[Q]: Article: At first all films were in black and white, but in 1932 the first color film was made. It proved as unpopular as making films had done in the late 1920's. It was not until 1938 that a full length color film was made, and the success of this film made producers everywhere change from black and white to color. This first full-length color film was translated into ten different languages and made Hollywood the main center( )of film industry In the early days of the cinema, other countries had also film industries. Very good films were made in Sweden, Britain, Russia and France. However, because Holleywood had so much money to spend, it kept its position as the world's most important film center. Film actors went to America because they knew they could get a lot of money for every film they made. In 1918 Charlie Chaplin (*)received $5 each day. However, life was not always easy for the film actors. Newspapermen followed them everywhere, and after Charlie Chapine married for the fourth time he became so unpopular with the American public that he had to leave the country and live in Europe.

[Q]: 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.
[A]: D

[Q]: Article: The current Ebola outbreak in western and central Africa has infected at least 3,069 people, including 1,552 dead, making it the largest outbreak in history. Ebola is a deadly virus --about 60 percent of people infected with it have died. How is Ebola doing its harm? When a person becomes infected with Ebola, the virus damages the body's immune cells, which defend against infection, said a researcher at Lancaster University. But if a person's immune system can stand up to this attack, then he is more likely to survive the disease. The patients that survive it best are those who don't get such a bad disadvantage in immune system. But if the body isn't able to get rid of this attack, then the immune system becomes less able to regulate itself. This means the immune system is more likely to run out of control, leading to a drop in blood pressure, multi-organ failure and eventually death. What are the common symptoms of the disease? Fever. Headache. Joint and muscle aches. Weakness. Diarrhea. Vomiting. Stomach pain. Lack of appetite. Chills. Rash. Redness in the eyes. Hiccups. Cough. Sore throat. Chest pain. Difficult breathing or swallowing. Bleeding inside and outside of the body. How to prevent the spread of Ebola? Ebola can be spread primarily via direct contact with patients, specifically the blood and fluids of an infected patient. We should avoid contact with infected patients and objects such as clothing, bedding, and needles used by them. Avoid areas where infections have been reported. For now, the disease has only been confirmed in central and West Africa, four cases in America and Europe. Avoid eating wild-caught bush meat. Researchers have suspected that the disease came to humans via animals, probably through the meat of primates . If you're in an area where the disease has been reported, avoid purchasing, eating, or handling wild game to stay on the safe side. Wear protective medical clothing if you're around infected patients. Extreme caution is necessary. Hospital workers must use masks, gloves, goggles, and gowns, which needed to be worn at all times if you're around infected patients. How Do People Survive Ebola? Doctors don't know for certain who will survive Ebola, and there is no specific treatment or cure for the disease. Although in the minority, some people do recover from infection. Our suggestions include: Maintain your electrolytes and body liquid. Sports drinks can be used. Monitor your blood pressure and control it if necessary. Dropping blood pressure may be a serious sign of infection. Breathe in an oxygen-rich environment. Quickly address any symptoms of infection. Be honest about when and where you're feeling pain.
