I'm taking a test and have to guess the right answer to the question after the article. Article: Eating different colored foods can keep you healthy, as well as change your mood and behavior. Here is a list of colors, which can change your life. Blue/Purple Blue is considered to be peaceful and calming and it has the same effect on our health. The blue / purple color in food is due primarily to their anthocyanins which are antioxidants that are particularly heart healthy and may help support healthy blood pressure. Out of all the blue and purple foods available, blueberries are considered to have the highest antioxidant level. An analysis of the latest data from the National Health and Nutrition Examination Study found that people who eat purple and blue fruits and vegetables are at a reduced risk for high blood pressure and are less likely to be overweight. A food and health expert says that blue and purple color foods can prevent blood mass formation, and they also lower the risk of cancer. Foods that contain blue and purple colors are: reddish eggplant (especially the skin), blueberries, blackberries, purple grapes, etc. Green We all know that we should eat green as green symbolizes nature. The green foods are rich in isothiocyanates, which help resist cancer. Dr. Ashok Agarwal, a food and nutrition specialist, explains, "They are excellent sources of folic acid, vitamin K, as well as carotene . Diets high in those above are associated with lowered blood pressure." Foods that contain the green color are: broccoli, cabbage, cucumbers, etc. Red Lycopene in reddish fruits and vegetables is a powerful antioxidant that has been associated with a reduced risk of some cancers, and also provides protection against heart attacks. Dr. Smiths says, "Cooked tomato sauces are associated with greater health benefits as compared with the uncooked version as the heating process allows lycopene to be more easily absorbed by the body. Obtaining the most benefit from food depends on proper selection, storage and cooking of the produce." Foods that contain red color are: Tomatoes and tomato products, watermelon,...

I'm taking a test and have to guess the right answer to the question after the article. Article: Water runs downhill from mountaintops to streams to rivers to oceans. But downhill isn't the only way that water moves .A new study measures how water travels from country to country for human consumption. This flow isn't the type we usually think about .These scientists looked at the water used to grow and make the products which get shipped from nation to nation as imports or exports. They call this a flow of"virtual water ". We typically think about water as the liquid that flows from a tap. However,92%of the water used by people goes into growing crops,according to water researcher Arjen Hoekstra. He recently studied the hidden travels of virtual water used in products made from things like crops and meats .These products are shipped around the world. For example.consider a sugary soft drink. Hoekstra estimated that to produce one half-liter of the drink requires between 170 and 310litersofthewater--about 95%--is used to grow and process the ingredients .Another 4%goes into the packaging and labeling. In Hoekstra's calculation, when one country produces a half-liter of soda and sells it abroad,it exports as much virtual water as would fill a large refrigerator. According to Hoekstra's new report,dry countries like Israel and Kuwait,both in the Middle East, get the majority of their virtual water from other countries,through imported products. More surprisingly, some wetter countries,like the Netherlands and the United Kingdom, also get the majority of their virtual water from other places. That means that most of the water used to grow or produce the products and food consumed in those countries came from other countries. In the United States most of the virtual water used comes from American sources .In China even less of the water associated with its products Question: The passage is most probably a _ . Options: A: science news report B: book review C: newspaper advertisement D: science fiction story

I'm taking a test and have to guess the right answer to the question after the article. Article: I revisited Beichuan of Mid-Autumn Festival. As the car drove into the ruined city, tears streamed down my cheeks. Giant rocks from the mountain destroyed the road and houses fell, breaking into bricks and pieces of cement . Beichuan Middle School, which was once filled with energy and laughter, now so unrecognizable ,so empery, so quiet, so still, was a death valley. I couldn't really imagine at that moment, how much pain they had suffered or how hopeless they felt as they waited to be rescued. Those unfortunate ones watched the devil of death march over them, taking them away. I can't really imagine how heartbroken their parents or beloved ones were. As I wandered in the ruins, I was lost in deep thoughts. The day before, we were sitting in the brightly lit classroom, heatedly arguing the importance of shapes, color1s and styles in architecture , comparing ancient time housing with the modern ones. Their similarities, their differences, their pros and cons... Now , facing the terrible scene, I realized how childlike we were and how easily we forget the most important element of architect is SAFETY, it is how housing is supposed to be: to _ us from burning sun and pouring rain, to provide us with a comfortable warm place to sleep and relax. Obviously, the style and shape do play important roles in architecture. But when a natural disaster such as this earthquake came upon us without warning, will beauty stay over anybody's life? From this trip, we can no doubt give the clear loud answer; NO!!! Words after such a great disaster could appear nothing but empty and pointless. So many people's lives were taken, so much damage was done and a whole city was wiped out. Beichuan has become a history. Nevertheless, I still keep on dreaming and still long for a better future: to make our homes prettier yet safer. Question: What is the best title of this passage? Options: A: Safety Stands out from Anything B: Scenes of Post-disaster C: Importance of Architecture D: Relations between Architecture and Earthquake
