I'm taking a test and have to guess the right answer to the question after the article. Article: If you bought some candy months ago but never ate it, how can you tell whether it's still safe to eat? The easiest way is to check the "expiration date " printed on the wrapper. If that date has already passed, you're likely to throw the candy away. But is that really necessary? According to a new report from the US Natural Resources Defense Council (NRDC), tons of food is wasted each year, largely because people don't fully understand what expiration dates, or "use-by dates", actually mean. Food dating was introduced in 1970s because customers wanted more information about the things that they were eating. When they first showed up, use-by dates were only supposed to indicate freshness because producers wanted their products to be tasted in their best conditions. But the truth is that these dates aren't related to the risk of food poisoning or food-born illness, according to Time News. However, most customers misinterpreted use-by dates and related them to the safety of the food, and they still largely do now. Eggs, for example, can still be eaten three to five weeks after purchase even though the use-by date is much earlier. When their use-by dates pass, strawberry juice may lose its red color and biscuits may lose their crunch , but they are not harmful. "It's a confusing subject, the difference between food quality and food safety," said Jena Roberts, vice president of National Food Lab, a US food testing company. "Even in the food industry I have colleagues who get confused." This is why scientists are calling for a standard explanation to be printed following the use-by dates. "We want this to be clearly communicated so customers are not misinterpreting the date and contributing to a lot of waste," said Dana Gunders, a staff scientist with the NRDC. But this won't be a mistake that is easy to correct since people have believed it for so long. Another problem is that the quality levels of different foods change differently-some are still eatable long after their use-by date while others are not. As a... Question: Scientists are calling for a standard explanation to be printed together with the use-by dates because _ . Options: A: Most consumers often misunderstand use-by dates B: use-by dates are not helpful or reliable C: more consumers get worried about food safety D: the quality level of different foods changes differently

I'm taking a test and have to guess the right answer to the question after the article. Article: Who cares if money can't buy you love? But it can still be your best friend forever. That's one of the surprising findings in a new research paper, "The Power of Money", published in me journal Psychological Science. Like any best friend forever, money demonstrated to researchers its ability to _ us, reduce our sense of social exclusion and even reduce life's painful moments. "I was surprised" says Katherine Vohs, one of the researchers and professor at the University of Minnesota's Carlson School of Management. "The findings were surprising because no one had connected the meaning of money to pain. The money wasn't buying the subjects more friends; it was only psychologically helpful." In the research ,students were told they would be participating in a test of finger dexterity . One group was given some paper money to count, while the other group was given blank pieces of paper. Once the counting was complete, all the test subjects were asked to dip their fingers into bowls of water heated to 122 degrees--roughly the temperature of a very hot bath. Result? Those who had been counting money reported less pain than those who had not. Subjects also were asked about their feelings. Those who handled actual money reported feeling stronger even 10 minutes after they put down the cash. Combined with previous experiments, the findings confirmed what researchers have long doubted, that money acts as a general panacea in the brain, giving us social self-confidence and reducing physical pain without having to spend a dime on aspirin. But can we get the same effect by using credit cards? "No, credit cards do not have the same effect, " Vohs says. "They are scary for most people, and they in fact represent debt m many ways." The findings could have an interesting effect in the business world, where recent trends have been to issue non-monetary rewards and bonuses instead of what was thought of as "cold, hard cash". Question: What's Katherine Vohs's attitude towards the result of the study? Options: A: He found it totally unexpected. B: He had no doubt about it. C: He thought it needed further experiments. D: He thought it was not convincing.

I'm taking a test and have to guess the right answer to the question after the article. Article: One day, a brave jackal came to the river to drink some water. He saw a lion looking weak and tired, and asked, "What is the matter, King of the Jungle?" The lion told the jackal his story. The jackal felt sorry for the lion. He pulled and pulled at the lion's tail until the lion became free. The lion was very happy and said, "Thank you so much for helping me. I thought I would die! You are my friend for life! I would like you to come and live with me. From now on, I will hunt and share my food with you." The jackal moved in with the lion's family and had a wonderful time. Soon, the lion had children of his own and so did the jackal. The lioness was not happy about the friendship. She complained to her children. Her children complained to the jackal's children; the jackal's children complained to their mother and their mother complained to the jackal. The jackal was upset and told the lion, "You told me to live with you. If you don't like it any more, you should have said so yourself." The lion was shocked and said, "This is not true. I've never complained about you. I still want you to continue staying with me." The jackal said, "We understand each other. But our families don't. Perhaps it is better for us to live apart, but continue meeting each other when we are free. We can even hunt together!" The two families parted, but the lion and the jackal met often and remained friends for the rest of their lives. From the above paragraphs, we can conclude that in order to keep our good friendship, we have to give something up or give in in some particular cases. However, we can never give up or destroy our families. What do you think of it? Question: We can learn from the text that _ . Options: A: we should try to value true friends without giving up our family B: family relationship is more important than friendship C: it is easy to give up a friendship D: we should not make friends with those who refuse to help you
