Question: Article: "Is it possible for Brownie not to be glad to be back after a happy stay at my uncle's?"Miss Gauss asked Dad."It'll be all right. Give her a bit more to eat," he said in a low voice, without tearing his eyes from Brownie while his wife was busy packing Brownie's belongings, saying,"Brownie is not so cute as her younger brother, Spotty. Take care of the little thing when walking him." It happened on the night of July 10th, 2013 before the Gausses took a trip to Hawaii. They entrusted their pet to me because they thought I was the first person they'd confide in. And another intention of theirs was that I had already trained Spotty into a wellknown pet in my community, which can act many tricks, such as "Sit down!" "Stand up!" "Give me your right hand!" "Turn around!" She can even sing, and, of course, that's just a strange sharp noise. Having seen them off, I took beautiful Brownie home in my arms, for fear that he would slip away. _ so I tried many ways to be his friend, which made Spotty rather unhappy. They often fought a battle, seemingly to break my roof loose. Soon, Brownie turned out to be an agreeable family member. He was an endearing pet, often begging for comforts in my arms. I seized the chance to train him and he achieved a lot, which I texted Mr.Gauss. They were so overjoyed and decided to fly home ahead of time to see Brownie's qualitative change. But,all this was thoroughly destroyed because of Brownie's death in a traffic accident. What a poor little creature!He was really dogged by bad luck, and he was saved from death shortly after his birth. For whatever reason,therefore, I was overwhelmed by feelings of guilt, which seemed to run most deeply in me. The best way to cheer ourselves up is to try first to cheer somebody else up. That will be an everlasting pain in my heart, a wound that does not heal.
Answer: his owners would go on a trip

Question: Article: London--A morning's train ride away, across the Channel, English kids talk about Liverpool's soccer team in a Paris puB.Some Parisians have even started to go to work in London.In the 19thcentury, Charles Dickens compared the two great rival cities, London and Paris, in " A Tale of Two Cities".These days, it might be A Tale of One City. Parisians are these days likely to smile in sympathy at a visitor's broken French and respond in polite English.As jobs grew lack at home over recent years, perhaps 250,000 Frenchmen moved across the Channel.With an undersea tunnel, they could travel between cities in three hours.The European Union freed them from immigration and customs. Paris, rich in beauty, is more attractive.But London feels more full of life, and more fun until the pubs shut down. "For me, the difference is that London is real, alive," said Trevor Wheeler, a banker. Chantal Jaouen, a professional designer, agrees."I am French, but I'll stay in London," she saiD. There is, of course, the other view.Julie Lenoux is a student who moved to London two years ago."I think people laugh more in Paris," she saiD. In fact, London and Paris, with their obvious new similarities, are beyond the old descriptions.As the European Union gradually loosened controls, Londoners _ into Paris to shop, eat and buy property . "Both cities have changed beyond recognition." Said Larry Collins, a writer and sometimes a Londoner.Like most people who know both well, he finds the two now fit together comfortably. "I first fell in love with Paris in the 1950s and it is still a wonderful place," Collins saiD."But if I had to choose, it would be London.Things are so much more ordered, and life is better." But certainly not cheaper.In fancy parts of London, rents can be twice those on Avenue Foch in Paris.Deciding between London and Paris requires a lifestyle choice. Like Daphne Benoit, a French journalism student with perfect English, many young people are happy to be close enough so they don't have to choose. "I love Paris, my little neighborhood, the way I can walk around a centre, but life is so structured," she saiD."In London, you can be who you want.No one cares."

Question: Article: William Herschel was born on November 15th, 1738 in Hanover in a family of musicians. In 1757,he fled to England and began earning a living as an organist and later composer and conductor. In 1772, he convinced his sister Caroline to join him as a singer. In their spare time the brother-sister team became occupied in astronomy. William died at his home in Slough, near Windsor on August 25th,1822,and Caroline on September 1st,1848. Herschel's first major discoveries were to show that Mars and Jupiter exhibit axial rotation . Herschel struck fame in 1781,when on March 13th he discovered the planet Uranus while engaged in work aimed at determining stellar parallax .This being the first new planet discovered since ancient times, Herschel, until then a mere amateur astronomer relatively unknown even in England, became world-famous. Adopting a historically proven strategy, Herschel named the new planet Georgium Sidum,in honor of the then ruling English king GeorgeIII. The trick worked once again, as King GeorgeIII gave William and Caroline the titles of"The King's Astronomer"and"Assistant to the King's Astronomer", an honor which came with a life's pension for both. In 1782 they moved to Bath, and shortly thereafter to Slough, and from this point on William and Caroline could devote themselves entirely to astronomy. The Herschels went on to discover two moons of Uranus in 1787. While Caroline became increasingly occupied with the search for comets at which she was quite successful, William became for a time interested in the Sun. Inspired by Wilson's 1774 work, he put forth the theory of sunspots ,an opinion that continued to exist well into the nineteenth century. In 1800,he became interested in the solar spectrum ,and uncovered the first evidence for solar energy output outside of the visible spectrum, in what is now known as the infrared .In 1801, he published two papers that effectively started the field of solar influences on Earth's weather.
