Input: Read this: A samurai could take concubines but their backgrounds were checked by higher-ranked samurai. In many cases, taking a concubine was akin to a marriage. Kidnapping a concubine, although common in fiction, would have been shameful, if not criminal. If the concubine was a commoner, a messenger was sent with betrothal money or a note for exemption of tax to ask for her parents' acceptance. Even though the woman would not be a legal wife, a situation normally considered a demotion, many wealthy merchants believed that being the concubine of a samurai was superior to being the legal wife of a commoner. When a merchant's daughter married a samurai, her family's money erased the samurai's debts, and the samurai's social status improved the standing of the merchant family. If a samurai's commoner concubine gave birth to a son, the son could inherit his father's social status.
Question: What happened if a commoner concubine had a son?

Output: the son could inherit his father's social status


QUES: The majority of Freemasonry considers the Liberal (Continental) strand to be Irregular, and thus withhold recognition. For the Continental lodges, however, having a different approach to Freemasonry was not a reason for severing masonic ties. In 1961, an umbrella organisation, Centre de Liaison et d'Information des Puissances maçonniques Signataires de l'Appel de Strasbourg (CLIPSAS) was set up, which today provides a forum for most of these Grand Lodges and Grand Orients worldwide. Included in the list of over 70 Grand Lodges and Grand Orients are representatives of all three of the above categories, including mixed and women's organisations. The United Grand Lodge of England does not communicate with any of these jurisdictions, and expects its allies to follow suit. This creates the distinction between Anglo-American and Continental Freemasonry.

What is the Continental Strand consideres to be by most of Freemasonry?
What is the answer?
ANS: Irregular


QUES: Baroque music is characterized by the use of complex tonal counterpoint and the use of a basso continuo, a continuous bass line. Music became more complex in comparison with the songs of earlier periods. The beginnings of the sonata form took shape in the canzona, as did a more formalized notion of theme and variations. The tonalities of major and minor as means for managing dissonance and chromaticism in music took full shape.
What does basso continuo mean? 

ANS: a continuous bass line


In The Sensory Order: An Inquiry into the Foundations of Theoretical Psychology (1952), Hayek independently developed a "Hebbian learning" model of learning and memory – an idea which he first conceived in 1920, prior to his study of economics. Hayek's expansion of the "Hebbian synapse" construction into a global brain theory has received continued attention in neuroscience, cognitive science, computer science, behavioural science, and evolutionary psychology, by scientists such as Gerald Edelman, and Joaquin Fuster.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did Hayek present in his 1952 book that affected multiple areas of science?
Ah, so.. "Hebbian synapse"


Question: Athens retained its position as the most prestigious seat of higher education, especially in the domains of philosophy and rhetoric, with considerable libraries and philosophical schools. Alexandria had the monumental Museum (i.e. research center) and Library of Alexandria which was estimated to have had 700,000 volumes. The city of Pergamon also had a large library and became a major center of book production. The island of Rhodes had a library and also boasted a famous finishing school for politics and diplomacy. Libraries were also present in Antioch, Pella, and Kos. Cicero was educated in Athens and Mark Antony in Rhodes. Antioch was founded as a metropolis and center of Greek learning which retained its status into the era of Christianity. Seleucia replaced Babylon as the metropolis of the lower Tigris.
Try to answer this question if possible: What replaced Babylon as the metropolis of the lower Tigris?
Answer: Seleucia


Context and question: 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?
Answer:
Maximum power transfer
