Article: One evening after dinner, Mr. and Mrs. Tisich called a family meeting. --We've had to make a difficult decision, Mr. Tisich announced. --You see, your mother has been offered a post as co-director of a television station in Chicago. Unfortunately, the station is not here. After thinking long and hard about it, we've concluded that the right decision is to move to Chicago. Marc looked shocked, while his sister Rachel breathlessly started asking when they'd be moving. --It's surprising, but exciting! she said. Marc simply said, --We can't go--I can't leave all my friends. I'd rather stay here and live with Tommy Lyons! The Tisichs hoped that by the time they moved in August, Marc would grow more used to the idea of leaving. However, he showed no signs of accepting the news, refusing to pack his belongings. When the morning of the move arrived, Marc was nowhere to be found. His parents called Tommy Lyon's house, but Mrs. Lyons said she hadn't seen Marc. Mrs. Tisich became increasingly concerned, while her husband felt angry with their son for behaving so irresponsibly. What they didn't know was that Marc had started walking over to Tommy's house, with a faint idea of hiding in Lyons's attic for a few days. But something happened on the way as Marc walked past all the familiar landscape of the neighborhood: the fence that he and his mother painted, the tree that he and his sister used to climb, and the park where he and his father often took evening walks together. How much would these mean without his family? Who make them special in the first place? Marc didn't take the time to answer that question but instead hurried back to his house, wondering if there were any moving cartons the right size to hold his record collection. Question: The reason for Marc's going home was that _ . Yes or no, is the answer "he realized his family was very important to him"?
No

Article: Coca-Cola is probably the most famous brand in the world, and in some areasyou can even access it easier than clean drinkable water. Although the company is trying to present itself as a health-conscious company, you can't really say that drinking cola is healthy for you. Still, we all drink cola, some more and some less, and we tell ourselves that it's all okay as long as we don't overdo it. However, Coca-Cola has other functions besides drinking. Cola removes the tarnish from old pennies. Got some old rusty pennies? Not to worry! Put them inside a glass of cola and let them rest for a while. When you get them out, you'll have shiny pennies that will look as if they were coined a couple of days ago. If you couldn't clean those pennies with industrial acids, just buy a can of cola and let it do its magic! You can remove gum from your hair with cola. If you've got gum stuck in your hair and don't know a better way to get it out, don't worry, you won't have to cut it. Just pour some cola into a bowl and dip the part of your hair with gum on it inside. Leave it for a couple of minutes and then simply wipe off the gum. You can make an exploding fountain. You probably know about this one. You can make an exploding fountain by putting a mint inside a two-liter bottle. Then move away from the bottle and get ready for a Coca-Cola explosion. This is a fun thing to do, but it is also a warning -- don't eat a mint and drink cola at the same time, because a similar thing could happen to your stomach. Question: What's the main idea of the text? Yes or no, is the answer "Some of the strangest uses of Coca-Cola."?

Article: Inland waters may be grouped into two general classes: standing waters and flowing waters. As is often the case, the boundary between these two classes is not sharp and clear. A pond is an example of standing water. But most ponds are fed by springs or brooks and most have an outlet. Thus some current of changing water flows through them. On the other hand, a river is an example of flowing water. In some places, however, a river may have such a slow current that it is very difficult to detect. Standing inland waters differ in size, in age, and in many _ environmental characteristics. They range in size from roadside puddles to the Caspian Sea. Puddles may last for only a few days or weeks; ponds, for a few hundred to a thousand years. In general, lakes are older, though the waters of some tropical "lakes" disappear completely during each dry season. Standing waters vary from very shallow to very deep, from clear to muddy, from fresh to salty. In flowing waters we roughly distinguish between brooks, creeks, and rivers. The size and age of flowing waters are unimportant. Speed of flow, clearness, oxygen content, and other chemical characteristics are used by scientists in studying flowing-water ecosystems. Question: This passage mainly tells us that _ . Yes or no, is the answer "there are two major classes of inland waters"?

Article: "Fire! Fire!" What terrible words to hear when one wakes up in a strange house in the middle of the night! It was a large, old, wooden house and my room was on the top floor. I jumped out of bed, opened the door and stepped outside the house. There was full of thick smoke. I began to run, but as I was still only half-awake, instead of going towards the stairs I went in the opposite direction. The smoke grew thicker and I could see fire all around. The floor became hot under my bare feet. I found an open door and ran into a room to get to the window. But before I could reach it, one of my feet caught in something soft and I fell down. The thing I had fallen over felt like a bundle of clothes, and I picked it up to protect my face from the smoke and heat. Just then the floor gave way under me and I crashed to the floor below with pieces of burning wood all around me. I saw a doorway in fire, then I put the bundle over my face and ran. My feet burned me terrible, but I got through. As I reached the cold air outside, my bundle of clothes gave a thin cry, I nearly dropped it in my surprise. Then I was in a crowd gathered in the street. A woman in a night-dress and a borrowed man's coat screamed as she saw me and came running madly. She was the Mayor's wife, and I had saved her baby. Question: When the fire arose in the middle of the night, the author was _ . Yes or no, is the answer "sleeping"?
No
