I'm taking a test and have to guess the right answer to the question after the article. Article: Did you ever wonder how some of your favorite foods, products or toys came about? Believe it or not, they may have been an accident, or a failure of some other intention. Below, we found three mistakes we're thankful for turned out to be what they are. 1. Most historians hold that the Chinese invented fireworks in the 9th century when they discovered how to make gunpowder. Story has it that a Chinese cook accidentally mixed together what were then considered common kitchen items and noticed they burnt. When put tightly in a bamboo tube and lit, it blew up. 2. In May of 1886, a law led John Pemberton, a pharmacist , to rewrite the formula for "Pemberton's French Wine Coca," his popular headache treatment. Containing sugar instead of wine as a sweetener, the outcome became something for Coke, which was later mixed with carbonated water. His bookkeeper suggested the name Coca-Cola because he thought the two C's would look good together, which is how what we call Coca-Cola, a world -wide drink came into being. 3. During World War II, scientists at the University of Birmingham invented the magnetron--an important heat-producing part of the microwave oven . While working for Raytheon Corporation after the war, the American engineer Percy Spencer was testing the magnetron when a chocolate bar in his pocket melted. He went on to test other foods including popcorn kernels, and found it to be a much more efficient way to cook. In 1947 Raytheon came out with the first restaurant microwave oven, which was six feet tall and weighed 750 lbs. Question: What's the best title for the passage? Options: A: What great inventions they are! B: Inventions from Three Countries. C: Stories of Accidental Inventions. D: The Human Inventions of time.

Eight boys and 12 girls were killed - all but four of them were aged six. The youngest, Noah Pozner, celebrated his birthday only last month.

I'm taking a test and have to guess the right answer to the question after the article. Article: A family in Guelph, Ontario is spending a year living "in 1982". They're doing it so their kids can see what life was like before technology like iPads, computers and even coffee machines was part of everyday life. They have stopped using all technology from their home and are relying on the things people would have used back in the 80s. There is a box at the front door where people can put their cell phones in, while they're visiting the family. Blair McMillan and his wife Morgan want their kids--Trey, 5, and Denton, 2--to have a year without technology. Instead of reading e-readers, they are reading books. Instead of using a GPS, they used paper maps. The home the family is living in was built in the 1980s. Even the way they dress and style their hair is from the 80s. The whole idea started when young Trey was called to come outside. He didn't because he was busy playing on the ipad. That's why his dad thought of the idea of living "in 1982" for a year. The family plans to live like "it's 1982" until April next year. To them, one of the hardest things was giving up their cell phone. Question: Who made the family have the idea of living "in 1982"? Options: A: The reporter. B: Young Trey. C: Blair McMillan. D: Morgan.

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: We can conclude from the article that _ . Options: A: fat people are usually lazier than lean people B: people should switch between different types of diets to keep healthy C: being overweight and being lazy can feed into each other D: laziness is the main cause of weight problems
