[Q]: Article: Former South African President Nelson Mandela who was treated for a recurring lung infection, dies on Dec. 5th, 2013, at the age of 95. People around the world are mourning the loss of the country's first black president. He was often called humble, charming, loyal person and a man who cared about others. "He seemed to have that special charismatic personality," said Herman Cohen, U.S. assistant secretary of state for Africa from 1989 to 1993. "He became the symbol in the fight against _ ." Mandela was born on July 18, 1918. As a young man he became active in the anti-apartheid movement and joined the African National Congress, or ANC, in the 1940s. The white-led government banned the ANC in 1960, but the group continued to operate secretly. Mandela became head of the group's new military wing, coordinating a sabotage campaign against South African military and government targets. In 1962, he was arrested and put on trial for his actions and sentenced to life in prison on Robben Island off the coast of Cape Town. He spent 18 years there, refusing a government offer to release him if he would renounce the ANC's armed struggle. But he was freed in 1990 after South African President Frederik de Klerk legalized all political parties and discharged most political prisoners. Shortly after his release, Mandela was elected president of the African National Congress. And in 1994, when the ANC won South Africa's first all-race elections, he was inaugurated as the county's first black president at age 75. "Never, never and never again shall it be that this beautiful land will again experience the oppression of one by another," he said. President Mandela said he would stay for only one five-year term. Cohen says Mandela earned international respect for South Africa's national reconciliation. "Mandela devoted himself mainly to rallying the Africans to this new era to work on economic development, having good education, also he was very much of a spokesman on the international scene." he said. In 1993, Mandela shared the Nobel Peace Prize with his once bitter enemy F.W. de Klerk for their contribution to the peace process in South Africa. After receiving the award, Mandela praised the South African people. "All have created a society which recognizes that all people are born equal," he said. In a country torn apart by years of racial conflict, Nelson Mandela is considered a remarkable leader -- a man who turned South Africa away from violence and hatred into a country of greater peace and understanding.

[Q]: Article: Our world is a noisy place, but quiet places remain. Eight years ago, audio engineer Gordon Hempton identified the quietest place in the continental United States. He calls the place "One Square Inch of Silence." He has used his symbolic spot in a northwestern rain forest to campaign against noise pollution. But the self-described "Sound Tracker" is now going deaf. For Gordon Hempton, it started with an experience known to many people. "I was lying in the bed in the springtime about a year ago. The sun was shining. The birds could be singing. They should be singing. But I was hearing none. I knew my life was going to be different." Hempton's eyes get watery as he describes his cruel situation. More than 20 years ago he trademarked his nickname as "The Sound Tracker." Sharp hearing defined his career as an Emmy award winning sound recordist. It also led to his activism against noise pollution. He has circled the globe three times in search of the perfect sounds of nature. Hempton says his hearing loss is quickly getting worse but he has to finish his project. "I am running a race to finish the Quiet Planet collection." That's the title of a planned 19-volume set of nature recordings. The sound tracks could be licensed for use in movies, video games, exhibits, plays and the like. Volunteer assistants now help Hempton review and edit sound files and identify imperfections. The exact cause of his hearing loss is not clear. Doctors say it may be the result of an infection, or a tumor or a combination of things. Hempton is self-employed. His health care plan does not pay for hearing loss treatment. So, for now, he's directing his attention to completing his "greatest hits" album. "After I get it finished, I have an economic cash flow to get my hearing back. That's the first thing on my to-do list." He's hopeful his hearing loss can be recovered.
