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 _ . Yes or no, is the answer "Air pollution by sources ranging from cooking fires to auto fumes caused an estimated seven million deaths worldwide in 2012."?
Answer: Yes

Question: Article: Adding math talk to story time at home is a winning factor for children's math achievement, according to a new research from the University of Chicago. The study from psychologists Sian Beilock and Susan Levine shows a marked increase in math achievement among children whose families used Bedtime Math, an iPad app that delivers engaging math story problems for parents and children to solve together. Even children who used the app with their parents as little as once a week saw gains in math achievement by the end of the school year. The app's effect was especially strong for children whose parents tend to be anxious or uncomfortable with math. Previous research from this group has demonstrated the importance of adults' attitudes about math for children's math success. For example, a recent study found that math-anxious parents who help their children with math homework actually weaken their children's math achievement. The new findings demonstrate that structured, positive interactions around math at home can cut the link between parents' uneasiness about math and children's low math achievement. "Many Americans experience high levels of anxiety when they have to solve a math problem, with a majority of adults feeling at least some worries about math," said Beilock, professor in Psychology and author of Choke, a book about stress and performance. "These math-anxious parents are probably less likely to talk about math at home, which affects how competent their children are in math. Bedtime Math encourages a dialogue between parents and kids about math, and offers a way to engage in high-quality math interactions in a low-effort, high-impact way." Study participants included 587 first-grade students and their parents. Families were given an iPad installed with a version of the Bedtime Math app, with which parents and their children read stories and answer questions involving math, including topics like counting, shapes and problem-solving. A control group received a reading app that had similar stories without... Question: Bedtime Math is an iPad app that _ . Yes or no, is the answer "encourages children together with their parents to solve math story problems"?
Answer: No

Question: Article: Except for the sun, the moon looks like the biggest object in the sky. Actually it is one of the smallest, and only looks big because it is so near to us. Its diameter is only 2,160 miles (3,389 km), or a little more than a quarter of the diameter of the earth. Once a month, or more exactly, once every 29.5 days, at the time we call "full moon," its whole _ looks bright. At other times only part of it appears bright, and we always find that this is the part which faces towards the sun, while the part racing away from the sun appears dark. People could make their pictures better if they kept this in mind -- only those parts of the moon which are lighted up by the sun are bright. This shows that the moon gives no light of its own. It only throws back the light of the sun, like a huge mirror hung in the sky. Yet the dark part of the moon's surface is not ly black; generally it is just light enough for us to be able to see its outline, so that we speak of seeing "the old moon in the new moon's arms." The light by which we see the old moon does not come from the sun, but from the earth. We know well how the surface of the sea or of snow, or even of a wet road, may throw back uncomfortably much of the sun's light onto our faces. In the same way the surface of the whole earth throws back enough of the sun's light on to the face of the moon for us to be able to see the parts of it which would otherwise be dark. Question: Why is the dark part of the moon not completely black? Yes or no, is the answer "Because the earth throws back sunlight onto the moon."?
Answer:
No
