Input: Sumer
Sumerian cities during the Uruk period were probably theocratic and were most likely headed by a priest-king (ensi), assisted by a council of elders, including both men and women. It is quite possible that the later Sumerian pantheon was modeled upon this political structure. There was little evidence of organized warfare or professional soldiers during the Uruk period, and towns were generally unwalled. During this period Uruk became the most urbanized city in the world, surpassing for the first time 50,000 inhabitants.

What is an "ensi"?
Output: priest-king

Input: Mali
Mali underwent economic reform, beginning in 1988 by signing agreements with the World Bank and the International Monetary Fund. During 1988 to 1996, Mali's government largely reformed public enterprises. Since the agreement, sixteen enterprises were privatized, 12 partially privatized, and 20 liquidated. In 2005, the Malian government conceded a railroad company to the Savage Corporation. Two major companies, Societé de Telecommunications du Mali (SOTELMA) and the Cotton Ginning Company (CMDT), were expected to be privatized in 2008.

In what year did Mali start economic changes?
Output: 1988

Input: Cardinal (Catholicism)
The cardinal protodeacon, the senior cardinal deacon in order of appointment to the College of Cardinals, has the privilege of announcing a new pope's election and name (once he has been ordained to the Episcopate) from the central balcony at the Basilica of Saint Peter in Vatican City State. In the past, during papal coronations, the proto-deacon also had the honor of bestowing the pallium on the new pope and crowning him with the papal tiara. However, in 1978 Pope John Paul I chose not to be crowned and opted for a simpler papal inauguration ceremony, and his three successors followed that example. As a result, the Cardinal protodeacon's privilege of crowning a new pope has effectively ceased although it could be revived if a future Pope were to restore a coronation ceremony. However, the proto-deacon still has the privilege of bestowing the pallium on a new pope at his papal inauguration. “Acting in the place of the Roman Pontiff, he also confers the pallium upon metropolitan bishops or gives the pallium to their proxies.” The current cardinal proto-deacon is Renato Raffaele Martino.

Who was the first pope who chose not to be crowned?
Output: Pope John Paul I

Input: Antenna (radio)
Efficiency of a transmitting antenna is the ratio of power actually radiated (in all directions) to the power absorbed by the antenna terminals. The power supplied to the antenna terminals which is not radiated is converted into heat. This is usually through loss resistance in the antenna's conductors, but can also be due to dielectric or magnetic core losses in antennas (or antenna systems) using such components. Such loss effectively robs power from the transmitter, requiring a stronger transmitter in order to transmit a signal of a given strength.

What can cause that reaction?
Output:
transmitter
