Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Have you wondered why different animals or pests have their particular colors? Colors in them seem to be used mainly to protect themselves. Birds, especially seagulls are very fond of locusts, but birds can't easily catch locusts because locusts change their colors together with the change of the color of crops. When crops are green, locusts look green. But when crops are ripe, locusts take on exactly the same brown color as crops have. Some other pests with different colors from plants are usually easily found and eaten by their enemies. So they have to hide themselves in terror for lives and appear only at night. If you study the animal life in any part of the world, you will find the main use of coloring is to protect themselves, bears, wolves and other beasts move quietly through forests. They are usually _ to the eyes of hunters, because they have the color much like the barks of trees. An even more strange act remains to be noticed. A kind of fish living in seas can send out a kind of very black liquid when it faces danger. While the liquid is over, its enemies cannot find it, and it quickly swims away. Thus, it has existed up to now though it is not powerful at all. Question: This passage mainly talks about _ . Options: A: the change of color in locusts B: the protective coloration of animals and pests C: how a certain sea fish protects itself D: animals or pests can dye themselves different colors

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: I know it is wrong to envy your children. But when I see my son, Tonio and his younger brother Sam going down a slide together, one's arm around the other, I know I have missed something wonderful. Not only did I never have a brother, but also I had no friendships like theirs. My sister was old enough to help take care of me, so she was more a mother than a playmate, and I was more a _ than a friend. A brother would have been wonderful, but it was not in the family planning. Now I finally live with brothers, my sons, Tonio and Sam. I am watching them build the kind of relationship that I once dreamed about. They go to bed together. When one comes into our bed after a nightmare, my wife and I know that before morning his brother will follow. Sam manages the world with more ease than his elder brother, whose frustrations often bring him to tears. With a sincere "Smile, Tonio," Sam is the one who comforts him. Tonio, on the other hand, has stopped playing with boys at his age who don't like playing with Sam. They are always backing each other up. I don't know what kind of relationship they will have when they grow up. Parents always want their children to have what they never could. I want them to have each other. So I imagine them going to the same college, marrying sisters and living on the same block. That's why I was so worried the day Tonio started kindergarten. I felt that I would lose something too. As we headed for school that morning, both boys seemed relaxed, as if neither had any idea that the day was going to be different, that starting then, Tonio would be leaving behind his brother, his best friend, his right arm. Tonio's first day was chaotic, with hundreds of children outside looking for their teachers. Before any of us could say goodbye, Tonio disappeared with his new classmates. He turned to wave and then was gone. It was so sudden. Sam even didn' t see him go. Although parents had been asked to ease the craziness of the first day by statying out of the school, I lifted Sam up and took him to... Question: On the first day of the kindergarten, _ .

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: The United States is faced with serious traffic problems. Too many cars travel on the freeways to and from the city. This heavy traffic causes delays and lots of pollution from cars that are using their engines but not moving anywhere. Many cars going nowhere is called a "traffic jam." While many cities in the United States have traffic problems, some of the worst are in Los Angeles, California. Los Angeles is a big city with a large downtown area. One of the reasons why there is so much traffic is that few people use public transportation to get around Experts say one possible solution to the traffic problem in Los Angeles would be to make people want to use the public transportation system of buses instead of their own cars. People say the buses should be made easier, faster, less costly and more dependable than driving a car. One suggestion is to reduce the cost of riding the bus. People who usually drive their cars could save a lot of money on gas and parking costs. Also, Los Angeles could make the buses easier for people to use. The buses could travel to more places in the city. And there could be more special lanes on the freeways that only buses could drive in. These changes would make taking the bus faster and easier than driving a car. Other experts have said that the best way to ease traffic problems is to charge people money to drive on the freeways. These charges, or tolls, would be for the most crowded roads. The tolls would be in effect during the times of day when most people drive to work and home again. These times in the morning and late afternoon are called "rush hour". People would try to avoid driving on these roads, which would decrease the amount of traffic. Also ,the money collected from these tolls could be used to improve the roads and public transportation system. Question: According to the passage, if the solutions were carried out, _ Options: A: more cars would be reduced and more roads would be built B: it would be easier but slower to take buses than to drive cars C: many people would prefer to walk around rather than drive cars D: the roads and public transportation system would be greatly improved
Answer:
D
