[EX Q]: Article: His first fight was for the equal rights of black people in South Africa. Then, as the first black president he fought to unite the country and organize the government. Now Nelson Mandela has set his sights on a new enemy, AIDS. On March 19 the 82-year-old, former president, hosted his second AIDS-awareness concert. He warned that 25 million people in Africa were already infected with the fatal disease. Mandela was born in a small village in South Africa in 1918. He was adopted by the chief of his tribe and could have been a chief himself and lived a happy country life. But he refused to be a chief when his people lived under racial discrimination ( ). He decided to fight for equal rights for all the people in South Africa. Before 1990, under the country's Racial Segregation Law , colored and white people lived separately. Black people were treated unfairly even when taking a bus. Blacks had to stand at the back of the bus to make room for white people even when there were only a few of them on board. For his opposition to the system Mandela was arrested and spent 27 years in prison. He was freed in 1990 and become the president of the country after the first elections were held in which everyone could vote. Mandela was not only a political fighter who attacked with speeches. He was also a trained boxer and fought in the ring when he was young. " Although I did not enjoy the violence of boxing, I was interested in how one moved one's body to protect oneself, how one used a strategy both to attack and retreat ," he wrote in his autobiography. As a skilful fighter, he chose music as his weapon against AIDS. He hopes to win another victory against AIDS.

[EX Q]: Article: Mary Jean Price Walls graduated second in her class in 1950.She had high hopes when she applied to a local college,Southwest Missouri State College.But after sending off her application,she spent months waiting for a reply.It never came. Worse than simply being denied admission ,the school didn't reply to her at all.It wasn't a matter of her school records,but of her skin color:Wallsis African American,and in those days,that fact alone closed a lot of doors. "I was sad and I was hurt,"Walls toldABCNews."I did not expect the skin color would affect my application.I thought I could go to university like other students." Four years later,the government declared that all schools should not discriminate against African Americans-- but it was too late for Walls.She'd moved on with her life, becoming a wife and a mother,and working as an elevator operator.She retired last year,at the age of 77. She stayed quiet about the unfairness she'd faced in Missouri State.Her son,Terry,went through school records and found that she'd been the first black student to ever apply to the college.Today,four percent of the Southwest Missouri State College body is African American--including Terry. Although it's too late for Missouri State to change the past,the school is awarding Walls with an honorary degree from the school.While she knows it's too late for herto change the course of her own life with the degree,it's a chance for her to show her family that Missouri State has changed in the last 60 years,and there's not a single door closed to them anymore.

[EX Q]: Article: In the United States alone,over 100 million cell-phones are thrown away each year.Cell-phones are part of a growing mountain of electronic waste like computers and personal digital assistants.The electronic waste stream is increasing three times taster than traditional garbage as a whole. Electronic devices contain valuable metals such as gold and silver.A Swiss study reported that while the weight of electronic goods represented by precious metals was relatively small in comparison to total waste,the concentration of gold and other precious metals was higher in So-called e-waste than in naturally occurring minerals. Electronic wastes also contain many poisonous metals.Even when the machines are recycled and the harmful metals removed,the recycling process often is carried out in poor countries,in practically uncontrolled ways which allow many poisonous substances to escape into the environment. Creating products out of raw materials creates much more waste material,up to 100 times more,than the material contained in the finished products.Consider again the cell-phone,and imagine the mines that produced those metals,the factories needed to make the box and packaging it came in.Many wastes produced in the producing process are harmful as well. The U.S Environmental Protection Agency notes that most waste is dangerous in that"the production, distribution,and use of products-as well as management of the resulting waste-all result in greenhouse gas release." Individuals can reduce their contribution by creating less waste at the start-for instance,buying reusable products and recycling. In many countries the concept of extended producer responsibility is being considered or has been put in place as an incentive for reducing waste.If producers are required to take back packaging they use to sell their products,would they reduce the packaging in the first place? Governments' incentive to require producers to take responsibility for the packaging they produce is usually based on money.Why,they ask,should cities or towns be responsible for paying to deal with the bubble wrap that encased your television? From the governments' point of view,a primary goal of laws requiring extended producer responsibility is to transfer both the costs and the physical responsibility of waste management from the government and tax-payers back to the producers.
