Input: Antenna (radio)
Maximum power transfer requires matching the impedance of an antenna system (as seen looking into the transmission line) to the complex conjugate of the impedance of the receiver or transmitter. In the case of a transmitter, however, the desired matching impedance might not correspond to the dynamic output impedance of the transmitter as analyzed as a source impedance but rather the design value (typically 50 ohms) required for efficient and safe operation of the transmitting circuitry. The intended impedance is normally resistive but a transmitter (and some receivers) may have additional adjustments to cancel a certain amount of reactance in order to "tweak" the match. When a transmission line is used in between the antenna and the transmitter (or receiver) one generally would like an antenna system whose impedance is resistive and near the characteristic impedance of that transmission line in order to minimize the standing wave ratio (SWR) and the increase in transmission line losses it entails, in addition to supplying a good match at the transmitter or receiver itself.

What requires matching of the empedance to an antenna system?
Output: Maximum power transfer

Input: Article: The success of the British Commandos during World War II prompted U.S. President Franklin D. Roosevelt to authorize the creation of an intelligence service modeled after the British Secret Intelligence Service (MI6), and Special Operations Executive. This led to the creation of the Office of Strategic Services (OSS). On September 20, 1945, shortly after the end of World War II, Harry S. Truman signed an executive order dissolving the OSS, and by October 1945 its functions had been divided between the Departments of State and War. The division lasted only a few months. The first public mention of the "Central Intelligence Agency" appeared on a command-restructuring proposal presented by Jim Forrestal and Arthur Radford to the U.S. Senate Military Affairs Committee at the end of 1945. Despite opposition from the military establishment, the United States Department of State and the Federal Bureau of Investigation (FBI), Truman established the National Intelligence Authority in January 1946, which was the direct predecessor of the CIA. Its operational extension was known as the Central Intelligence Group (CIG)

Now answer this question: Who's secret intelligence service was the US's modeled after?

Output: British

Article: Incestuous matings by the purple-crowned fairy wren Malurus coronatus result in severe fitness costs due to inbreeding depression (greater than 30% reduction in hatchability of eggs). Females paired with related males may undertake extra pair matings (see Promiscuity#Other animals for 90% frequency in avian species) that can reduce the negative effects of inbreeding. However, there are ecological and demographic constraints on extra pair matings. Nevertheless, 43% of broods produced by incestuously paired females contained extra pair young.

Question: What can reduce the negative effects of inbreeding?
Ans: Females paired with related males may undertake extra pair matings

Here is a question about this article: A fervent follower of the absolutist cause, Elio had played an important role in the repression of the supporters of the Constitution of 1812. For this, he was arrested in 1820 and executed in 1822 by garroting. Conflict between absolutists and liberals continued, and in the period of conservative rule called the Ominous Decade (18231833), which followed the Trienio Liberal, there was ruthless repression by government forces and the Catholic Inquisition. The last victim of the Inquisition was Gaieta Ripoli, a teacher accused of being a deist and a Mason who was hanged in Valencia in 1824.
What is the answer to this question: Who helped repress the supporters of the Constitution and was later executed for it?
****
So... Elio

The word Ottoman is a historical anglicisation of the name of Osman I, the founder of the Empire and of the ruling House of Osman (also known as the Ottoman dynasty). Osman's name in turn was derived from the Persian form of the name Uthman of ultimately Arabic origin. In Ottoman Turkish, the empire was referred to as Devlet-i Aliyye-yi Osmaniyye ( ), (literally "The Supreme State of the Ottomans") or alternatively Osmanl Devleti ( ).[dn 5] In Modern Turkish, it is known as Osmanl Imparatorlugu ("Ottoman Empire") or Osmanl Devleti ("The Ottoman State").
In a literal sense what was the Ottoman empire referred to as?
****
The answer: The Supreme State of the Ottomans

The problem: Answer a question about this article:
In the wake of religious riots in Egypt, the emperor Decius decreed that all subjects of the Empire must actively seek to benefit the state through witnessed and certified sacrifice to "ancestral gods" or suffer a penalty: only Jews were exempt. Decius' edict appealed to whatever common mos maiores might reunite a politically and socially fractured Empire and its multitude of cults; no ancestral gods were specified by name. The fulfillment of sacrificial obligation by loyal subjects would define them and their gods as Roman. Roman oaths of loyalty were traditionally collective; the Decian oath has been interpreted as a design to root out individual subversives and suppress their cults, but apostasy was sought, rather than capital punishment. A year after its due deadline, the edict expired.
What religious group was exempt from sacrifices?
****
The answer:
Jews
