Ques:Article: Most people today think of chocolate as something sweet to eat or drink and can be easily found in stores around the world. It might surprise you that chocolate was once highly treasured. The wealthy people of Spain first enjoyed a sweetened chocolate drink. Later, the popularity of the drink spread throughout Europe. Chocolate remained a drink that only wealthy people could afford to drink until the eighteenth century. During the period known as the Industrial Revolution, new technologies helped make chocolate less costly to produce. Farmers grow cacao trees in many countries in Africa, Central and South America, but these trees are difficult to grow. They require an exact amount of water, warmth, soil and protection. After about five years, cacao trees start producing large fruits called pods, which grow near the trunk of the tree. The seeds inside these pods are harvested to make chocolate. Growing cacao is very hard work for farmers. Today, chocolate industry officials, activists, and scientists are working with farmers. They are trying to make sure that cacao can be grown in a way that is easy for the farmers and safe for the environment. The market value of the yearly cacao crop around the world is more than five billion dollars. Chocolate is especially popular in Europe and the United States. Each year, Americans eat an average of more than 5 kilograms of chocolate per person. Specialty shops that sell costly chocolate are also very popular. Many offer chocolate lovers the chance to taste chocolate grown in different areas of the world. Question: What made it possible to produce chocolate inexpensively? Yes or no, is the answer "New technologies."?

Ans:Yes

Ques:Article: Goats are being hired to do the work of men in a neighborhood just outside of San Diego. The fires that occurred in Hillborough four years ago destroyed thirty homes, most of which have been rebuilt. While the home were rebuilt, the grasses, bushes, and shrubs were re-growing. The area is now so overgrown in brush that it again brings a major danger of fire. The city government asked for bids to remove the brush. The lowest bid they received was $50,000. And that was if the city provided breakfast and lunch for the work crews for the six weeks it would take to clear the overgrown area. The city government said no, offering unlimited coffee and a doughnut a day for each crew member. When that offer was rejected, the city asked for help on its website. A sheepherder in Montana and a goat-herder in San Bernardino read about the city's problem while surfing the web on their laptops. They both offered to do the job for $25,000. The government chose the goat-herder because he lived closer. When told that the city dump was overflowing, the goat-herder said, "No problem. My goats will eat everything in your dump. Except for the automobile engines, of course." So, for another $5,000, the city killed two birds with one stone. If all goes well, they will invite the goat-herder and his "family" back every three years. The goat-herder said he will probably visit San Diego while his goats are in the dump. "I want to go there by plane; I just hope we don't crash. My goats would miss me a lot," he said. Question: What are the "two birds" that the city government kills with only one stone? Yes or no, is the answer "The danger of fire in a neighborhood and the overflowing dump."?

Ans:No

Ques:Article: When a person travels over long distances, the place may not be the only change. When his or her body rhythms get thrown off, he or she suffers from jet lag -- it's hard to sleep and eat at the right times in the new location. Humans and animals have a biological clock in their body that tells them when to sleep, and when to wake. When someone comes to a different place far away, this biological clock takes a while to match the day and night time of the new place. In a new study, reported in November's Science News, researchers at the University of California, Berkeley tested the effects of jet lag on hamsters . They wanted to know how serious jet lag would affect the brain and thinking habits of the animals. They think what happens to hamsters may happen to humans, too. In their experiments, the researchers first moved the hamsters' schedules forward by six hours. The animals' eating schedules, for example, were changed. If a hamster was often fed at noon and 4 pm, then it ate at 6 pm and 10 pm on the new schedule. People who travel from China to Europe experience the same shift, since the two regions are about six hours apart, half the shift between China and the USA. After three days, the scientists did it again - they shifted the hamsters' schedules forward by another six hours. Three days after that, they did it again; and then again three days later. For a full month, the scientists changed the hamsters' routines every three days. During the study, the hamsters slept the same amount every day as they did before the study. However, their sleep patterns had a hard time keeping up with the changing schedule. What's more, they seemed to feel low. The researchers also found that the hamsters had trouble with basic learning exercises during the study. The animals' thinking problems didn't go away when the experiment was over. A month after they went back living on a normal schedule, the hamsters still had trouble with basic mental tasks, such as learning and memory. The scientists concluded that serious... Question: We learn from the text that jet lag happens when someone _ . Yes or no, is the answer "flies to a distant place"?

Ques:Article: In Britain, it's bottoms up from the week before Christmas till the last firework explodes in the sky announcing the new year. The last Friday before Christmas, popularly known as 'Mad Friday', is one of the busiest periods for the country's pubs and clubs. But it's not just the bars that get busy. Ambulances and A&E departments around Britain get packed out too. Head injuries, cuts, falls...it's easy to end up hurting yourself or others when self-control disappear and your head is spinning due to alcoho1 revelers have been warned by the health authorities about the dangers of deadly drinking but drinking crazily seems to be part of the festivities for some. The charity Alcohol Concern is running a campaign of restriction by encouraging people to have a dry January. Jackie Ballard, the charity's Chief Executive, believes the campaign has been successful in recent years. She says, "More than two-thirds of people even six months later are drinking at reduced levels having had a month off drink. But also a study has shown the impact it has on people's health reducing their blood pressure and blood sugar levels." The study by the University of Sussex followed up nearly 900 participants in Alcohol Concern's Dry January campaign and found out that 72%of them had kept harmful drinking sessions down and 4%were still not drinking. Moderation seems to be the key to everything. The official recommendation for women is not to regularly drink more than 2 to 3 units of alcohol a day. The limit for men is 3 to 4 units of alcohol -- no more than a pint of 5.2%ABV lager, beer or cider. Question: The result of dry January campaign is that _ . Yes or no, is the answer "people can improve their health"?
