Example Input: Article: When my grandfather died, my 83-year-old grandmother, once so full of life, slowly began to fade. No longer able to manage a home of her own, she moved in with my mother, where she was visited often by other members of her large, loving family. Although she still had her good days, it was often hard to arouse her interest. But one chilly December afternoon three years ago, my daughter Meagan, then eight, and I were visiting her, when she noticed that Meagan was carrying her favorite doll."I, too, had a special doll when I was a little girl," she told a wide-eyed Meagan. "I got it one Christmas when I was about your age. I lived in an old farmhouse in Maine, with Mom, Dad and my four sisters, and the very first gift I opened that Christmas was the most beautiful doll you'd ever want to see." "She had an exquisite(,), hand-painted face, and her long brown hair was pulled back with a big pink bow. Her eyes were blue, and they opened and closed. I remember she had a body of kidskin, and her arms and legs bent at the joints." GG's voice dropped low, taking on an almost respectful tone. "My doll was dressed in a pretty pink gown, decorated with fine lace. ... _ -- my parents must have had to sacrifice so much to afford it But how happy I was that morning!" GG's eyes filled and her voice shook with emotion as she recalled that Christmas of long ago. "I played with my doll all morning long. And then it happened. My mother called us to the dining room for Christmas dinner and I laid my new doll down gently on the hall table. But as I went to join the family at the table, I heard a loud crash." "I hardly had to turn around -- I knew it was my precious doll. And it was. Her lace skirt had hung down from the table just enough for my baby sister to reach up and pull on it. When I ran in, there lay my beautiful doll on the floor, her face smashed into a dozen pieces. She was gone forever." A few years later, GG's baby sister was also gone, she told Meagan, a victim of pneumonia . Now the tears in her eyes spilled over -- tears, I knew, not only for a lost doll and a lost sister, but for a lost time. Subdued for the rest of the visit, Meagan was no sooner in the car going home than she exclaimed, "Mom, I have a great idea! Let's get GG a new doll for Christmas. Then she won't cry when she thinks about it." My heart filled with pride as I listened to my sympathetic little daughter. But where would we find a doll to match GG's fond memories? Where there's a will, as they say, there's a way. When I told my best friends, Liz and Chris, about my problem, Liz put me in touch with a local doll-make. From a doll supply house I ordered a long brown hair and a kidskin body to copy the outfit GG had so lovingly described. Liz volunteered to put the doll together, and Chris helped me make the doll's outfit. Meagan wrote the story of the lost doll by giving examples. Finally our creation was finished. To our eyes it was perfect. But there was no way it could be exactly like the doll GG had loved so much and lost. Would she think it looked anything like it? On Christmas Eve, Meagan and I carried our happily packed gift to GG, where she sat surrounded by children, parents, aunts, uncles and cousins. "It's for you," Meagan said, "but first you have to read the story that goes with it." GG no sooner got through the first page than her voice cracked and she was unable to go on, but Meagan took over where she left off. Then it was time to open her present. I'll never forget the look on GG's face as she lifted the doll and held it to her chest. Once again her tears fell, but this time they were tears of joy. Holding the doll in her frail arms, she repeated over and over again, "She's exactly like my old doll, exactly like her." And perhaps she wasn't saying that just to be kind. Perhaps however impossible it seemed, we had managed to produce a close copy of the doll she remembered. But as I watched my eight-year-old daughter and her great-grandmother examining the doll together, I thought of a likelier explanation. What GG really recognized, perhaps, was the love that inspired the gift. And love, wherever it comes from, always looks the same.
Answer: she was not able to live on her own due to her weakness
Example Output: GG moved in with her daughter because _ .

Example Input: Article: Back in old times, people had little knowledge about the universe and nature. Things we now consider to be common sense were mysteries to our ancestors. Over the years, major breakthroughs have been made in science and many phenomena have been explained. But still, there are always questions we can't yet answer, and The Guardian has listed some of them. 1. What makes us human? Just looking at your DNA won't tell you - human DNA is 99 percent _ to that of the chimpanzee and, believe it or not, 50 percent identical to a banana's! A lot of the things we once thought were unique about us - language and tool use, recognizing ourselves in the mirror and so on - have since been seen in other animals. Perhaps it's our culture that makes the difference or maybe our ability to use fire. It's also possible that our capacity for co-operation and our trading skills are what make us unique. 2. Why do we dream? Given the fact that we spend around a third of our lives sleeping, shouldn't we know everything about it? Unfortunately, scientists are still searching for a complete explanation of what happens when we sleep and why we dream. Austrian psychologist Sigmund Freud believed dreams were the expressions of wishes that we can't fulfill in our real lives. Others have wondered whether dreams are just random "noise" coming from a sleeping brain. 3. Could we someday live forever? Apart from accidents, most people die because of diseases that can be treated and aging. And since many diseases, such as diabetes and cancer, are diseases of aging, treating aging itself could be the key to extending our lives. Our knowledge of what causes us to age - and what allows some animals to live longer than others - is expanding rapidly. And though we haven't quite worked out all the details, we've worked out some pieces of the puzzles such as DNA damage and metabolism , which are all leading to the invention of drugs that can slow down the aging process. If we're lucky enough to lengthen our lives, we might even get to see the day when all of these questions are answered.
Answer: to explain what were once mysteries to our ancestors

Example Input: Article: One of the United States' social problems is the breakdown of the two-parent family. Today, millions of American children grow up without fathers. Too often, these children lack the love and help they badly need and which they would ordinarily receive from not one but two parents. In the old days, American parents placed the needs of their children above their own. At present, however, nearly one half of all new marriages end in divorce, with often troubling results for their children. Worse, every year, thousands of teenage, unmarried Americans become mothers outside marriage, with generally terrible results for the mothers and children alike and for American society more generally. However, Chinese continue to value whole marriages. This is not to say that Chinese marriages are all perfect. They certainly are not, judging from increasing rates of divorce and extramarital affairs-but the willingness of Chinese to set aside their own needs and stay together for the sake of the children is admirable and worthy of study. Families, in whatever form they may take, are important to Americans. If one was to ask a group of Americans what is the dearest to them, the majority would say"family".And yet, so many Americans spend much more time at work, that is, beyond the formal forty-hour work week-than they do with their own families. Obviously, the USA is one of the most powerful in the world, owing in large measure to"workaholism" . It seems to me that Chinese generally find a better balance between work and family needs than many Americans do. I don't see the number of workaholics in China that I do in the United States(or American organizations in China).Instead, average Chinese usually head home right after work(in the office or field),have meals together, and spend time with their family members. What's more, Chinese try to make more time for grandparents, uncles, aunts and cousins than many Americans; in many cases, multigenerational families live together. Of course, like many facts of Chinese society, this is all changing; increasing numbers of"New Chinese"are working longer hours and spending less time with their families than ever before. Still, while Americans do value their loved ones, I think we have something to learn from the Chinese about finding the proper balance between work and family.
Answer: there is something about family for Americans to learn from China
