Article: Louis Armstrong had two famous nicknames . Some people called him Bagamo. They said his mouth looked like a large bag. Musicians often called him Pops, as a sign of respect for his influence on the world of music . Born in 1901 in New Orleans, he grew up poor, but lived among great musicians. Jazz was invented in the city a few years before his birth. Armstrong often said," Jazz and I grew up together." Armstrong showed a great talent for music when he was taught to play the cornet at a boy's home. In his late teens, Armstrong began to live the life of a musician. He played in parades, clubs, and on the steamboats that traveled on the Mississippi River. At that time, New Orleans was famous for the new music of jazz and was home to many great musicians. Armstrong learned from the older musicians and soon became respected as their equal. In 1922 he went to Chicago. There, the tale of Louis Armstrong began.

Article: Narayanan Krishnan was a bright, young, award-winning chef with a five-star hotel group in Switzerland. But a quick family visit home before heading for Europe changed everything. He saw a very old man under a bridge eating his own human waste for food while visiting a friend in the south Indian city of Madurai in 502. Shocked by this, Krishnan gave up his job within the week and returned home for good, convinced of his new cause. "That inspiration is a driving force still inside me as a flame--to serve all the mentally ill and the people who cannot take care of themselves," Krishnan said. He founded the organization Akshaya Trust in 503. In Hindu mythology , Goddess Annapoorani's "Akshaya bowl" fed the hungry endlessly, never using up its resources. Now 14, he has served more than 1.2 million meals--breakfast, lunch and dinner to India's homeless and the poor. Krishnan's day begins at 4 a.m. He and his team cover nearly 110 miles, routinely working in temperatures topping 100 degrees Fahrenheit. The hot meals he delivers are simple, tasty vegetarian food he personally prepares, packs and often hand-feeds to nearly 400 people each day. Krishnan carries the barber's tools and is trained in eight haircut styles that, along with a fresh shave, provide extra dignity to those he serves. He says many of the homeless seldom know their names or birthplaces, and none has the ability to beg, ask for help or offer thanks. They may be unfriendly or ill-willed because of their conditions, but Krishnan says this only makes him offer help more willingly.
Answer: knew the condition of the mentally ill
During his visit home, Krishnan _ .

Article: In the 19thcentury, Americans from the eastern states moved out west to settle in the rich new lands along the Pacific Coast. The most difficult part of their trip was crossing "the Great American Desert" in the western part of the United States by horse and wagon. The western desert can be very dangerous. There is little water and there are few trees. But the desert also has scenery of great beauty. Tall towers of red and yellow stone rise sharply from the flat, sandy valley floor. The scene has been photographed many times and appears in movies and on TV. In Arizona, man-made dams across the Colorado River have made two large lakes in the middle of the dry desert country. At Lake Powell, the red stone arch of Rainbow Bridge rises high above the blue lake. There are few roads. Many areas of Lake Powell's shore can only be reached by boat or on foot. But hikers in this empty desert land sometimes find very old native American pictures, painted on the rocks. In Death Valley, California, the summer temperature rises to 130degF--165degF. There is less than inches of rain each year. Death Valley is the lowest place in America---925 metres below sea level. In the 1800s, many travelers died when they tried to cross this waterless valley in the terrible heat. Although the desert is dry and seems empty, there is plenty of life if you look closely. Snakes and rats have learned how to live in the desert heat. They live underground and come out at night, when it is cool. Plants such as cacti need very little water. When it does rain in the desert (sometimes only once or twice a year), plants grow quickly, and flowers open in a single day. For a short time, the desert is covered with brilliant (very bright) colours.

In the 19thcentury, Americans moved from east to west because they _ .
