Example Input: 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.

Example Input: Article: The National Gallery of Art in Washington, D.C., is one of the world's greatest art museums. Millions of people have entered its doors to see paintings by the world's fine artists. But if these priceless masterpieces are to be preserved, the Gallery must protect them carefully. The Gallery's 135-man guard force has successfully prevented them from being stolen, but protecting the paintings from nature is a greater problem. In past times, the owners of paintings did not protect them from damaging changes in humidity and temperature. As a result, the life of these paintings were shortened. In the National Gallery, however, humidity and temperature are carefully controlled. The building is air-conditioned in summer and heated in winter. The air-conditioning and heating system are so important to the life of the painting that the Gallery has two of each system. If one should fail, the extra one can take over. Light is another enemy of paintings. Ultraviolet rays in light cause paintings to fade . Long ago, paintings often hung in dark churches and palaces. A coat of varnish was a protection from the weak light. But when museums took over the care of many paintings, they were often hung in brighter light than before. Soon they were in danger of fading. The damaging effects of light were increased when the museums removed the varnish coating, yellowed with age. To protect its paintings, the National Gallery put a special kind of glass in its skylights. This glass allows visible lights to enter the building but it keeps out harmful ultraviolet rays. The Gallery has also developed new and better varnishes which help to keep paintings from fading. Thanks to these new _ , many of the world's greatest paintings are being well protected for future generations to enjoy.
