I'm taking a test and have to guess the right answer to the question after the article. Article: Most musicians agree that the best violins were first made in prefix = st1 /Italy. They were made inCremona,Italy, about 200 years ago. These violins sound better than any others. They even sound better than violins made today. Violin makers and scientists try to make instruments like the old Italian violins. But they aren't the same. Musicians still prefer the old ones. No one really knows why these old Italian violins are so special, but many people think they have an answer. Some people think it is the age of the violins. They say that today's violins will also sound wonderful someday. But there is a problem here. Not all old violins sound wonderful. Only those from Cremonaare special. So age cannot be the answer. There must be something different aboutCremonaor those Italian violin makers. Other people think the secret to those violins is the wood. The wood of the violin is very important. It must be from certain kinds of trees. It must not be too young or too old. Perhaps the violin makers of Cremons knew something special about wood for violins. But the kind of wood may not be so important. It may be more important to cut the wood in a special way. Wood for a violin must be cut very carefully. It has to be the right size and shape. The smallest difference will change the sound of the violin. Musicians sometimes think that this was the secret of the Italians. Maybe they understood more than we do about how to cut the wood. Size and shape may not be the answer either. Scientists measured these old violins very carefully. They can make new ones that are exactly the same size and shape. But the new violins still do not sound as good as the old one. Some scientists think the secret may be the varnish, which covers the wood of the violin and makes it look shiny. It also helps the sound of the instrument. No one knows what the Italian violin makers used in their varnish. So no one can make the same varnish today. There may never be other violins like the violins of Cremona. Their secret may be lost forever.... Question: Some people think that modern violins _ . Options: A: will sound better in the future B: will sound worse in the future C: sound wonderful naturally D: will never be as old as those from Cremona

I'm taking a test and have to guess the right answer to the question after the article. Article: There is no doubt that Apple is well aware of the increased competition in the market and could be in a hurry to put another device out there, said Ramon Llamas, senior research analyst at IDC Mobile Devices Technology and Trends. Given its history with product launches and business policy, though, Apple probably isn't going to rush an iPhone release simply to put it on shelves, he said. "If you're Tim Cook (CEO of Apple), you're thinking if you want to pay more attention to how to keep growing that bottom line and keep investors happy, or continue with the same approach from Apple, which is do what we can do and manage products and releases in the best way they can work for us. Apple usually does things in their own time ,and I'm having a hard time buying this May or June timeline." Llamas told Mac News World. While it,s probable that Apple is definitely in a testing stage for its next smartphone , consumers likely have a standard wait for the finished product, said Colin Gibbs, analyst at GigaOm Pro. "It typically takes a year or longer to create a state-of-the-art smartphone, so no one should be surprised Apple is in the testing stages with the next iPhone. And while it's possible that Apple could launch the next iPhone this spring or summer, I'm not expecting to see it until a little later in the year," he told Mac News World. When it does launch, though, it could be in a variety of colors, said Gibbs. "Apple has already tested the waters with releasing colored devices when it revamped(,)its iPod line last fall, so it's not too much of a stretch to believe it would want the new twist with its smartphone, as well". "I wouldn't be surprised if the new iPhone becomes available in some new colors,'' he said. "That could be done pretty cheaply ,and it would give Apple a new marketing angle." Question: As for the next iPhone, Colin Gibbs didn't mention _ Options: A: the stage of its being tested B: the rough time of its being released C: the wide variety of its color D: the function to be improved

I'm taking a test and have to guess the right answer to the question after the article. Article: Why are people interested in eating raw foods or whole foods ? One reason is that eating these types of food reduces the risk of acid accumulation in your body. Raw and whole foods are usually digested more efficiently than cooked foods. When we cook foods, we destroy the natural enzymes that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is overweight. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive system, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs. Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we've had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body's cells. The body's metabolism becomes inactive, and the result is weight gain and obesity. The accumulation of acid in the digestive system makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common. To stop this vicious circle in its tracks, people need to consume food and supplements that will neutralize the acid already accumulated in body. Eating the right types of raw and whole foods can help. It's also important to restore your enzyme balance. You need to identify and avoid the foods that cause... Question: What is the main purpose of this passage? Options: A: To warn people of the problem of overweight. B: To inform people of the harm of processed foods. C: To advocate eating more raw and whole foods. D: To tell the differences between raw and processed foods.
