Input: Read this: Muslims believe the Quran was verbally revealed by God to Muhammad through the angel Gabriel (Jibril), gradually over a period of approximately 23 years, beginning on 22 December 609 CE, when Muhammad was 40, and concluding in 632, the year of his death. Muslims regard the Quran as the most important miracle of Muhammad, a proof of his prophethood, and the culmination of a series of divine messages that started with the messages revealed to Adam and ended with Muhammad. The word "Quran" occurs some 70 times in the text of the Quran, although different names and words are also said to be references to the Quran.
Question: What is the Jewish variant of Gabriel?

Output: unanswerable

QUES: The Kpelle comprise more than 20% of the population and are the largest ethnic group in Liberia, residing mostly in Bong County and adjacent areas in central Liberia. Americo-Liberians, who are descendants of African American and West Indian, mostly Barbadian settlers, make up 2.5%. Congo people, descendants of repatriated Congo and Afro-Caribbean slaves who arrived in 1825, make up an estimated 2.5%. These latter two groups established political control in the 19th century which they kept well into the 20th century.

What is the largest ethnic group in Congo?
What is the answer?

QUES: Taira Kiyomori emerged as the real power in Japan following the Minamoto's destruction, and he would remain in command for the next 20 years. He gave his daughter Tokuko in marriage to the young emperor Takakura, who died at only 19, leaving their infant son Antoku to succeed to the throne. Kiyomori filled no less than 50 government posts with his relatives, rebuilt the Inland Sea, and encouraged trade with Sung China. He also took aggressive actions to safeguard his power when necessary, including the removal and exile of 45 court officials and the razing of two troublesome temples, Todai-ji and Kofuku-ji.
What was the name of Takakura's successor?

ANS: Antoku

In the early 11th century, the Muslim physicist Ibn al-Haytham (Alhacen or Alhazen) discussed space perception and its epistemological implications in his Book of Optics (1021), he also rejected Aristotle's definition of topos (Physics IV) by way of geometric demonstrations and defined place as a mathematical spatial extension. His experimental proof of the intromission model of vision led to changes in the understanding of the visual perception of space, contrary to the previous emission theory of vision supported by Euclid and Ptolemy. In "tying the visual perception of space to prior bodily experience, Alhacen unequivocally rejected the intuitiveness of spatial perception and, therefore, the autonomy of vision. Without tangible notions of distance and size for correlation, sight can tell us next to nothing about such things."
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Alhazen's experimental proof of the intromission model of vision led to the change of understanding of what?
Ah, so.. Without tangible notions of distance and size for correlation, sight can tell us next to nothing about such things

Question: Under the early courts, when military conscription had been centrally controlled, military affairs had been taken out of the hands of the provincial aristocracy. But as the system broke down after 792, local power holders again became the primary source of military strength. The re-establishment of an efficient military system was made gradually through a process of trial-and-error. At that time the imperial court did not possess an army but rather relied on an organization of professional warriors composed mainly of oryoshi, which were appointed to an individual province and tsuibushi, which were appointed over imperial circuits or for specific tasks. This gave rise to the Japanese military class. Nonetheless final authority rested with the imperial court.
Try to answer this question if possible: What was in the hands of the provincial aristocracy in he early courts?
Answer: unanswerable

Problem: So an additional problem beyond canceling the unwanted reactance is of matching the remaining resistive impedance to the characteristic impedance of the transmission line. In principle this can always be done with a transformer, however the turns ratio of a transformer is not adjustable. A general matching network with at least two adjustments can be made to correct both components of impedance. Matching networks using discrete inductors and capacitors will have losses associated with those components, and will have power restrictions when used for transmitting. Avoiding these difficulties, commercial antennas are generally designed with fixed matching elements or feeding strategies to get an approximate match to standard coax, such as 50 or 75 Ohms. Antennas based on the dipole (rather than vertical antennas) should include a balun in between the transmission line and antenna element, which may be integrated into any such matching network.
What is included between the transmission line and the antenna element?
---
Answer:
balun
