PROBLEM: Article: The sharing economy has grown in recent years to include everything from apartment sharing to car sharing to community tool sharing. Since 2009, a new form of sharing economy has been emerging in neighborhoods throughout the US and around the world---- Little Free Library. The libraries are boxes placed in neighborhoods from which residents can withdraw and deposit books. Little Free Libraries come in all shapes and sizes. Some libraries also have themes, focusing on books for children, adults, or tour guides. In 2009, Tod Bol built the first Little Free Library as a gift to his mother, who was a devoted reader. When he saw the people of his community gathering around it, exchanging conversation as well as books, he knew he wanted to take his simple idea further. "I think Little Free Libraries open the door to conversations we want to have with each other," Bol said. Since then, his idea has become a movement, spreading from state to state and country to country. According to Little FreeLibrary.org, there are now 18,000 of the little structures around the world, located in each of the 50 US states and 70 countries in Europe, Africa and Asia. The Internet has helped to spread Little Free Libraries. But an Atlantic article says the little structures serve as a cure for a world of e-reader downloads. The little wooden boxes are refreshingly physical and human. For many people, the sense of discovery is Little Free Libraries' main appeal. "A girl walking home from school might pick up a graphic novel that gets her excited about reading; a man on his way to the bus stop might find a volume of poetry that changes his outlook on life," says the Atlantic article. "Every book is a potential source of inspiration".
Question: How do Little Free Libraries get their books?
Options: (A) The communities bought them. (B) Tod Bol donated them. (C) US government provided them. (D) Citizens shared them.

SOLUTION: D

PROBLEM: 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

SOLUTION: A

PROBLEM: Article: Dear Daddy, You've been gone for six years and I've had time to think. Now I'm ready to write this letter to you. For a long time after Mom died, I thought I liked her more because I didn't like your attitude and I thought that her softer side was more desirable. In my 15-year-old's mind, I thought you could have stopped my mother from drinking herself to death. Instead, you were off playing tennis and working. Later, I realized that no one could make someone stop drinking. Support is important, but at the end of the day, it is a choice. You were just doing your best. What I have learned is that I am much like you. You taught me self-confidence. I know if I am prepared to work hard enough for something, I will be successful. This is no small thing. What I've realized since you died is that you were always there for me. You fought to ensure that I got my place on the Quebec badminton team that I had earned. When I got divorced , you came up to see if I had what I needed to take care of the boys and you paid off my car. You taught me not to spend money I don't have. I've always kept to that rule. It has served me well. We always had a good home to live in, nice vacations, and everything we needed and most of what we wanted. You were not a perfect parent and neither am I. My children are much more thankful than I ever was. I am thankful that I had you as my dad. I am still Daddy's girl and I am proud of it.
