Input: Article: The new Kievan state prospered due to its abundant supply of furs, beeswax, honey, and slaves for export, and because it controlled three main trade routes of Eastern Europe. In the north, Novgorod served as a commercial link between the Baltic Sea and the Volga trade route to the lands of the Volga Bulgars, the Khazars, and across the Caspian Sea as far as Baghdad, providing access to markets and products from Central Asia and the Middle East. Trade from the Baltic also moved south on a network of rivers and short portages along the Dnieper known as the "route from the Varangians to the Greeks," continuing to the Black Sea and on to Constantinople. Kiev was a central outpost along the Dnieper route and a hub with the east-west overland trade route between the Khazars and the Germanic lands of Central Europe. These commercial connections enriched Rus' merchants and princes, funding military forces and the construction of churches, palaces, fortifications, and further towns. Demand for luxury goods fostered production of expensive jewelry and religious wares, allowing their export, and an advanced credit and money-lending system may have also been in place.

Now answer this question: How many trade routes did the Kievan state control?

Output: three

Input: Article: A sound generated on any instrument produces many modes of vibration that occur simultaneously. A listener hears numerous frequencies at once. The vibration with the lowest frequency is called the fundamental frequency; the other frequencies are overtones. Harmonics are an important class of overtones with frequencies that are integer multiples of the fundamental. Whether or not the higher frequencies are integer multiples, they are collectively called the partials, referring to the different parts that make up the total spectrum.

Now answer this question: Integer multiples are collectively called? 

Output: the partials

Input: Article: The status of the town was changed by a later charter of Charles I by at once the formal separation from Portsmouth and the recognition of Southampton as a county, In the charter dated 27 June 1640 the formal title of the town became 'The Town and County of the Town of Southampton'. These charters and Royal Grants, of which there were many, also set out the governance and regulation of the town and port which remained the 'constitution' of the town until the local government organisation of the later Victorian period which from about 1888 saw the setting up of County Councils across England and Wales and including Hampshire County Council who now took on some of the function of Government in Southampton Town. In this regime, The Town and County of the Town of Southampton also became a county borough with shared responsibility for aspects of local government. On 24 February 1964 the status changed again by a Charter of Elizabeth II, creating the City and County of the City of Southampton.

Now answer this question: What year did Southampton receive the charter naming it 'The Town and County of the Town of Southampton'?

Output:
1640
