Article: Finally, there is some good news for older dads. A new study shows that their children and even grandchildren may get a health benefit because of their older age. It's based on research into something called telomeres--tips on the ends of chromosomes Some previous studies have connected having longer telomeres with better health and longer lives. Telomeres haven't been proven to cause those benefits in the general population, but a number of researchers think they may hold secrets for things like longevity and cancer. As you age, telomeres shorten. However, previous studies have shown that the older a man is when he becomes a father, the longer the telomeres his children tend to have. The new research confirms that and finds it's extended to the grandchildren. That's a cheerier result for older dads than some other studies in recent years that indicate their kids are at higher risk for things like autism Carol Greider of Johns Hopkins University, who shared a Nobel Prize in 2009 for telomere research but didn't participate in the new study, said it's no surprise that the telomere effect would extend beyond children to grandchildren. She also said that since older fathers also tend to pass more potentially harmful genetic mutations , it's "not at all clear" whether advanced paternal age gives an overall health benefit to children. In a statement, the researchers who conducted the study said their study shouldn't be taken as a recommendation that men reproduce at older ages because there's a risk of genetic mutations. Some previous studies of the impact of older fatherhood have been less encouraging. In 2010, for example, at least two big studies confirmed a link to having children with autism. In 2008, a big Swedish study strengthened evidence linking bipolar disorder to older paternal ages. Question: What is the main idea of this passage? Yes or no, is the answer "Older dads might benefit the health of their children and grandchildren."?
No

Article: By taking a few simple techniques, parents who read to their children can greatly develop their children's language skills.It is surprising but true.How parents talk to their children makes a big difference in the children''s language development.If a parent encourages the child to actively respond to what the parent is reading.the child's language skills increase. A study was done with 30 three-year-old children and their parents.Half of the children took part in the experimental study;the other half acted as the control group.In the experimental group,the parents were given a two-hour training and they were taught to ask open-ended questions rather than yes-or-no questions.For example,the parent should ask,"What is the doggie doing?" rather than "Is the doggie running away?" The patents in the experimental group were also instructed in how to help children find answers,how to suggest different possibilities and how to praise correct answers. At the beginning of the study,the children did not differ in measures of language development,but at the end of one month,the children in the experimental group showed 5.5 months ahead of the control group on a test of expression and vocabulary.Nine months later,the children in the experimental group still showed an advance of 6 months over the children in the control group. Question: The difference between the control group and the experimental group was Yes or no, is the answer "the training that parents received"?

No

Ques: Article: According to the UN Intergovernmental Panel on Climate Change, global temperatures have risen by approximately 0.6degC in the past century, caused mainly by emissions of greenhouse gases produced by human activities,such as the burning of fossil fuels and deforestation.Temperatures are to increase between 1.6degC and 5.8degC in the next century, accompanied by sea level rise and an increase in the frequency of extreme weather events. The best available evidence suggests that climate changes since the 1970s may already be causing over 150,000 deaths annually, and that greenhouse gas emissions would increase disease burdens in the coming decades.The risks are concentrated in the poorest population, who have contributed least to the problem. The Kyoto Protocol is signed by 128 nations,and commits the participating industrialized countries to cutting emissions of greenhouse gases by over 5% below 1990 level by the period of 20082012. "Over 600 thousand people died in weatherrelated disasters in the 1990s.Temperature and rainfall influence the rates of diseases and infections including malaria,and malnutrition,which together cause over 3.5 million deaths a year.The Kyoto Protocol is the first step towards protecting the climate system,which exerts such a strong influence on our health",said Dr Kerstin Leitner,Assistant DirectorGeneral for Sustainable Development and Healthy Environments. While acting to reduce greenhouse gas emissions, it is also essential to protect vulnerable communities from the effects of climate changes.WHO works to promote measures such as protection from malaria and other climate sensitive diseases, and reliable access to clean water and sanitation, for people in the most vulnerable developing countries.Increasing disease control efforts will also help to protect current and future generations from the impacts of greenhouse gas emissions. Question: According to the passage, what is the reason for the rise of global temperatures? Yes or no, is the answer "The emissions of greenhouse gases."?
Ans: 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
