Article: "Hey, do you know what? Today is May Day!" my sister announced. "Do you remember the May Day baskets we used to make with colored paper and paste?" I recalled that my sisters and I would run around our neighborhood delivering the baskets brimming with spring flowers. We would place them on a doorstep, knock on the door, then run away. It was delightful to look around a bush and watch our friends open their doors and pick up the colorful gift,wondering who had left it out for them. I clearly remember the May Day of the year that I was in fifth grade. That year I was faced with a challenge involving one of my dearest friends. She lived right across the road from our family, and we had walked together to school nearly every day since first grade. Her interests were starting to change from the interests that we had shared together. A new family had recently moved into our small town,and Pam was spending more and more time at their house. When my mother asked me if I was going to take a May Day basket to Pam's house, I responded angrily, "Absolutely not!" My mom told me that I would have many other friends throughout my lifetime. "But Pam was my very best friend ever," I cried. Mom wiped away my tears and told me that circumstances change and people change. She explained that one of the greatest things friends can do is to give each other a chance to grow, to change and to develop into what we want to be. And sometimes that would mean that friends would choose to spend time with other people. I could express my forgiveness by giving her a May Day basket. It was a hard decision, but I made an extra special basket of flowers with lots of yellow because that was Pam's favorite color. I asked my two sisters to help me deliver my basket of forgiveness. As we watched from our hiding place, Pam picked up the flowers, and said loudly enough for us to hear, "Thank you, Susie, I hoped you wouldn't forget me!". Question: What lesson can we learn from the story? Yes or no, is the answer "We can't expect too much from our friends."?
No

Article: Plants are flowering faster than scientists predicted in reaction to climate change,which could have long damaging effects on food chains and ecosystems. Global warming is having a great effect on hundreds of plant and animal species around the world,changing some living patterns,scientists say. Increased carbon dioxide (CO2)in the air from burning coal and oil can have an effect on how plants produce oxygen,while higher temperatures and changeable rainfall patterns can change their patterns of growth. "Predicting species' reaction to climate change is a major challenge in ecology,"said the researchers of several U.S. universities.They said plants had been the key object of study because their reaction to climate change could have an effect on food chains and ecosystem services. The study,published on the Nature website,uses the findings from plant life cycle studies and experiments across four continents and 1,634 species.It found that some experiments had underestimated the speed of flowering by 8.5 times and leafing by 4 times. "Across all species,the experiments under-predicted the speed of the advance--for both leafing and flowering -- that results from temperature increases,"the study said. The design of future experiments may need to be improved to better predict how plants will react to climate change,it said. Plants are necessary for life on the Earth.They are the base of the food chain,using photosynthesis to produce sugar from carbon dioxide and water.They let out oxygen which is needed by nearly every organism on the planet. Scientists believe the world's average temperature has risen by about 0.8 degC since 1900,and nearly 0.2 degC every ten years since 1979. So far,efforts to cut emissions of planet-warming greenhouse gases are not seen as enough to prevent the Earth heating up beyond 2 degC this century-- a point scientists say will bring the danger of a changeable climate in which weather extremes are common,leading to drought,floods,crop failures and rising sea levels. Question: Scientists pay special attention to the study of plants because . Yes or no, is the answer "they are very important in the food chains"?
Yes

Article: If you know exactly what you want, the best way to get a job is to get specialized training. A recent survey shows that companies like graduates in such fields as business and health care who can go to work immediately with very little on-the-job training. That's especially true of booming fields that are challenging for workers. At Cornell's School of Hotel Administration, for example, bachelor's degree graduates get an average of four or five job offers with salaries ranging from the high teens to the low 20s and plenty of chances for rapid advancement. Large companies, especially, like a background of formal education coupled with work experience. But in the long run, too much specialization doesn't pay off. Business, which has been flooded with MBAs, no longer considers the degree an automatic stamp of approval. The MBA may open doors and command a higher salary initially, but . As further evidence of companies gradually losing faith in specialized degrees, Michigan State's Scheetz mentions a pattern in hiring practices. Although companies tend to take on specialists as new hires, they often seek out generalists for middle and upper-level management. "They want someone who isn't constrained by details to look at the big picture," says Scheetz. This sounds like a formal statement that you approve of the liberal-arts graduates. Time and again labor-market analysts mention a need for talents that liberal-arts majors are assumed to have: writing and communication skills, organizational skills, open-mindedness and adaptability, and the ability to analyze and solve problems. David Birch, manager of the Boston Red Sox, claims he does not hire anybody with an MBA or an engineering degree, "I hire only liberal-arts people because they have a less-than-canned way of doing things," says Birch. For a liberal-arts degree, students focus on some basic courses that include literature, history, mathematics, economics, science, human behavior--plus a computer course or two. With these useful and important courses, you... Question: By saying "...but the effect of a degree washes out after five years"(Para 2), the author means _ . Yes or no, is the answer "an MBA degree does not help in the future promotion"?
Yes
