Read the following article and select the best answer. Article: A new study has found evidence of aggressive behavior in children who drink four or more servings of soft drinks every day. Information for the study came from the mothers of 3,000 5-year-olds. Researchers asked the women to keep a record of how many servings of soft drinks their children drank over a two-month period. They were also asked to complete a checklist of their children's behavior. The researchers have found that 43 percent of the children drink at least one daily serving of soda, and 4 percent of the youngsters have even four or more sodas to drink every day. Shakira Suglia, a famous expert, says they've found that children who drink the most soda are more than twice as likely as those who drink no soda to show signs of aggression. "For the children who consume four or more soft drinks per day, we see more _ behaviors, which make them hard to get along well with others." The aggressive behaviors include destroying possessions belonging to others, taking part in fights and physically attacking people. The researchers have determined the link after considering factors like the child's age and sex. They have also considered other possible influence, such as whether the boys and girls are eating sweets or giving fruit drinks on a normal day. In addition, the researchers have examined parenting styles and other social conditions that may be taking place in the home. Researches are trying to find why young children who drink a lot of soda have behavior problems. An ingredient often found in soft drinks is caffeine, which helps to make people feel energetic. Doctor Suglia suggests that caffeine could cause the 5-year-olds to be more aggressive. Earlier studies of adults have found the highest sugar levels in those who carry weapons and show signs of negative social behavior. Question: According to the research, which of the following is right? - Mothers were asked to keep a record of how many servings of soft drinks their children drank over a three-month period. - 4 percent of the youngsters have even four or fewer sodas to drink every day. - Children who drink no soda show fewer aggressive behaviors. - Children with the highest sugar levels tend to carry weapons and show signs of negative social behavior.
Children who drink no soda show fewer aggressive behaviors.

Read the following article and select the best answer. Article: It is now commonly known that AIDS is a deadly disease. It does great damage to human beings' immune system, weakening resistance to disease and leading to death due to utter weakness. To this day, there are no existing drugs that can kill AIDS virus. It is a deadly battle between science and AIDS. This is only one side of the story. Although it can not be cured, AIDS is preventable. For those who have not caught the disease, the knowledge of preventive measures seems to be the most powerful weapon at hand. Since the discovery of the first AIDS patient in 1985, the number of HIV carriers is on an alarming rise in China and statistics show that young people are the more likely victims of AIDS. Nationwide there are 214 million people between the ages of 13 and 22, most of whom are students. If no measures are taken to protect these young people, it is almost certain that the threat of AIDS will be very real to them. There has been a great deal of misinformation concerning the transmission of AIDS. One of the most misleading myths is that AIDS can be transmitted by casual physical contact such as kissing, shaking hands or sharing food container. Surveys and investigations conducted in some universities and colleges show that half of those people questioned are not clear about how AIDS is transmitted, not to mention how it is prevented. This is the driving force behind the State Education Department's decision to spread AIDS awareness information among college students and later to high school students and primary school students. Question: By writing "This is only one side of the story", the author suggests that _ . - although we can't cure AIDS, we can manage to prevent it. - AIDS is very dangerous, but we should not be scared of it. - AIDS is not curable, but doctors should not give up fighting against it. - although the doctors cannot cure the disease, they can help improve the patients' health.
although we can't cure AIDS, we can manage to prevent it.

Q: Read the following article and select the best answer. Article: Everyone has heard of the San Andreas fault , which constantly threatens California and the West Coast with earthquakes. But how many people know about the equally serious New Madrid fault in Missouri? Between December of 1811 and February of 1812, three major earthquakes occurred, all centered around the town of New Madrid, Missouri, on the Mississippi River. Property damage was severe. Buildings in the area were almost destroyed. Whole forests fell at once, and huge cracks opened in the ground, releasing some strong smell chemicals. The Mississippi River itself completely changed character, developing sudden rapids and whirlpools . Several times it changed its course, and once, according to some observers, it actually appeared to run backwards. Few people were killed in the New Marid earthquakes, probably simply because few people lived in the area in 1811; but the severity of the earthquakes are shown by the fact that the shock waves rang bells in church towers in Charleston, South Carolina, on the coast. Buildings shook in New York City, and clocks were stopped in Washington, D.C. Scientists now know that America's two major faults are essentially different. The San Andreas is a horizontal boundary between two major land masses that are slowly moving in opposite directions. California earthquakes result when the two masses make a sudden move. The New Madrid fault, on the other hand, is a vertical fault; at some points, possibly hundreds of millions of years ago, rock was pushed up toward the surface, probably by volcanoes under the surface. Suddenly, the volcanoes cooled and the rock collapsed, leaving huge cracks. Even now, the rock continues to settle downwards, and sudden sinking motions cause earthquakes in the region. The fault itself, a large crack in this layer of rock, with dozens of other cracks that split off from it, extends from northeast Arkansas through Missouri and into southern Illinois. Scientists who have studied the New Madrid fault say there have been numerous smaller quakes in the... Question: This passage implies that _ . . - horizontal faults are more dangerous than vertical faults - Vertical faults are more dangerous than horizontal faults - The volcanoes that caused the New Madrid fault are still alive - A lot of people would die if the 1811 New Madrid earthquakes happened today
A: A lot of people would die if the 1811 New Madrid earthquakes happened today
