Q: Article: Disposing of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities,the waste disposal problem becomes increasingly difficult. During the eighteenth century,it was usual for several neighboring towns to get together to select a faraway spot as a dump site. People would transport household rubbish,rotted wood and old possessions to the site. Regularly some of the trash was burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody lived close by. Factories and some other industrial sites also had waste to be disposed of. Those located on rivers often just poured the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem. Several facts make these choices unacceptable to modern society. The first problem is space. Dumps , are most needed in heavily populated areas. Such areas rarely have empty land suitable. Farm areas are refusing to accept rubbish from elsewhere,cheap land in major city areas to dispose wastes is nonexistent . Awareness of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers,ground water,land and air is a price people can no longer pay to get rid of waste. The amount of waste,however, continues to grow. Recycling efforts have become commonplace,and many towns require their people to take part. Even the most efficient recycling programs,however,can hope to deal with only about 50 percent of a city's reusable waste,so more people should be involved in recycling programs.

Q: Article: Until a few months ago, he was a butler in one of the more expensive residential buildings in Manhattan. But now, Nepal-born Indra Tamang is the owner of two multi-million dollar apartments in the same building. The former owner - his former employer, Ruth Ford - died last year and left the apartments to Mr Tamang in her will. Mr Tamang is happy but quickly points out that his good fortune did not come easily. "I am happy and have been touched by the generosity of the Ford family," he says. "I never expected that I will be given the ownership of these apartments. But I have been working for the family for the last 36 years, devotedly, with honesty and dedication . So my hard work has been rewarded." Mr Tamang was 21 when he was brought from Nepal by Charles Ford, a writer and a photographer. Mr Ford died in 2002; his sister, actress Ruth Ford, then took charge and told Mr Tamang that he was like a brother to her after Charles's death. Mrs Ford died aged 98. During the last five years of her life, she lost her eyesight and also developed speech problems. Mr Tamang looked after her most of the time and took care of her medicines and food. He also worked with Charles Ford on various photography projects, which he now wants to keep as the photographer's legacy . He hopes to organize exhibitions of Mr Ford's photographs and edit a book of his works. Mr Tamang plans to sell the bigger, three-bedroom apartment to pay the taxes he owes to the government on his legacy. He says: "The rules of the building might be a problem, as they require a minimum monthly income to qualify to live as owner of apartments. I have my small house here but I am happy with it," Mr Tamang has learnt his lesson from the life of his employers and plans to use his money with great caution. "I think one should save money for old age. That's when you need it the most to get care," he says.

Q: Article: At times my mom has been uncomfortable seeing these qualities in me. For example,when I was 12,I went to Puerto Rico all by myself to stay with my grandmother for the summer. My mom was extremely nervous about it. She kept telling me how things were different in Puerto Rico,to always put on sunscreen,not to wander away from my grandmother,and other warnings. She helped me pack and did not leave the airport until she saw my plane take off. But despite her worries,she let me go on my own. As I moved into my teens,she continued to give me space to grow and learn,even when it might have been difficult for her. When I reached my senior year,I decided to move away for college. Once again I found that I differed from my peers:While many of them wanted to stay close to home,I couldn't wait to be out in the world on my own. While my mom may not have been happy at the thought of my going away,she was supportive and excited for me. One big thing I realized during my senior year,as my mom granted me more freedom,was that she actually believes in me and trusts me. That means a lot. Most of my life,and especially when I was little,the main person I tried to impress in my schoolwork or other things was my mother. I knew she expected nothing but the best from me. Sometimes it was hard to live up to her standards;getting a single B on my report card would make me feel bad because I knew she wanted me to have all A's. I know that her high standards have helped me stay focused on what's important,like education,and made me who I am. I am thankful for her support and involvement in my life .Most of all I respect her. She is the strongest woman I know and that's why I have turned out so strong and independent.
