Ques: Article: Researchers in the US say they might have discovered how to fight against and even _ some processes of ageing, at least in mice. Injecting the blood of young mice into the older ones improved their brainpower, a study found. Scientists at Stanford University plan to carry out trials in people in the hope that new treatments for dementia can be developed. "There are factors present in blood from young mice that can recharge an old mouse's brain so that it functions more like a younger one,"says Dr. Tony from Stanford University School of medicine. In the study published in Nature Medicine, mice aged 18 months were given injections of the blood taken from mice aged 3 months. The injected mice performed better on memory tests than mice of the same age that had not been given the blood. Dr. Tony said it was not known whether the same was true of humans, but a trial was planned. A research center in UK said the treatment restored certain aspects of learning and memory in mice, but was of unknown importance to humans. The research, while very interesting, did not test the type of brain damage that was seen in dementia, which is not a necessary consequence of ageing. Meanwhile, two similar studies by a separate team have thrown more light on how young blood may benefit the old, in mice at least. A substance in the blood of mice previously shown to have an anti-ageing effect on heart muscle also improved brain cells, according to a Harvard team. The research, published in Science, found the blood factors encouraged the growth of brain cells in old mice, and restored their sense of smell. The same chemical also improved muscle power of aged mice, the researchers found. Question: What's the author's attitude to the anti-ageing studies? Yes or no, is the answer "objective"?
Ans: No

Ques: Article: Some people surveyed tasted the sweet, salty, and crunchy together with other tastes of food as they listen to different noises. It shows that louder noises reduced the reported sweetness or saltiness of food while increasing the measure of crunchiness . It may go some way to explain why airline food is widely complained about by both the workers and passengers. Andy Woods, a researcher, said, "It's a general opinion that plane foods aren't fantastic, but I'm sure airlines do their best, so we wondered if there were other reasons. One thought was that perhaps the background noise may have an effect. NASA gives their space explorers very strong-tasting foods, because for some reason, they can't taste food that strongly--again, it may have something to do with the background noise." In a study, 48 people were fed sweet foods or salty ones, while listening to nothing or noise through earphones. Meanwhile they rated the foods. In noisier settings, foods were rated less salty or sweet than they were when it was silent, but were rated crunchier. "The evidence shows that if the background noise is loud, your attention might be drawn to that, away from the food." Dr. Woods said. "We are still at an early stage of progressing and this is a rather small study to really draw definitive conclusions from," Dr Woods said, "but they suggest that restaurants could well adapt their choice of food for a given environment." Also in the group's findings there is the suggestion that the overall satisfaction with the food is also related to the degree to which people like what they are hearing. Question: What would be the best title for the text? Yes or no, is the answer "Background noise affects the taste of foods"?
Ans: No

Ques: Article: Animal experts in Croatia say a bear has learned how to trick people to let him in by knocking at the door. They believe the 220- kilogram brown bear probably learned the trick while nudging a door to get it to open. Experts have a guess that the nudging was mistaken by the owners for knocking and that the bear, pleased by the result, repeated the trick. The Loknar family from Gerovo in western Croatia said the bear had knocked at their door three times and they were now refusing to answer the door. ''We jumped out of the window as he came in through the door and went into the kitchen to take some food for the first time." Mum Nevenka Loknar told a reporter from a local newspaper. "I opened the door and saw him standing there and I didn't believe my eyes at first, then I ran for it as he walked in as if _ was the most normal- thing in the world." Bears are a common thing in the woods around here, but no one has ever heard of a bear that knocks at the door. Mum Nevenka Loknar said, "The bear is so intelligent. It's incredible. We've tried to put up lots of obstacles to stop him coming in, like a wire fence but he still gets through. I wouldn't be surprised if he knew how to use wire cutters." Question: Mum Nevenka Loknar was surprised that the bear _ . Yes or no, is the answer "was clever at getting through the obstacles"?
Ans:
No
