Article: Caffeine not only gives us a daily jump start, but new research suggests it also can strengthen long-term memory. According to the US Food and Drug Administration, nearly 90 percent of people worldwide consume about 200 milligrams of caffeine each day. That' s equivalent to about one strong cup of coffee a day. Writing in " Nature Neuroscience" , Johns Hopkins University researchers say their findings show that caffeine strengthens certain memories for up t0 24 hours after being taken in. " We've always known that caffeine has cognitive-enhancing effects , but its ,particular effects on strengthening memories and making them resistant to forgetting has never been examined in detail in humans, " said senior author of the paper Michael Yassa. " We re- port for the first time a specific effect of caffeine on reducing forgetting over 24 hours. " Conducting a double-blind trial, the researchers worked with a test group of people who didn't regularly consume caffeinated products. Five minutes after studying a series of images, the test subjects were given either a placebo or a 200-milligram caffeine tablet. To check the caffeine levels of their test subjects, the research team took saliva samples from them before they took their tablets and again one, three and 24 hours after- wards. Both groups of test participants ( those who took the placebo and those who took the caffeine tablet) were tested the following day to see if they could recognize the images they' d seen the previous day. The test included showing the test subjects another series of images that included some new images , those that were shown the previous day, as well as other images that were similar, but not the same as those they had viewed earlier. The researchers found that more members of the group who were given the caffeine tablets were able to correctly identify some of the new images as " similar" to previously viewed images rather than incorrectly identifying them as the same. "We also know that caffeine is associated with... Question: The purpose of the new research is Yes or no, is the answer "to examine caffeine ' s memory-strengthening effects in detail"?

Article: When asked to point out one or two things that are most important to themselves, many put friends ahead of homes, jobs, clothes and cars. A true friendship carries a long history of experience that determines who we are and keeps us connected. It is a treasure we should protect. Unfortunately, the better friends you are, the more probably you'll have disagreements. And the result can be what you don't want--an end to the relationship. The good news is that most troubled friendships can be mended. First, don't let your pride get in your way. Most of us can forgive each other when differences are brought out in the open. Second, apologize when you're wrong -- even if you've been wronged. Over the course of a friendship, even the best people make mistakes. Sometimes, it may be best if the _ takes the lead and apologizes. When you apologize, give your friend a chance to admit that he has been wrong. Third, see things from your friend's point of view. And finally, accept that friendships change as our needs and lifestyle change. Making friends can sometimes seem easy. The hard part is keeping the connections strong during the natural ups and downs that have an effect on all relationships. My suggestion: consider friendship as an honor and a gift, and worth the effort to treasure and nurture . Question: What should we do if we follow the author's second suggestion? Yes or no, is the answer "Make an apology first."?
**Answer**
No

Article: Visiting Balboa Island, in sunny southern California, proved an exciting experience that I will never forget. I had never been to Balboa Island, even though it is only about an hour from my home in northern San Diego. Our first stop was for a specialty called a "Balboa Bar". It is a famous chocolate covered ice cream on a stick, created many years ago. As we drove along the streets toward the boat, I also saw some interesting buildings that stood for many years. Many of the building designs seemed like dollhouses and someone in our group said that the style was called, Victorian. After we parked our car on one of the streets, we got on the boat sailing to Balboa Peninsula. As I looked around the boat, I saw a bird flying very close to the water and our boat. A little girl near the boat' s edge jumped out to touch it and shockingly fell into the water! Her dad, who stood nearby, jumped in after her at once and everyone on the boat ran to help. The boat's engine stopped and both father and daughter got saved with the help of people on the boat. On Balboa Peninsula my family and I went to various shops, especially for food! We saw a restaurant at the very end. We enjoyed our lunch there, at the first Ruby's Diner ever opened in southern California. Although I have been to other restaurants of this popular chain , being at the very first is a great memory. On our way back to Balboa island we stopped at the huge Ferris Wheel, bought some sugars and played games. It was an exciting afternoon walking around on Balboa Island. I look forward to returning soon to spend some time on the beach again or maybe even to try fishing! Question: What did the author do on Balboa Island? Yes or no, is the answer "He walked along the beach."?

No

Article: Tu Youyou has become the first Chinese woman to win a Nobel Prize, for her work in helping to create an anti-malaria medicine. The 84-year-old's route to the honour has been anything but traditional. In China, she is being called the "three nos" winner: no medical degree, no doctorate, and she's never worked overseas. In 1967, malaria, a then deadly disease, spread by mosquitoes was _ Chinese soldiers fighting Americans in the jungles of northern Vietnam. A secret research unit "Mission 523 "was formed to find a cure for the illness. Two years later, Tu Youyou was instructed to become the new head of "Mission 523". "Mission523" read ancient books carefully for a long time to find historical methods of fighting malaria. When she started her search for an anti-malarial drug, more than 240,000 compounds around the world had already been tested, without any success. Finally, the team found a brief reference to one substance, sweet wormwood , which had been used to treat malaria in China around 400 AD. The team took out one active compound in wormwood, and then tested it. But nothing was effective until Tu Youyou returned to the original ancient text. After another careful reading, she changed the drug recipe one final time, heating the compound without allowing it to reach boiling point. After the drug showed promising results in mice and monkeys, Tu Youyou volunteered to be the first human recipient of the new drug. " In any case, Tu Youyou is consistently praised for her drive and passion. One former colleague. Lianda Li, says Ms Tu is "unsociable and quite straightforward", adding that "if she disagrees with something, she will say it." Another colleague, Fuming Liao, who has worked with Tu Youyou for more than 40 years, describes her as a "tough and stubborn woman". Stubborn enough to spend decades piecing together ancient texts, she applies them to modern scientific practices. The result has saved millions of lives. Question: Which of the following statements is true? Yes or no, is the answer "Over 240,000 compounds were proved ineffective before Tu's seareh."?
**Answer**
Yes
