Ques:Read the following article and select the best answer. Article: Sleep deprivation is an important hidden factor in lowering the achievement of school pupils, according to researchers carrying out international education tests. It is a particular problem in richer countries with sleep experts linking it to the use of mobile phones and computers in bedroom late at night. Sleep deprivation is such a serious problem that lessons have to be dragged down to a lower level to suit sleep-deprived learners, the study found. The international comparison, carried out by Boston College, found the United States to have the highest number of sleep-deprived students, with 73% of 9- and 10-year-olds and 80% of 13- and 14-year-olds identified by their teachers as being negatively affected. In literacy tests there were 76% of 9- and 10-year-olds lacking sleep. This was much higher than the international average of 47% of primary pupils needing more sleep and 57% among the secondary age group. Other countries with the most sleep-deprived youngsters were New Zealand, Saudi Arabia, Australia, England, Ireland and France. High-performing Finland is also among the most lacking in sleep. Countries with the best records for getting enough sleep include Azerbaijan, Kazakhstan, Portugal, the Czech Republic, Japan and Malta. The analysis was part of the huge date-gathering process for global education rankings, the Trends in International Mathematics and Science Study(TIMSS)and Progress in International Reading Literacy Study(PIRLS) "I think we underestimate the impact of sleep. Our data show that across countries internationally, on average, children who have more sleep achieve higher in maths, science and reading. That is exactly what our data show," says Chad Minnich of the TIMSS and PIRLS International Study Center. "It's the same link for children who are lacking basic nutrition," says Mr Minnich, based at the Lynch School of Education, Boston College. "If you are unable to concentrate, to attend mentally, you are unable to achieve at your best level, because your mind and body are in need of...

Ques:Read the following article and select the best answer. Article: A new study links heavy air pollution from coal burning to shorter lives in northern China.Researchers guess that the half-billion people alive there in the 1990s will live an average of 5 years less than the southerners because they breathed dirtier air. China itself made the comparison possible for decades, a then government policy provided free coal for heating, but only in the colder north. Researchers found great differences in both air pollution and the length of life in the two areas. "This study provides a unique basis for the question about the life span in northern China because the heating policy dramatically changes pollution concentrations ," Michael Greenstone, a professor of environmental economics at Massachusetts Institute of Technology, said in an email, "Further,due to the low rates of migration in China in this period, we can know people's exposure over long periods". The policy gave free coal for fuel boilers to heat homes and offices to cities north of the Huai River which divides China into north and south. It was in effect for much of the 1950-1980 period, of central planning,and though such policy was stopped after 1980, the practice of heavy coal burning in the north goes on, which releases heavy pollutants into the air that can harm human health.Researchers found no other government policies that treated China's north differently from the south. The researchers collected data for 90 cities, from 1981 to 2000, on the annual daily average concentration of total particulates sent out from power stations,construction sites and vehicles. Among them, PM2.5 is of especially great health concern because it can go deep into the lungs. The researchers estimated the impact on the length of life using death data from 1991-2000.They found that in the north, the concentration of pollutants was 184 micrograms per cubic meter, 55 percent higher than in the south, and life length is 55 years lower on average. Question: According to Greenstone, what mainly caused the high pollution concentrations in North China? - power stations - construction sites - the government policy - gases from vehicles

Ans:the government policy

Ques:Read the following article and select the best answer. Article: A telescope , called Gaia, is being designed by astronomers in Europe, and it couldn't be more different from Pan-STARRS, which is another telescope being designed. While Pan-STARRS will be looking for asteroids and comets headed for Earth, Gaia will be looking at our entire galaxy . Gaia is designed to draw a map of the Milky Way, our home galaxy. Just as a map of your town gives you a picture of where things are located, Gaia's map of the galaxy will tell astronomers where the stars are. Over five years, Gaia will observe about a billion stars and other objects in our galaxy. Each object will be observed about 70 times. Gaia will be sent into space connected to a rocket. It contains two telescopes, each focused at a different angle . These two telescopes act like Gaia's "eyes". The reason why humans can see things in 3D is that we have two eyes focused on the same object, at slightly different angles. By using two telescopes like eyes, Gaia can produce the first 3D map of the positions of the stars it views. Gaia, which is to be sent into space in 2011, will be a powerful telescope. If you were to use it on Earth, for example, you could stand 600 miles away from your best friends and still get a clear picture of their hair. Gaia is one of more than a dozen telescopes being designed by scientists right now. The next generation of telescopes will reveal new parts of our universe that will seem surprising. The universe, with all its planets, stars and other strange objects, is a puzzle with pieces that we can see by using powerful telescopes. Question: How many different angles can Gaia focus at each time? - 2 . - 3. - 4 . - 5.

Ans:
2 .
