Input: Read this: Southampton as a Port and city has had a long history of administrative independence of the surrounding County; as far back as the reign of King John the town and its port were removed from the writ of the King's Sheriff in Hampshire and the rights of custom and toll were granted by the King to the burgesses of Southampton over the port of Southampton and the Port of Portsmouth; this tax farm was granted for an annual fee of 200 in the charter dated at Orival on 29 June 1199. The definition of the port of Southampton was apparently broader than today and embraced all of the area between Lymington and Langstone. The corporation had resident representatives in Newport, Lymington and Portsmouth. By a charter of Henry VI, granted on 9 March 1446/7 (25+26 Hen. VI, m. 32), the mayor, bailiffs and burgesses of the towns and ports of Southampton and Portsmouth became a County incorporate and separate from Hampshire.
Question: What date was the charter regarding Southampton's tax farm signed at Orival?

Output: 29 June 1199

QUES: The town's first significant defences were likely erected due to commercial interests, following the temporary seizure of St. John's by the Dutch admiral Michiel de Ruyter in June 1665. The inhabitants were able to fend off a second Dutch attack in 1673, when this time it was defended by Christopher Martin, an English merchant captain. Martin landed six cannons from his vessel, the Elias Andrews, and constructed an earthen breastwork and battery near chain Rock commanding the Narrows leading into the harbour. With only twenty-three men, the valiant Martin beat off an attack by three Dutch warships. The English government planned to expand these fortifications (Fort William) in around 1689, but actual construction didn't begin until after the French admiral Pierre Le Moyne d'Iberville captured and destroyed the town in the Avalon Peninsula Campaign (1696). When 1500 English reinforcements arrived in late 1697 they found nothing but rubble where the town and fortifications had stood.

QUES: When comparing different documents, or "witnesses", of a single, original text, the observed differences are called variant readings, or simply variants or readings. It is not always apparent which single variant represents the author's original work. The process of textual criticism seeks to explain how each variant may have entered the text, either by accident (duplication or omission) or intention (harmonization or censorship), as scribes or supervisors transmitted the original author's text by copying it. The textual critic's task, therefore, is to sort through the variants, eliminating those most likely to be un-original, hence establishing a "critical text", or critical edition, that is intended to best approximate the original. At the same time, the critical text should document variant readings, so the relation of extant witnesses to the reconstructed original is apparent to a reader of the critical edition. In establishing the critical text, the textual critic considers both "external" evidence (the age, provenance, and affiliation of each witness) and "internal" or "physical" considerations (what the author and scribes, or printers, were likely to have done).
When do variations enter a witness text?

As an important railroad and road junction and production center, Hanover was a major target for strategic bombing during World War II, including the Oil Campaign. Targets included the AFA (Stocken), the Deurag-Nerag refinery (Misburg), the Continental plants (Vahrenwald and Limmer), the United light metal works (VLW) in Ricklingen and Laatzen (today Hanover fairground), the Hanover/Limmer rubber reclamation plant, the Hanomag factory (Linden) and the tank factory M.N.H. Maschinenfabrik Niedersachsen (Badenstedt). Forced labourers were sometimes used from the Hannover-Misburg subcamp of the Neuengamme concentration camp. Residential areas were also targeted, and more than 6,000 civilians were killed by the Allied bombing raids. More than 90% of the city center was destroyed in a total of 88 bombing raids. After the war, the Aegidienkirche was not rebuilt and its ruins were left as a war memorial.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many bombing raids destroyed 40% of the city?
Ah, so.. unanswerable

Question: The Royal College of Chemistry was established by private subscription in 1845 as there was a growing awareness that practical aspects of the experimental sciences were not well taught and that in the United Kingdom the teaching of chemistry in particular had fallen behind that in Germany. As a result of a movement earlier in the decade, many politicians donated funds to establish the college, including Benjamin Disraeli, William Gladstone and Robert Peel. It was also supported by Prince Albert, who persuaded August Wilhelm von Hofmann to be the first professor.

Question: This is a consequence of Lorentz reciprocity. For an antenna element not connected to anything (open circuited) one can write . But for an element which is short circuited, a current is generated across that short but no voltage is allowed, so the corresponding . This is the case, for instance, with the so-called parasitic elements of a Yagi-Uda antenna where the solid rod can be viewed as a dipole antenna shorted across its feedpoint. Parasitic elements are unpowered elements that absorb and reradiate RF energy according to the induced current calculated using such a system of equations.
Try to answer this question if possible: What element absorbs and reradiate RF-energy?
Answer:
Parasitic
