Article: The Curious Incident of the Dog in the Night-Time is a novel about a 15-year-old autistic boy named Christopher Boone. After discovering the dead body of Wellington, his neighbor's dog, Christopher decides to find out the cause of the dog's death. He records his findings, as he has decided that he will create a "murder mystery novel" of the situation. But like any murder mystery novel, nothing is as simple as it seems. Christopher runs into many difficult situations because of his disability. He again and again mentions how he admires Sherlock Holmes (a fictional detective), which gives me an understanding as to why he continues to look into Wellington's death even after his father makes him promise not to. Christopher's story seems so true and heartfelt and that makes the novel an entertaining read. The author, Mark Haddon, had me wanting to keep reading to find out what Christopher would get himself into next. Haddon shows how Christopher' s disability affects how he goes about solving the mystery. Christopher has difficulty in communicating or forming relationships with others, but he has a great visual memory and ability to understand difficult math. This book was required reading at my school, but it became more than something I had to read. Haddon showed how these disabilities affect the lives of not only the children diagnosed with them, but also those around them. The novel feels real because it was written from Christopher's point of view. For example, when Christopher explains that when he was little he didn't understand much about other people having minds, it gives the impression that he's a real person. I believe that teenagers sometimes aren't sensitive to kids with mental disabilities. I think that when people read this novel, they will have a better understanding of what people with mental disabilities and those around them have to deal with on a daily basis.
Answer: is unable to communicate with others well

Article: A new study links heavy air pollution from coal burning to shorter lives in northern China. Researchers estimate that the half-billion people alive there in the 1990s will live an average of 5 years less than their southern counterparts because they breathed dirtier air. China itself made the comparison possible: for decades, a now-discontinued government policy provided free coal for heating, but only in the colder north. Researchers found significant differences in both _ pollution of the air and life expectancy in the two regions. While previous studies have found that pollution affects human health, "the deeper and ultimately more important question is the impact on life expectancy," said one of the researchers, Michael Greenstone, a professor of environmental economics at Massachusetts Institute of Technology. "This study provides a unique setting to answer the life expectancy question because the(heating) policy dramatically changes pollution concentrations ,,,Greenstone 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 time periods," he said. The policy gave free coal for fuel boilers to heat homes and offices to cities north of the Huai Rivwhich divides China into north and south. It was in effect for much of the 1950-198,0 period of central planning, and, though discontinued after 1980, it has left a legacy in the north of heavy coal burning, which releases particulate 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 suspended particulates. In China, those are considered to be particulates that are 100 micrometers or less in diameter, sent out from sources including 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 life expectancies using death data from 1991-2000. They found that in the north, the concentration of particulates was 184 micrograms per cubic meteror 55 percent higher than in the south, and life expectancies were 5.5 years lower on average across all age ranges.
Answer: research in China finds air pollution shortened life expectancy
