Article: What if it isn't a dog-eat-dog world? What if caring for a dog or for a mom with Alzheimer's makes you stronger and allows you to live longer? Researchers at the University of California, Berkeley are challenging our long-held belief that humans are born to be selfish. Darwin's theory of evolution by natural selection was misunderstood by his male followers, the researchers say. Rather than "every man for himself", Darwin believed that humans are successful as a species precisely because of our educational, selfless and sympathetic characteristics. Why has it taken so long for Darwin's central revelation to be properly understood? "We've had too many men in social science," Berkeley psychology professor Dacher Keltner told me in an interview. "Female scientists acknowledge that caring for people is part of human nature according to the research, which shows the human ability to care exists in our brains and nerve systems." In my bookPassages in Caregiving, I urge women who take the whole responsibility for taking care of an elderly parent or a sick relative to build a "Circle of Care". Reach out to your brothers and sisters, friends, neighbors and community volunteers to help you care, because no one can perform this overwhelming role alone. You will be as shocked as I to learn how the most selfless caregivers are rewarded with longer life. Sympathy is not a woman's word. In fact it makes all of us stronger under stress and more highly respected by our peers. For so long we have repeated the false saying "Nice guys finish last". But the 40 richest Americans committed to doing good by donating half their fortunes are _ . So here is my new explanation:Nice guys die last.
Question: InPassages in Caregiving, women are advised to _ .
Options: (A) share the responsibility of caring with others (B) take good care of themselves (C) learn how to live a longer life (D) help as many people as possible

Article: Of all the famous English writers, probably the best known is William Shakespeare. He was born in Stratford-upon-Avon in 1564 on April the 23rd. His father was an important man in town so Shakespeare had a good upbringing. Shakespeare probably went to school (although no records survive to prove this) but not university. He got married when he was 18 to Anne Hathaway and the couple had 3 children. Shakespeare wrote 38 plays and 154 sonnets (a sonnet is a kind of poem). He began working in his home town of Stratford but by 1592 was writing in London. He became rich enough to buy a house in the capital and one in Stratford. He wrote sad stories called tragedies, like Romeo and Juliet, funny stories or comedies, romantic stories and stories about historical figures such as Julius Caesar. Shakespeare died on his birthday in 1616, almost 400 years ago. But why is his work still popular today? His work looked at common human themes, such as betrayal, murder, lust, power, ambition and love. These themes are as much a part of human nature today as they were all those years ago and are the themes we see in modern soap operas and Hollywood films. Even though his theatre, The Globe, burned down in 1613 it was rebuilt in London in 1997 and you can still see his plays performed there today. Shakespeare's influence on the English language can still be felt today. We talk about "fair play", meaning honest behaviour but this phrase was first used by Shakespeare. He coined the phrase "you can have too much of a good thing". And it was Shakespeare who came up with the expression to disappear "into thin air" which we still use today when we lose something. Shakespeare's work has been translated into every major language in the world. And perhaps we'll still be as fascinated by his work 400 years from now as we've been for the last 400.
Question: How old was Shakespeare when he died?
Options: (A) 18. (B) 28. (C) 49. (D) 52.

Article: Peter loved to shop used articles. Almost a month ago, he bought popular word game that used little pieces of wood with different letters on them. As he was purchasing it, the salesgirl said, "Uh, look, the game box haven't even been opened yet. That might be worth some money. " Peter examined the box, and, sure enough, it was completely covered in factory-sealed plastic. And he saw a date of 1973 on the back of the box. "You should put that up for auction on the Internet, and see what happens."the salesgirl said. "Yes, you're right. People like something rare." Peter agreed, "I can't imagine there being very many unopened boxes of this game still around 40 years later." "Don't forget to tell me if you sell it." the salesgirl smiled. "No problem." Peter said. After he got home, Peter went online to several auction websites looking for his game. But he couldn't find it. Then he typed in the name of the word game and hit Search. The search result was 543 websites containing information about the changes of the game. Over the years, the game had been produced using letters in different sizes and game boards in different colors. He also found some lists of game fans looking for various versions of the game. Peter emailed some of them, telling them what he had. Two weeks later, Peter went back to the shop. "Hello. Do you still remember the unopened word game?" The salesgirl looked at him for a second, then recognized him and said, "Oh, hi!" "I've got something for you," Peter said. "I sold the game and made $1,000. Thank you for your suggestion." He handed her three $ 100 bills. "Wow!" the salesgirl cried out. "Thank you, I never expected it."
