Question: 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

Answer: A

Question: Article: Every day Yang Hongwei takes the bus home from work, staring silently at the European-style villas , luxury cars and twinkling lights from the shopping center that he sees through the window. Yang works for a software company in Zhongguancun. He dreams of such a life, away from poverty, and that hope has kept him in Beijing for three years since he graduated from university. Soon Yang squeezes his way off the bus to the reality of his life: his home--a 10-square-metre room that costs 550 yuan(81 US dollars) or about one-fifth of his salary in rent every month. It's very cold inside the house as it has no central heating system. He has to stand the long and cold winter. Determined to achieve his dream, Yang says he has changed jobs "numerous" times in the past three years and is considering quitting his present job. Yang's frustration over his life as a migrant is shared by many other graduates that have moved into big cities. Together they have come to be called the "ant tribe", a term created by Chinese sociologists to describe the struggles of young migrants, who, armed with their diplomas, flood to big cities in hopes of a better life only to put up with low-paying jobs and poor living conditions. They share every similarity with ants. They live in colonies in crowded areas. They're intelligent and hardworking, yet unknown and underpaid. The term, sociologists have said, also reflects their helplessness in a world governed by the law of the concrete jungle--only the strongest survive. A survey in Ant TribeII found nearly 30 percent of the "ants" are graduates of famous key universities--almost three times the percentage of 2009. Most have degrees in popular majors, such as medicine, engineering, economics and management. In addition, 7.2 percent of the "ants" have at least a master's degree compared to 1.6 percent in 2009. Most said the economic recovery did not really improve their financial situations, and 66 percent said their incomes fell short of their expectations, the survey also found. For two years, Lian Si, a post-doctoral fellow at the Center for Chinese and Global Affairs of Peking University, who has studied the phenomenon, led a team of more than 100 graduate students to follow the groups in university towns like Beijing, Shanghai, Guangzhou, Wuhan and Xi'an. Lian evaluates the total population of the "ant community" in major cities at one million across China, with about 100,000 found in Beijing alone. Lian predicts that an increasingly challenging job market will see the ant tribe growing further in number. Another 6.3 million graduates are expected to join migrant workers and other job hunters in what promises to be a fierce labour competition. The ant tribe's embarrassing living situations have become a serious social issue, and the government should develop "second-and-third-tier cities" to attract more graduates from big cities. However, "ants" expect more study and training opportunities in big cities, which keeps them in positive mindsets despite their situations. As in the case of Yang, he is optimistic about getting a new job soon, having received eight interview offers in a week after sending out his resume. The prospect of landing a higher-paying job keeps him hopeful of moving out of the slum district soon. The sooner the better.
