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: Why does the author mention the 40 richest Americans' commitment in this passage? - To argue against offering sympathy. - To use it as an example to support his opinion. - To show their generosity to society. - To call on people to learn from them.
To use it as an example to support his opinion.

" Sit down, Julia Vassilyevna," I said."Let's settle our accounts. Although you most likely need some money, you stand on ceremony and won't ask for it yourself. Now then, we agree on thirty rubles a month..." " Forty." " No, thirty. I made a note of it. I always pay the governess thirty. Now then, you've been here two months, so..." " Two months and five days." " Exactly two months. I made a specific note of it. That means you have sixty rubles coming to you. Subtract nine Sundays... you know you didn't work with Kolya on Sundays, you only took walks. And three holidays..." Julia Vassilyevna flushed a deep red and picked at the flounce of her dress, but--- not a word. " Three holidays, therefore take off twelve rubles. Four days Kolya was sick and there were no lessons, as you were occupied only with Vanya. Three days you had a toothache and my wife gave you permission not to work after lunch. Twelve and seven---nineteen. Subtract...that leaves...hmm...forty-one rubles. Correct?" Julia Vassilyena's left eye reddened and filled with moisture. Her chin trembled; she coughed nervously and blew her nose, but---not a word. " Around New Year's you broke a teacup and saucer: take off two rubles. The cup cost more, it was an heirloom, but---let it go. When didn't I take a loss? Then, due to your neglect, Kolya climbed a tree and tore his jacket: take off ten. Also due to your heedlessness the maid stole Vanya's shoes. You ought to watch everything! You get paid for it. So, that means five more rubles off. The tenth of January I gave you ten rubles..." " You didn't " whispered Julia Vassilyevna. " But I made a note of it." " Well...all right." " Take twenty-seven from forty-one ---that leaves fourteen." Both eyes filled with tears. Perspiration appeared on the thin, pretty little nose. Poor girl! " Only once was I given any money," she said in a trembling voice, " and that was by your wife. Three rubles, nothing more." "... Question: The employer made all those criticisms about Julia Vassiliyevna's work because _ - she had neglected her duties. - he wanted to pay her as little money as possible. - he wanted to make her realize that she was being cheated and protest against it. - he wanted to make her feel miserable.
he wanted to make her realize that she was being cheated and protest against it.
