Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Internet users can give websites a thumbs up or thumbs down in less than the blink of an eye, according to a recent study by Canadian researchers. Specifically, a positive or negative decision is made within one-twentieth of a second -- less than half the time it takes to blink.It is also about the time for users to read just one word on the website. In the study at the Carleton University in Ottawa, websites were flashed up on a screen for participants to view for 50 milliseconds, and then rated by the viewer. Later when the pages were viewed again for longer periods of time, the viewers' opinion were the same. The study was published in the March/April issue of the journal Behaviour & Information Technology. "It really is just a physiological response.If the first impression is negative, you'll probably drive people off," said Dr.Gitte Lindgard, the leading researcher, "So Web designers have to make sure they're not offending users visually." However, the results did not show how to win a positive reaction from users."When we looked at the websites that we tested, there is really nothing there that tells us what leads to dislike or to like," Dr.Lindgard said. Usually the appeal of a website is tied to color1, movement and interactivity .And while further research may offer more clues , personal taste would always be a limiting factor, according to Lindgard. "If the designs were _ to a set of principles, wouldn't we find an awful lot of similar houses, gardens, cars?" she said."We'd have no variety." Question: What might be the factor that leads to a negative first impression on a website? Options: A: Users' visual feeling. B: Users' physical fitness. C: Websites' contents. D: Websites' theme.
Answer: A

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: We all know that eating junk food can make us fat. However, a new study suggests that it can do more than that - it can also make us lazy, reported CBS News. In the study, researchers at the University of California, Los Angeles, US divided 32 female rats into two groups. The first group was fed a diet of healthy food such as corn and fish, while the second was given a diet of highly processed food rich in sugar, namely "junk food". Within three months, the rats in the second group were already much fatter than those on the healthy diet. And when researchers trained the rats to do simple tasks, they found even more differences between the two groups rather than weight. During the task - pushing a lever to receive a reward of sugar water - the rats on the junk food diet were found to be less willing to move, and they took longer breaks between each push than the lean rats did. "It is as if the rat is thinking 'This is too much work'," Aaron Blaisdell, leader of the study, told the Los Angeles Times. But what about the possibility that the fat rats were less passionate about getting sugar water because they were already eating lots of sugar in their daily diet? That's why researchers repeated the tests by rewarding fat rats with plain water when they were extremely thirsty. However, the results came out just the same. According to researchers, these differences suggest that junk food changed the chemistry in the rats' brains. The experiment didn't end _ . After six months, the rats' diets were switched, and the overweight rats were given a healthy diet for nine days. However, this change didn't help reduce their weight or improve their ability to perform tasks, which means the effects of their junk food diet persisted . "There's no quick fix," said Blaisdell. For a long time, we've believed that people become fat because they are lazy. But this study has proven the opposite to be true as well, which indicates that laziness and obesity are a "vicious cycle ". So, if you constantly feel tired, lacking any...
