I'm taking a test and have to guess the right answer to the question after the article. Article: A purple tomato genetically engineered to contain nutrients more commonly seen in dark berries helped cancer in mice, British researchers said on Sunday. The finding, published in the journal Nature Biotechnology, the idea that plants can be genetically modified(changed) to make people healthier. Cancer-prone mice fed the modified fruit lived significantly longer than animals fed a standard diet with and without regular tomatoes, Cathie Martin and colleagues at the government-funded John Innes Center in Britain reported. "The effect was much bigger than we had expected." said Martin, a plant biologist. The study focused on anthocyanins,a type of antioxidant found in berries such as blackberries and blackcurrants that have been shown to lower risk of cancer, heart diseases and some neurological diseases. While an easy way to improve health, many people don't eat enough of these fruits, the researchers said. Using genes from the snapdragon flower, the researchers discovered they could get the tomatoes to make anthocyanins---- turning the tomato purple in the process. Mice genetically engineered to develop cancer lived an average of 182 days when they were fed the purple tomatoes, compared to 142 days for animals on the standard diet. "It is greatly encouraging to believe that by changing diet, or specific components in the diet. You can improve health in animals and possibly humans." Martin said in a telephone interview. The researchers warned that trials in humans are a long way off and the next step is to investigate( look into) how the antioxidants actually affect the tumors to promote better health. But the findings do support the formal research suggesting that people can significantly improve their health by making simple changes to the daily diet, other researchers said. "It's exciting to see new techniques that could potentially make healthy foods even better for us." said Doctor Lara Bennett, science information office at Cancer Research UK. " But it is too early to say whether anthocyanins obtained... Question: According to Dr. Lara Bennett, the effects of anthocyanins through diet on human being _ Options: A: are not certain now. B: have been proved C: are very harmful D: are hard to be tested

I'm taking a test and have to guess the right answer to the question after the article. Article: It's difficult not to become involved in gossip at work. After all, people like gossip and interesting bits of information: you only have to look at the number of celebrity-focused publications to realize that we have a huge appetite for discussing other people's lives. At work, however, this type of interaction is harmful and costly. It wastes time, damages reputations, promotes divisiveness , creates anxiety. Rumors often grow because people like to be "in the know." Knowledge is power, and that's why the people with the least amount of power in an organization can often be the ones to start and spread rumors. It can make them feel important if they're seen to know things that others don't. This knowledge is at the center of why and how rumors start and spread. Insufficient knowledge or incomplete information are often to blame. Consider these examples: *People don't know why a colleague was fired, so they make up a reason based on some limited knowledge or insignificant fact. "I saw John override the cash register the other day without a supervisor present. Maybe he stole some money and that's why he went." *People see a pattern of behavior between two individuals and they add their own explanation. "Joseph and Samantha spend a lot of time together after hours 'catching up on paperwork.' And just yesterday, they were sitting awfully close to each other in the meeting. I bet paperwork isn't all that's getting done after work!" These rumors are typical of the things you'll face at work, and they spread because of a lack of accurate information. So, the best way to fight rumors is with good communication. When you communicate well, your team knows what's happening, and they trust that you'll keep them informed. Good communication within your team also means that you will become aware of any rumors that are starting, and you'll be able to address them quickly and effectively. Question: What is the relationship between Joseph and Samantha in the eyes of the people spreading rumors? Options: A: They are lovers. B: They are work partners. C: They are rivals. D: They are old friends.
