- In the past, the WHO did not take into account the overlap between exposure to both forms.
- Air pollution by sources ranging from cooking fires to auto fumes caused an estimated seven million deaths worldwide in 2012.
- According to the WHO, some 2.9 billion people use fires as their principle method of cooking and heating.
- The WHO will release a ranking of the world's 1,600 most polluted cities by the end of this year. Now, answer this question: Read the following article and answer the question. Article: Air pollution by sources ranging from cooking fires to auto fumes contributed to an estimated seven million deaths worldwide in 2012, the UN health agency has said. "Air pollution, and we're talking about both indoors and outdoors, is now the biggest environmental health problem, and _ is affecting everyone, both developed and developing countries," said Maria Neira, the World Health Organisation's public and environmental health chief. Globally, pollution was linked to one death in eight in 2012, new WHO research found. The biggest pollution-related killers were heart disease, stroke, pulmonary disease and lung cancer. The hardest-hit regions of the globe were what the WHO labels Southeast Asia, which includes India and Indonesia, and the Western Pacific, ranging from China and South Korea to Japan and the Philippines. Together, they accounted for 5.9 million deaths. The global death toll included 4.3 million deaths due to indoor air pollution, chiefly caused by cooking over coal, wood and biomass stoves. The toll from outdoor pollution was 3.7 million, with sources ranging from coal heating fires to diesel engines. Many people are exposed to both indoor and outdoor pollution, the WHO said, and due to that overlap the separate death toll attributed to the two sources cannot simply be added together, hence the figure of seven million deaths. The new figure is "shocking and worrying", Ms Neira told reporters. When it last released an estimate for deaths related to air pollution, in 2008, the agency had put the figure related to outdoor pollution at 1.3 million, while the number blamed on indoor pollution was 1.9 million. But a change in research methods makes comparison difficult between the 2008 estimate and the 2012 figures, Neira said. In the past, for example, the WHO did not take into account the overlap between exposure to both forms, and only assessed urban pollution. Satellite imagery has made it easier to assess rural pollution, and new knowledge about the health impact of exposure has enabled a... Question: The main idea of this article is that _ . Answer:

Dollar bills are made so that they are interesting to look at but very hard to copy. In total, there are sixty-five separate steps required to make a dollar bill. The money making process begins when. a yearly order is sent by the Federal Reserve Board. That order will then be divided in half. Half will be done here in Washington, D. C.and the other half will be done in Fort Worth, Texas. Next, the Bureau orders special paper which is actually cloth since it is 75% cotton and 25% linen. This paper is made so that it can last a long time. And, it is made with details that make it hard to copy. For example, bills contain security threads. These narrow pieces of plastic are inside the paper and run along the width of the bill. This special paper is also made with very small blue and red fibers. Once the money is printed, guillotine cutters separate the sheets into two notes, then into individual notes. The notes are organized in "bricks," each of which contains forty one-hundred-note packages. The bricks then go to one of twelve Federal Reserve Districts, which then give the money to local banks. Ninety-five percent of the bills printed each year are used to replace money that is in circulation, or that has already been removed from circulation. You may know that America's first president, George Washington, is pictured on the one- dollar bill. But do you know whose face is on the two, five, ten, twenty, fifty and one hundred-dollar bills? They are, in order. President Thomas Jefferson, President Abraham Lincoln, Treasury Secretary Alexander Hamilton, President Andrew Jackson, President Ulysses Grant and statesman Benjamin Franklin. The average life span of a one-dollar bill is twenty-one months. But a ten-dollar bill lasts only about eighteen months. The one hundred-dollar bill lasts the longest, eighty-nine months. One popular question is about the two-dollar bill. This bill is not printed very often. This is because many Americans believe... Question: How many presidents are printed on the American money?
