Article: A healthy amount of sunshine may be the secret to staying young. British scientists have discovered. Vitamin D is produced naturally by the skin in response to(...) sunlight and may help to slow the ageing process and protect against heart disease, according to the study. Researchers from King's College London studied 2,160 women aged between 18 and 79, looking at their telomeres--- a biological marker of ageing found in DNA. As people get older, their telomeres get shorter and they become more susceptible to certain illnesses. But the study found women with high levels of vitamin D had comparatively longer telomeres--- a sign of being biologically younger and healthier. The study suggests vitamin D may help to slow down the ageing process of DNA, and therefore the ageing process as a whole. Lead researcher Dr Brent Richards said, "These results are exciting because they show for the first time that people who have higher levels of vitamin D may age more slowly than people with lower levels of vitamin D." This could help to explain how vitamin D has a protective effect on many ageing related diseases, such as heart disease and cancer." Professor Tim Spector, a co-author of the report, added, "Although it might sound absurd , it's possible that the same sunshine which may increase our risk of skin cancer may also have a healthy effect on the general ageing process." Vitamin D made by the action of sunlight on the skin accounts for 90 percent of the body's supply, but lower levels can also be got through food such as fish, eggs and breakfast cereals . Other studies have suggested the vitamin plays a key role in protecting against cancer and heart disease. Question: A certain amount of sunshine helps people stay young because _ . Yes or no, is the answer "vitamin D may help to slow the ageing process"?

No

Article: For centuries Stonehenge has mystified and enraptured archaeologists and visitors. So maybe it is not surprising that another monumental wonder from prehistory has been overlooked for so long - even though it is just a mile away. Experts have discovered an 'extraordinary' line of giant stones that dates back more than 4,500 years. The area around Stonehenge is littered with prehistoric sights but the 90 or more stones, lying 3ft underground, have only just been discovered by sophisticated radar equipment towed by radar equipment. The buried monoliths are each up to 15ft tall. Instead of being arranged in a circle as they are at Stonehenge, it is thought they once formed a long standing line. 'We are looking at one of the largest stone monuments in Europe and it has been under our noses for something like 4,000 years,' said Professor Vince Gaffney, from the University of Bradford, one of the archaeologists leading the research. 'It's truly remarkable. We don't think there's anything quite like this anywhere else in the world. This is completely new and the scale is extraordinary." Prof. Gaffney believes the stones may have been planted by the same people who built Stonehenge, but he doubts whether there is a direct link between the two monuments. These stones were placed along a steep slope, cut into a natural dry valley to form a C-shaped feature. Precisely why the stones were put there remains a mystery. The archaeologists believe that at some stage the stones were pushed over. This was not done to damage the monument but rather to preserve whatever it was about the stones that seemed so important. "There was a transformation in the landscape that we do not understand," Prof. Gaffney said. "The stones had significance. These were special places. Societies were organized, as with the great cathedrals, to create these things." Question: Which sentence is TRUE according to the passage? Yes or no, is the answer "The stones might serve for a certain purpose."?
(Answer)
No

Article: Mr. Patrick was new to the school and to us. Even though he was a great teacher, he seemed rather like a character out of a horror movie. He didn't look that bad, but somehow, he looked extremely scary to me. Some kids began to believe that he was a murderer or a ghost; some believed he was mad and a few believed that he might have suffered a lot in his life. I was one of those 'few'. One day I gathered up my courage and headed towards the school garden. He was, as usual, sitting on a bench alone. I breathed heavily a few times and then walked towards him. "How are you?" I asked with my voice crackling. He managed to say, "Fine." "Well, good to know," I tried to be happy. "Hmmm..." was all I heard. "What's up with you?" then seeing a puzzled look on his face, I tried to be more formal and respectful. "I mean, why aren't you like all other people in the school? Why are you always so quiet and sad? Why..." "No dear, some things are better left unsaid," he said gloomily. "Oh no sir, nothing is better left unsaid. If you want to share your feelings with me and reduce the pain of your heart, you are free to do so. I promise I will never ever tell anyone." "With you? You are just a little girl; what will you understand?" I was somehow offended but still I managed to persuade him, "So what, Sir? You see, if you tell me your problem, you will have a light heart and you will have the feeling that someone somewhere cares about you." "Oh okay, that was a very nice belief indeed; let's take a walk and I will let you know everything." Soon after our little talk, there was a visible change on his face. Later that day in the class, there was a smile on his face. Question: While walking towards Mr. Patrick in the school garden, the author felt _ . Yes or no, is the answer "nervous"?
(Answer)
Yes
