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: Why did the Kievan state prosper?

Output: abundant supply of furs, beeswax, honey, and slaves for export

Input: Article: The Ottoman legal system accepted the religious law over its subjects. At the same time the Qanun (or Kanun), a secular legal system, co-existed with religious law or Sharia. The Ottoman Empire was always organized around a system of local jurisprudence. Legal administration in the Ottoman Empire was part of a larger scheme of balancing central and local authority. Ottoman power revolved crucially around the administration of the rights to land, which gave a space for the local authority to develop the needs of the local millet. The jurisdictional complexity of the Ottoman Empire was aimed to permit the integration of culturally and religiously different groups. The Ottoman system had three court systems: one for Muslims, one for non-Muslims, involving appointed Jews and Christians ruling over their respective religious communities, and the "trade court". The entire system was regulated from above by means of the administrative Qanun, i.e. laws, a system based upon the Turkic Yassa and Tore, which were developed in the pre-Islamic era.[citation needed]

Now answer this question: What did the Ottoman Empire attempt to balance in its legal policies?

Output: central and local authority
