Question: Article: 1826, a Frenchman named Niepce needed pictures for his business .But he was not a good artist.So he invented a very simple camera .He put it in a window of his house and took a picture of his garden .That was the first photo. The next important date in the history of photography was 1837. That year, Daguerre, another Frenchman, took a picture of his studio. He used a new kind of camera and a different processs. In his pictures, you could see everything very clearly, even the smallest details. This kind of photograph was called a daguerreotype. Soon, other people began to use Daguerre's process. Travellers brought back daguerreotypes from all around the world. People photographed famous buildings, cities and mountains. In about 1840, the process was improved. Now photographers could take pictures of people and moving things. The process was not simple. The photographers had to carry lots of film and processing equipment. But this did not stop the photographers, especially in the United States, where from the 1840s daguerreotype artists were popular in most cities. Mathew Brady was a well-known American photographer. He took many pictures of famous people. The pictures were unusual because they were very life-like and full of personality. Brady was also the first person to take pictures of war. His 1862 Civil War pictures showed dead soldiers and ruined cities. They made the war seem more real and more terrible In the 1880s, new inventions began to change photography. Photographers could buy film readymade in rolls. So they did not have to make the film immediately. They could bring it back to their studios and develop it later, meaning that they did not have to carry lots of equipment. And finally, the invention of the small handheld camera made photography less expensive. With the small camera, anyone could be a photographer. People began to use cameras just for fun. They took pictures of their families, friends and favourite places. They called these pictures "snapshots". Photographs became very popular in newspapers in the 1890s. Soon magazines and books also used documentary photographs. These pictures showed true events and people. They were much more real than drawings. Photography had turned into a form of art by the beginning of the 20th century. Some photographs were not just copies of the real world. They showed ideas and feelings, like other art forms.

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
