I'm taking a test and have to guess the right answer to the question after the article. Article: 3D printers are certainly the superstar today---they are being put to all kinds of uses, including creating model cars for movies. However, none of these ideas are as crazy as the one suggested by Anjan Contractor, who believes that they will be the key to ending world hunger . If you think that sounds a little crazy, you are not the only one, but after hearing scientists, the idea seems to become true. According to scientists, food will become _ expensive and possibly, even out of reach, for billions of people in the future. It means billions of people won't have enough food. This is where 3D printers may save the day. Anjan, an engineer says that the only way to support the large population will be to provide every kitchen with a 3D printer and print out meals. More importantly, it would be to make the basic food from things that we now do not think can be eaten. Anjan thinks that we could easily get the meat protein from insects . Similarly, the vegetable nutrition could be made from greens like grass. Would you want to try 3D printed food? Question: Anjan thinks that we can get the meat protein from _ in the future. Options: A: grass B: insects C: animals D: plants

I'm taking a test and have to guess the right answer to the question after the article. Article: There is one word you must learn before you visit the USA. That is "Freeze". Remember it has a special meaning besides the usual one. It means "stand still and don't move". Often policemen use it when they are ready to use their guns. If one doesn't obey the order and moves, he or she will be shot to death. One evening in Los Angeles, someone rang the bell of a house. It was a dangerous area at night, so the _ of the house took his gun with him when he answered the door. He opened the door and saw a strange man. But the man turned round and started walking away from the house. The owner cried: "Freeze", but the young man went on walking without obeying the owner's order. The owner thought he was trying to run away, so he shot at the young man and he was killed. Later, police found that the dead man was a Japanese student who was studying in Los Angeles University. He went to visit a friend, but unluckily could not remember the number of the house. When he realized he went to the wrong house he turned round and left. He didn't know much English and so didn't understand the word "Freeze". What a lesson we should get for this! Question: Which of the following is right? Options: A: When you hear the police or someone say "Freeze" in the USA, you must stop moving. B: Don't ring the bell of anyone's house in the USA at night. C: At last, the police found the dead man was a thief. D: The owner of the house was put into prison.

I'm taking a test and have to guess the right answer to the question after the article.

One day, one of his workmates was on business with him.The train car was so crowed that they couldn't even find a place to stand on. "Let's find seats to sit on," said the man. "Find seats? Just a joke?" said his workmate."Just follow me," said the man. They pushed their way through the crowds.The workmate wanted to give up , but the man insisted . At last,in the 7thcar they found two empty seats .They sat there happily at once. The workmate asked,"How do you know there are seats here?"The man answered ,"I didn't know it at all.But I know most of the passengers are easily cheated by one or two cars of crowed phenomena . Even though they know there are seats, they don't want to crowd among the groups.They think it's not worth doing that." The method seemed not to be clever enough,but it works. For us, patience will let us have a "seat ticket"life forever. ,. Question: Where did they find two empty seats? Options: A: In the 2th car B: In the 4th car C: In the 6th car D: In the 7th car
