Question: In the absence of suitable plate culture techniques, some microbes require culture within live animals. Bacteria such as Mycobacterium leprae and Treponema pallidum can be grown in animals, although serological and microscopic techniques make the use of live animals unnecessary. Viruses are also usually identified using alternatives to growth in culture or animals. Some viruses may be grown in embryonated eggs. Another useful identification method is Xenodiagnosis, or the use of a vector to support the growth of an infectious agent. Chagas disease is the most significant example, because it is difficult to directly demonstrate the presence of the causative agent, Trypanosoma cruzi in a patient, which therefore makes it difficult to definitively make a diagnosis. In this case, xenodiagnosis involves the use of the vector of the Chagas agent T. cruzi, an uninfected triatomine bug, which takes a blood meal from a person suspected of having been infected. The bug is later inspected for growth of T. cruzi within its gut.
Try to answer this question if possible: What is it difficult to demonstrate the presence of in Chagas disease?
Answer: the causative agent
Question: The opposite of a Show Up is a "Rip". This is for sub-standard work, which is sometimes torn at the top of the page/sheet and must be submitted to the boy's housemaster for signature. Boys who accumulate rips are liable to be given a "White Ticket", which must be signed by all his teachers and may be accompanied by other punishments, usually involving doing domestic chores or writing lines. In recent times,[when?] a milder form of the rip, 'sign for information', colloquially known as an "info", has been introduced, which must also be signed by the boy's housemaster and tutor.
Try to answer this question if possible: Who must sign a Rip?
Answer: the boy's housemaster
Question: Chopin's successes as a composer and performer opened the door to western Europe for him, and on 2 November 1830, he set out, in the words of Zdzisaw Jachimecki, "into the wide world, with no very clearly defined aim, forever." With Woyciechowski, he headed for Austria, intending to go on to Italy. Later that month, in Warsaw, the November 1830 Uprising broke out, and Woyciechowski returned to Poland to enlist. Chopin, now alone in Vienna, was nostalgic for his homeland, and wrote to a friend, "I curse the moment of my departure." When in September 1831 he learned, while travelling from Vienna to Paris, that the uprising had been crushed, he expressed his anguish in the pages of his private journal: "Oh God! ... You are there, and yet you do not take vengeance!" Jachimecki ascribes to these events the composer's maturing "into an inspired national bard who intuited the past, present and future of his native Poland."
Try to answer this question if possible: In what year did his companion Woyciechowski depart to Poland to enlist for the uprising in Warsaw?
Answer: 1830
Question: In November 1795, there was a debate in Parliament on the high price of corn and Burke wrote a memorandum to Pitt on the subject. In December Samuel Whitbread MP introduced a bill giving magistrates the power to fix minimum wages and Fox said he would vote for it. This debate probably led Burke to editing his memorandum, as there appeared a notice that Burke would soon publish a letter on the subject to the Secretary of the Board of Agriculture, Arthur Young; but he failed to complete it. These fragments were inserted into the memorandum after his death and published posthumously in 1800 as, Thoughts and Details on Scarcity. In it, Burke expounded "some of the doctrines of political economists bearing upon agriculture as a trade". Burke criticised policies such as maximum prices and state regulation of wages, and set out what the limits of government should be:
