Read the following article and select the best answer. Article: The pen is more powerful than the sword. There have been many writers who use their pens to write things that were wrong. Mrs. Harriet Beecher Stowe was one of them. She was born in the U. S. A. in 1811. One of her books not only made her famous but has been described as one that excited the world, and was helpful in causing a civil war and freeing the enslaved race. The civil war was the American Civil War of 1861, in which the Northern States fought the Southern States and finally won. This book that shook the world was called Uncle Tom's Cabin. There was a time when every English-speaking man, woman, and child had read this novel that did so much to stop slavery. Not many people read it today, but it is still very interesting, if only to show how a warm-hearted writer can arouse people's sympathies. The author herself had neither been to the Southern States nor seen a slave. The Southern Americans were very angry at the book, which they said did not at all represent the true state of affairs, but the Northern Americans were widely excited over it, and were so inspired by it that they were ready to go to war to set the slaves free. Question: Mrs. Harriet Beecher Stowe became famous for _ . - one of her books - she was a very heartedly person - she was a kind wife - she worked for the war
one of her books

Read the following article and select the best answer. Article: Every day, millions of shoppers hit the stores in full force--both online and on foot--searching for the perfect gift. Aside from purchasing holiday gifts, most people regularly buy presents for other occasions throughout the year, including weddings, birthdays, anniversaries, graduations, and baby showers. This frequent experience of gift-giving can cause _ feelings in gift-givers. Many enjoy the opportunity to buy presents because gift-giving offers a powerful means to build stronger bonds with one's closest persons. At the same time, many fear the thought of buying gifts; they worry that their purchases will disappoint rather than delight the intended receivers. What is surprising is that gift-givers have considerable experience acting as both gift-givers and gift-recipients, but nevertheless tend to overspend each time they set out to purchase a meaningful gift. In the present research, we propose a unique psychological explanation for this overspending problem -- i.e., that gift-givers equate how much they spend with how much receivers will appreciate the gift (the more expensive the gift, the stronger a gift-recipient's feelings of appreciation). Although a link between gift price and feelings of appreciation might seem intuitive to gift-givers, such an assumption may be unfounded. Indeed, we propose that gift-receivers will seldom tend to base their feelings of appreciation on the significance weight of a gift than givers assume. Why do gift-givers assume that gift price is closely linked to gift-recipients' feelings of appreciation? Perhaps givers believe that bigger (i.e., more expensive) gifts convey stronger signals of thoughtfulness and consideration. According to Camerer (1988) and others, gift-giving represents a symbolic ritual , by which gift-givers attempt to signal their positive attitudes toward the intended receiver and their willingness to invest resources in a future relationship. In this sense, gift-givers may be motivated to spend more money on a gift in order to send a "stronger... Question: The authors refer to work by Camerer and others in order to _ . - offer an explanation - introduce an argument - question an intension - support a conclusion

Ques: Read the following article and select the best answer. Article: The term "smog" was first used in London during the early 1900's to describe the combination of smoke and fog. What we typically call " smog" today is a mixture of pollutants but is primarily made up of ground-level ozone . Ozone can be beneficial or harmful depending on where it stays. The ozone staying high above the Earth protects human health and the environment, but ground-level ozone is responsible for the choking, coughing, and painful eyes associated with smog. The ozone in smog also prevents plants growth and can cause widespread damage to crops and forest. Major smog occurrences often are linked to heavy motor vehicle traffic, high temperatures, sunshine, and calm winds. Weather and geography affect the position and severity of smog. Because temperature regulates the length of time it takes for smog to form, smog can form faster and be more severe on a hot and sunny day. When warm air stays near the ground instead of rising and winds are calm, smog may stay trapped over your city for days. As traffic and other sources add more pollutants to the air, the smog gets worse. Smog is often more severe away from the pollution sources because the chemical reactions that cause smog occur in the atmosphere while the reacting chemicals are being moved by the wind. Smog is a visible example of air pollution. You can look into the distance during the day to see how much smog there is in the air. In addition, most cities measure the concentrations of pollutants in the air and report the results to the public. Environmental Protection Agency sets national standards for pollutants. Areas that fail to meet the standards for at least one air pollutant are called "nonattainment areas. " New measures are being taken by local governments across the country to reduce air pollution in nonattainment areas. These include: banning charcoal barbecues and wood burning in stoves or fireplaces when pollution levels are high; developing programs to encourage carpooling and voluntary "ozone actions" ;... Question: Which indication shows more exact the air is poor? - Heavy motor vehicle traffic in big cities. - Widespread damage of crops and forest. - Clear outlines of hills in the distance. - High concentrations of pollutants in the air.
Ans: High concentrations of pollutants in the air.

Ques: Read the following article and select the best answer. Article: Picky eaters may have good reasons for their behaviour. No matter why your child has become picky, how you handle the situation can affect his or her future. Therefore, you should know the following reasons for picky children first of all. _ is common in children; it often happens at the dinner table. Some children just refuse to try new food because they don't know what it will taste like, while others dislike new food before even smelling it. Some children take it to the extreme and will only eat a few foods that they like. Psychologist Dr. Elizabeth Capaldi says that, by the time children reach the age of two, they have formed their own eating habits that they don't want to be disturbed by new offerings at the table. A newly published study led by Dr. Lucy Cooke of University College London showed that picky eating in children results from genetic and environmental causes. The research, which followed the eating habits of 5,390 pairs of twins between the ages of 8 and 11, found that about 75% of the neophobia in the children was from their parents, while 25% was due to the influence of environment. Children grow at a high speed during their first year, but that fast-paced growth tends to slow down by their second year. When children are not experiencing one of those fast growth periods, their body needs less energy; and that results in a smaller appetite . When children are not hungry, they tend to enjoy only food they like. They refuse new food and food that is not their favourite. Some children will limit the amount of food to only one kind, like hamburgers or pancakes, leaving all the other foods untouched. In some cases, many real reasons why a child behaves as a picky eater exist. About 5% of children who are 10 years of age or younger have some type of neurological dysfunction that influences their eating habits. These children may be easily hurt by some special smells, or their brain may not be able to process such sensory information properly. Question: What can we learn about the study led by Dr. Cooke? - It paid more attention to the environmental effects on children's eating habits. - It followed the eating habits of 5,390 children aged between 8 and 11. - It showed that genetics greatly affect children's eating habits. - It suggested that parents should have good eating habits.
Ans:
It showed that genetics greatly affect children's eating habits.
