Input: Article: In central and northern Italy and in Flanders, the rise of towns that were to a degree self-governing stimulated economic growth and created an environment for new types of trade associations. Commercial cities on the shores of the Baltic entered into agreements known as the Hanseatic League, and the Italian Maritime republics such as Venice, Genoa, and Pisa expanded their trade throughout the Mediterranean.[V] Great trading fairs were established and flourished in northern France during the period, allowing Italian and German merchants to trade with each other as well as local merchants. In the late 13th century new land and sea routes to the Far East were pioneered, famously described in The Travels of Marco Polo written by one of the traders, Marco Polo (d. 1324). Besides new trading opportunities, agricultural and technological improvements enabled an increase in crop yields, which in turn allowed the trade networks to expand. Rising trade brought new methods of dealing with money, and gold coinage was again minted in Europe, first in Italy and later in France and other countries. New forms of commercial contracts emerged, allowing risk to be shared among merchants. Accounting methods improved, partly through the use of double-entry bookkeeping; letters of credit also appeared, allowing easy transmission of money.

Now answer this question: Who wrote The Travels of Marco Polo?

Output: Marco Polo

Input: Article: It now became relevant to define the east of the eastern question. In about the middle of the 19th century "Near East" came into use to describe that part of the east closest to Europe. The term "Far East" appeared contemporaneously meaning Japan, China, Korea, Indonesia and Viet Nam; in short, the East Indies. "Near East" applied to what had been mainly known as the Levant, which was in the jurisdiction of the Ottoman Porte, or government. Those who used the term had little choice about its meaning. They could not set foot on most of the shores of the southern and central Mediterranean from the Gulf of Sidra to Albania without permits from the Ottoman Empire.

Now answer this question: What was needed to set foot on most of the shores of the southern and central Mediterranean?

Output: permits from the Ottoman Empire

Input: Article: An early advantage of AC is that the power-wasting resistors used in DC locomotives for speed control were not needed in an AC locomotive: multiple taps on the transformer can supply a range of voltages. Separate low-voltage transformer windings supply lighting and the motors driving auxiliary machinery. More recently, the development of very high power semiconductors has caused the classic "universal" AC/DC motor to be largely replaced with the three-phase induction motor fed by a variable frequency drive, a special inverter that varies both frequency and voltage to control motor speed. These drives can run equally well on DC or AC of any frequency, and many modern electric locomotives are designed to handle different supply voltages and frequencies to simplify cross-border operation.

Now answer this question: What taps can provide lighting supply?

Output:
low-voltage transformer windings
