Read the article and select the best answer. Article: Organic food, once considered something that only health fanatics desired, is now a regular feature at most supermarkets. And that has created a bit of a dilemma. On the one hand, you have a conventionally grown apple. On the other, you have one that's organic. Both apples are firm, shiny and red. Both provide vitamins and fiber, and both are free of fat, sodium and cholesterol. Conventionally grown food generally costs less, but is organic food a better choice? The advantages claimed for such foods over conventionally grown and sold food products are now being debated on a large scale. Supporters of organic foods -- a term whose meaning varies greatly --are frequently telling the world that such products are safer and more nutritious than others. The growing interest of consumers in the safety and nutritional quality of daily foods is a welcome development. However, much of this interest has been aroused by sweeping claims that the conventional food supply is unsafe or inadequate in meeting nutritional needs. Almost daily, the public is surrounded by claims for "no-aging" diets, new vitamins and other wonder foods. There are numerous unsubstantiated reports that natural vitamins are superior to man-made ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated grains are better than those treated with insect spray and the like. Although most of these claims are not supported by scientific evidence, large amounts of written material about the benefits of organic foods makes it difficult for people to separate fact from fiction. As a result, claims that eating a diet consisting of organically grown foods prevents or cures disease or provides other benefits to health have become widely advertised and form the basis for people's opinion. One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better... Question: It can be inferred from the passage that _ . Options: A: most doctors believe organic foods prevent disease or provide other benefits to health B: organic foods are actually less nutritious than conventionally grown foods C: people cannot separate fact from fiction because of the TV advertisements D: organic foods cost more but are not necessarily better than conventionally grown foods

Read the article and select the best answer. Article: Bolivia has a population of three and a half million. About one tenth of the total population are white; one-fourth are mixed Indians and white; and more than half are full-blooded Indians. The government and the industries are under the control of the white people. The Indians today live in much the same way as their ancestors. Most of them are farmers. Many work in the mines, for mining is the most important industry on Bolivia's. Of all the mining products, tin is the most important, which makes up three-fourths of all Bolivia's exports. The eastern slopes of the Andes, since there are very few roads there, are fertile but not highly developed. The two primary means of transportation are river boats and porters. East of the hill region is the great plains where tropical plants are grown. A serious problem for Bolivia is the transport of food from the warm regions, where it is grown, to the mountainous regions, where most of the people live. Bolivia gained its independence from Spain about a hundred years ago. It has been slow in developing, but its rich resources promise a better future in it. Question: Bolivia has been slow in developing , but it has hope for a better future because of its _ . Options: A: mining products B: rich resources Ks5u C: independence from Spain D: two primary means of transportation

Q: Read the article and select the best answer. Article: Like most parents, I worry that my child isn't getting enough sleep. Now it turns out that doctors have been warning kids don't get enough sleep for over a century--long before iPads, and texting robbed children of peaceful sleep. What's more, there's no solid scientific basis for pediatricians' recommendations on the amount of time children need to sleep. That's the word from researchers in Australia. It turns out that children are sleeping less than those in days of old. The researchers, at the University of South Australia's Health and Use of Time Group, found that kids' nightly sleep time declined by about three-quarters of a minute each year for the period they studied. My daughter was more likely to beg for a few more minutes of Angry Birds before bedtime.That means nowadays my daughter is sleeping about 50 minutes a night less than her grandfather who had to get up to milk the cows at 5:30 am. What hasn't changed is the predictions from health professionals on the consequences of lack of sleep. "This is a sleepless age and more and more... we are turning night into day," one expert said in 1905. Back then, sleep was seen as a way to restore "wearied brain tissue". Children and "clever" children were thought to be most at risk, and most in need of energy-restoring sleep. The words may be different today, but the threats are pretty much the same. Parents are told that children risk mental and physical problems, and even obesity, if they don't get enough sleep. So the Australians looked to see how much sleep kids do need. The answer is the biggest surprise of this study--no one really knows. "There is almost no exact evidence for proper sleep for children," the authors write. Their work was published in the journal Pediatrics. Question: If children suffer from lack of sleep for long . Options: A: they will become problem children B: they will take no interest in their studies C: they will be not fit for the present society D: they will be poor in mental and physical health
A: D

(Question)
Read the article and select the best answer. Article: Forks trace their origins back to the ancient Greeks. Forks at that time were fairly large with two tines that aided in the cutting of meat in the kitchen. The tines prevented meat from twisting or moving during cutting and allowed food to slide off more easily than it would with a knife. By the 7th century A.D., royal courts of the Middle East began to use forks at the table for dining. From the 10th through the 13th centuries, forks were fairly common among the wealthy in Byzantium. In the 11th century, a Byzantine wife brought forks to Italy; however, they were not widely adopted there until the 16th century. Then in 1533, forks were brought from Italy to France. The French were also slow to accept forks, for using them was thought to be awkward. In 1608, forks were brought to England by Thomas Coryate, who saw them during his travels in Italy. The English first ridiculed forks as being unnecessary. "Why should a person need a fork when God had given him hands?" they asked. Slowly, however, forks came to be adopted by the wealthy as a symbol of their social status. They were prized possessions made of expensive materials intended to impress guests. By the mid 1600s, eating with forks was considered fashionable among the wealthy British. Early table forks were modeled after kitchen forks, but small pieces of food often fell through the two tines or slipped off easily. In late 17th century France, larger forks with four curved tines were developed. The additional tines made diners less likely to drop food, and the curved tines served as a scoop so people did not have to constantly switch to a spoon while eating. By the early 19th century, four-tined forks had also been developed in Germany and England and slowly began to spread to America. Question: What is the passage mainly about? Options: A: The different designs of forks. B: The spread of fork-aided cooking. C: The history of using forks for dining. D: The development of fork-related table manners.
