Article: 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."

Question: On what date did Frederic begin his journey into Western Europe?
Ans: 2 November 1830

Article: Insects were the earliest organisms to produce and sense sounds. Insects make sounds mostly by mechanical action of appendages. In grasshoppers and crickets, this is achieved by stridulation. Cicadas make the loudest sounds among the insects by producing and amplifying sounds with special modifications to their body and musculature. The African cicada Brevisana brevis has been measured at 106.7 decibels at a distance of 50 cm (20 in). Some insects, such as the Helicoverpa zeamoths, hawk moths and Hedylid butterflies, can hear ultrasound and take evasive action when they sense that they have been detected by bats. Some moths produce ultrasonic clicks that were once thought to have a role in jamming bat echolocation. The ultrasonic clicks were subsequently found to be produced mostly by unpalatable moths to warn bats, just as warning colorations are used against predators that hunt by sight. Some otherwise palatable moths have evolved to mimic these calls. More recently, the claim that some moths can jam bat sonar has been revisited. Ultrasonic recording and high-speed infrared videography of bat-moth interactions suggest the palatable tiger moth really does defend against attacking big brown bats using ultrasonic clicks that jam bat sonar.

Question: Moths create what kind of click sounds?
Ans: ultrasonic

Article: Traditionally a carnival feast was the last opportunity to eat well before the time of food shortage at the end of the winter during which one was limited to the minimum necessary. On what nowadays is called vastenavond (the days before fasting) all the remaining winter stores of lard, butter and meat which were left would be eaten, for it would soon start to rot and decay. The selected livestock had in fact already been slaughtered in November and the meat would be no longer preservable. All the food that had survived the winter had to be eaten to assure that everyone was fed enough to survive until the coming spring would provide new food sources.

Question: What was one limited to during the winter?
Ans: the minimum necessary
