Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: prefix = st1 /LONDON-The tiny, distant and frozen planet Pluto, for 30 years believed to have just one moon, has suddenly been found to have two more satellites. Only discovered in 1930 because of its vast distance from Earth, Pluto has remained a largely mysterious object ever since. Some three billion miles from the Sun, Pluto, a dwarf planet, remains to be visited by a spacecraft. Its first known satellite is called Charon . With a diameter of 1,200 km , it is half that of Pluto-unusually large for a moon in relation to its _ . But now , using images from the Hubble Space Telescope , scientists from Johns Hopkins University , Southwest Research Institute and the Massachusetts instituteofTechnologysay they have found two more tiny orbiting satellites , P1 and P2. Both are traveling outside the orbit of Charon and are tiny by comparison , the scientists wrote in the journal Nature. P1, the more distant of the two from Pluto , has a diameter of between 60 and 165 km while P2 is 20 percent smaller . "Although definitive orbits cannot be obtained , both new satellites appear to be moving in circular orbits in the same orbital plane as Charon with orbital periods of about 38 days for P1 and 25 days for P2," they wrote . The discovery of the two new members of P1uto's family makes it the only object in the Kuiper belt--a vast region of rock and ice beyond Neptune which contains debris from the formation of the solar system--known to have multiple satellites , the scientists said . Options: A Charon was not discovered until the late 1960s . B Charon is the largest satellite in the solar system C all the inner planets are better observed than Pluto D Pluto may have some more moons to be discovered Answer: C all the inner planets are better observed than Pluto Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and 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.

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: More than a third of the babies born this year could receive a 100th birthday message from whoever happens to be on the throne in the second decade of the 22nd century, according to figures published by the Office for National Statistics (ONS). It forecasts that 35% of the 826,000 people born in 2012 will live to become _ . But a long life is not unalloyed good news. David Sinclair, head of policy and research at the International Longevity Centre UK, warned that for many the future may mean social isolation as they live longer than friends and members of their families. "It is of course good news that so many more people are living longer," he said, "but there is a big 'but1. We will be older, but in worse health, and at high risk of living alone. The other problem is that we are very poor at forward planning. We deal with the problems that are under our noses, but even problems two or three years away seem quite distant enough to put off.When you're talking about forecasts for a time half a century away and more, I see no evidence that we are putting in place the measures to deal with it." This year there will be 14,500 centenarians in the UK, a number which is expected to increase to 110,000 in 2035. Women have higher life expectancies than men at every age: the likelihood of a girl born this year reaching her century is estimated to be 39%; for boys the figure is 32%. The estimated number of female centenarians has risen from 500 in 1961 to more than 10,000 in 2010,a figure which is projected to reach 71,000 by 2035 and 276,000 by 2060. Men are also living far longer, although their numbers are far fewer. There were an estimated 92 male centenarians in 1961 and just below 2,000 in 2010. Options: A A long life is not always good news. B A long life also means social and physical isolation C In the future, more people will live to 100 in the UK. D It is good to live to 100. Answer: C In the future, more people will live to 100 in the UK. Question:
