Question: Read the following article and select the best answer. Article: Watching television makes it easier for toddlers to kick and scream, according to a U.S. study. Children under two should not watch any TV. The longer they sit in front of the box, the worse their behavior becomes. Just having the TV on in the background, even if the child wasn't watching it, was also connected to troublemaking behavior although the relationship wasn't as strong, said the researchers. "Parents should be smart about TV use," researcher Jennifer Manganello from the University at Albany, New York, said. "They should limit the time that children use TV, pay attention to the content of TV programs, and consider how TV is used throughout the home." The study looked at 3,128 women from 20 U.S. cities who had a child between 2005 and 2008. While there was some diversity of education among the women, one-third hadn't graduated from high school. Two-thirds of the mothers said their three-year-old watched more than two hours of TV a day, and the average viewing time for children was around three hours. On average, the TV was on for about five additional hours on a common day. After accounting for factors such as living in a violent neighborhood, scientists also found watching TV was strongly connected to behavior such as hitting others, having angry moods, being disobedient , and screaming a lot. The researchers thought that children may see violence on TV, and spend less time on positive development tasks such as reading or playing. The American Academy of Paediatrics suggests no TV at all for children at two and younger, and two hours a day or less for older kids. Question: what is the main idea of the passage? - Children should choose positive programs. - Children should keep away from TV. - Watching TV can make children violent. - Parents should watch less TV.
Answer: Watching TV can make children violent.

Question: Read the following article and select the best answer. Article: Millions of years ago dinosaurs lived on the earth. In the days of dinosaurs the whole earth was warm and wet. There were green forests and they could find enough to eat. Later, parts of the earth became cold and dry. and the forests there died. Then dinosaurs could not find enough to cat. This must be one reason why dinosaurs died out. We can guess another reason. New kinds of animals came on the earth. Some had big brains and were fast and strong. They could kill dinosaurs. There may be other reasons that we don't know about yet. Scientists are trying to make more discoveries about dinosaurs. Dinosaurs were of many sizes and shapes . Some were as small as chickens, while some were about 90 feet long. There were also terrible fights between dinosaurs. They might have happened more than 100 million years ago. Though there was no man to see any of the fights, we can be told by the animal's footprints that fight did take place. Question: According to the passage, dinosaurs did exist only _ on the earth. - for millions of years - millions of years ago - more than 100 millions years ago - when it was warm and wet somewhere
Answer: millions of years ago

Question: Read the following article and select the best answer. Article: A volcanic eruption in Iceland has sent ash across northern Europe. Airlines have stopped or changed the flights across the Atlantic Ocean, leaving hundreds of passengers stuck in airports. Grimsvotn is one of the largest and most active volcanoes in Europe. What makes Grimsvotn different is that it lies under a huge glacier of ice up to 12 metres thick. The hot volcano heats up the ice above it, which then forms a layer of water between glacier and the volcano, keeping it stable. As the water flows out from under the glacier, the pressure lifts. The lava from the volcano then comes up to the surface. This is exactly what is happening today. Now airlines have to make changes to their flights so as not to fly through the clouds of volcanic ash. According to KLM, one of Europe's biggest airlines, airplanes cannot go under the cloud or over it. Going through the cloud can result in ash getting stuck in the airplane's engines, causing damage to the plane. The eruption has also caused problems for animals in Iceland. The volcano left ash and sharp, glass-like rocks all over the countryside. Farmers are keeping their animals inside to stop them eating ash-covered grass or the sharp objects. Question: What keeps Grimsvotn still? - The slow flow of water.. - The thick glacier. - The water pressure. - The low water temperature.
Answer:
The water pressure.
