of the Netherlands, the term gedogen (toleration, although "gedogen" does not literally mean "toleration"; one can describe it best as toleration in law) refers to not enforcing certain laws.  The Dutch government tolerates some offences.  Some things like possessing small amounts of cannabis are formally forbidden by law, but the Dutch government abstains from bringing criminal charges against the offenders.  Often these policies are brought about by a tension between treaty obligations and domestic politics.  See policies on cannabis and euthanasia for more information. The Weerbaarheidsafdeling (typically called WA) was the paramilitary arm of the National Socialist Movement in the Netherlands (Dutch: NSB), the fascist political party that collaborated with the German occupiers of the Netherlands during World War II.  The organization, roughly equivalent to the German SA, was founded in 1932 by Anton Mussert, co-founder of the NSB in 1931 and its leader until the end of the war.  Members wore and marched in black uniforms and were thus called "blackshirts".  In 1933 the Dutch government banned the wearing of uniforms (by civilians), and the WA was disbanded in 1935 in order to forestall the Dutch government's banning it.  In 1940, after the German invasion, the WA became openly active again, and more ruthless than before.  They specialized in violent attacks, particularly on the Dutch Jewish population.

He was appointed Lieutenant China, which he held for twenty-one years after which he was made Captain China.  The Dutch Government conferred on him the Gold Star for "Trouw en Verdienste" and with a gold medal for outstanding contributions to them.  Around 1898 he relinquished management of his business interests there, handing them over to the management of his attorney, Mr. Leong Mok On, and moved to Penang where he lived at No. 8, Leith Street.  He was appointed Chinese Vice-Consul to Penang, a position that was taken up by his son-in-law, Mr. Leong Fee, upon his resignation.  He had interests in the Tambun mines in Perak and the Bentong mines near Kuala Lumpur.  He was a member of the Penang Chinese Town Hall committee.

The Dutch government revived the old name that had been used prior to the acquisition by Fortis in 2000 for the newly structured company. The adoption of plug-in electric vehicles in the Netherlands is actively supported by the Dutch government through the exemption of the registration fee and road taxes.  These purchase incentives have been adjusted over time.  Considering the potential of plug-in electric vehicles in the country due to its relative small size and geography, the Dutch government set a target of 15,000 to 20,000 electric vehicles with three or more wheels on the roads in 2015; 200,000 vehicles in 2020; and 1 million vehicles in 2025.  The first government target was achieved in 2013, two years earlier, thanks to the sales peak that occurred at the end of 2013.  The stock of light-duty plug-in electric vehicles registered in the Netherlands achieved the 100,000 unit milestone in November 2016.
