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: The first chocolate was eaten by people in South America hundreds of years ago. In those days, the people did not really eat chocolate. They used the cocoa bean to make a chocolate drink and they enjoyed it very much. Many years later, the cocoa bean was brought to other countries and people came to love the taste of chocolate. In 1824, John Cadbury opened a small shop in Britain. One of the things he sold was chocolate drink. In 1831, he opened a factory to make chocolate drink. He wanted to encourage people to drink chocolate instead of other drinks. A few years later, a man called Joseph Fry found a way to make chocolate instead of only drinking it. But at that time chocolate was very expensive and only the rich people could buy it. Later, ad more and more chocolate bars were produced and sold, it became cheaper. However, at first only plain chocolate (a kind of chocolate without milk and with very little sugar) was produced. Milk chocolate came later and this was made by adding milk to the chocolate. The first milk chocolate bar was made in Cadbury's factory in 1897. Their most famous chocolate, Cadbury's Milk Bar, was made in 1905, It has been the most popular chocolate in Britain and around the world for over 100 years. The Cadbury factory is still in Britain and the chocolate produced there is eaten all over the world. Every year, thousands of visitors visit the factory in order to see how chocolate is made.
