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... Question: During the first three months of the experiment by researchers at the University of California, _ . Options: A: rats from the healthy diet group ate nothing but corn and fish B: rats on the junk food diet ate more than those on healthy diet C: rats on the healthy food diet performed better at simple tasks than those on the junk food diet D: rats on the junk food diet seemed uninterested in sugary food

I'm taking a test and have to guess the right answer to the question after the article. Article: It was the small hours of the morning when we reached London Airport. I had rung London from Amsterdam, and there was a hired car to meet, but there was one more unfortunate happening before I reached my flat. In all my travels I have never, but for that once, been required by the British customs to open a single bag or to do more than state that I carried no goods liable to duty, or rather, to declare. It was, of course, my fault; the extreme tiredness and nervous tension of the journey had destroyed my normal state of mind. I was, for whichever reason, so tired that I could hardly stand, and to the question, "have you read this?" I replied with extreme foolishness, "Yes, hundreds of times." "And you have nothing to declare?" "Nothing." "How long have you been out of this country?" "About three months." "And during that time you have acquired nothing?" "Nothing but what is on the list I have given you." He seemed momentarily at a loss, but then he attacked. The attack, when it came, was completely unexpected. "Where did you get that watch?" I could have kicked myself. Two days before, when playing water games with a friend in the bath, I had forgotten to take off my ROLEX OYSTER, and it had, not unnaturally, stopped. I had gone into the market and bought, for no more than ten pounds, an ugly time piece that made a strange noise. It had stopped twice, without any reason, during the journey. I explained, but I had already lost face. I produced my own watch from a pocket, and added that I should be grateful if he would _ the replacement. "It is not a question of confiscation; you will have it," he said, "there is a fine for failing to declare dutiable goods. And now may I please examine that Rolex?" It took another quarter of an hour to persuade him that the Rolex was not contraband ; then he began to search my luggage. Question: What do you think is the tone of the story? Options: A: Serious. B: Critical. C: Humorous. D: Objective.
