Q: In the 17th century there were many of these independent local bodies levying their own taxes and administering justice. This early form of local government played a role in the development of a political system in the Netherlands that was decentralised and dependent on communal cooperation. Widespread experience with decentralized government was a factor in the formation of the Dutch Republic in the 16th and 17th centuries. The mandate of Rijkswaterstaat , established in 1798 under French rule, was to centralise water control in the Netherlands. Local water boards refused to give up their autonomy however, so Rijkswaterstaat ended up working alongside the local water boards. Today Rijkswaterstaat has responsibility for major water control structures and other infrastructure like motorways. By 1850 there were about 3,500 water boards in the country. In modern times water boards merged as they dealt with joint  interests. Mergers eventually reduced the number to 25 water boards in 2011. The tasks of water boards remain basically unchanged. Having a rich history dating back to the Middle Ages, they are the oldest governing bodies and the oldest democratic institutions in the Netherlands. Dutch water boards have their own coat of arms, a colourful reminder of their importance in Dutch history. The historic buildings that used to house the water boards are another legacy. Called gemeenlandshuis or waterschaphuis, these charming old buildings can be found at the heart of many Dutch towns.
By how many water boards had the countries water boards decreased by from 1850 to 2011?
A: 3475

Q: The war between Russia and Sweden continued after the disaster of Poltava in 1709, though the shattered Swedish continental army could provide very little help. Russia captured Viborg  in 1710 and successfully held it against Swedish attempts to retake the town in 1711. In 1712 the first Russian campaign to capture Finland began under the  command of General Admiral Fyodor Apraksin. Apraksin gathered an army of 15,000 men at Vyborg and started the operation in late August. Swedish General Georg Henrik Lybecker chose not to face the Russians with his 7,500 men in the prepared positions close to Vyborg and instead withdrew west of Kymijoki river using scorched earth tactics. Apraksin's forces reached the river but chose not to cross it and instead withdrew back to Vyborg, likely due to problems in supply. Swedish efforts to maintain their defences were greatly hampered by the drain of manpower by the continental army and various garrisons around the Baltic Sea as well as by the plague outbreak that struck Finland and Sweden]] between 1710-1713, which devastated the land killing, amongst others, over half of the population of Helsingfors .
Which even happened first, the capture of Viborg or the disaster of Poltava?
A: disaster of Poltava in 1709

Q: On 26 August 1643, during the minority of the former chief, "the Estates of the Kingdom passed an Act for the Committees of War in the shires of Scotland", and among the Commissioners for the Sheriffdom of Sutherland and a par of Inverness-shire, occurs the name of "Sir Robert Munro, tutour of Foulles"; and again on 24 July 1644, in a commission for a similar purpose and for the same Sheriffdom is found the name of "Sir Robert Monro, Tutor of Foullis". In 1649, the Scottish Parliament separated from the Sherriffdom of Inverness-shire the "lands eastward of Altnalait, Knockravock and the Royal Burgh of Tain", erected the Sherriffdom of Ross, and appointed the Marquiss of Argyll the Sherriff-Principal. Afterwards the commission was granted to Sir Robert Munro, who had been elected Member of Parliament for Inverness-shire in 1649 and for his own County of Ross after it was separated from the County of Inverness, 1649-50, to be Sheriff-Principal of the County of Ross. In 1651 Robert succeeded to the head of his house, upon the death of his cousin Sir Hector Munro, 2nd Baronet of Foulis who died at just 17 years of age, as already mentioned. Robert took up his residence in Foulis Castle.
