Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: The airline lost your baggage. The hotel laundry ruined your favorite shirt. The taxi driver asked for more money. When you're abroad, sometimes things go wrong. Now you can do something about it! Use these tips when you want to express an effective complaint in English. No matter how unfair the situation is, it's best to express your complaint politely. In English, you'll sound more polite if you use indirect language. Here are some examples: "I'm sorry to bother you..." Starting a complaint like this puts the listener who may have heard many complaints that day at ease. Use this phrase if the situation isn't that serious. For example, "I'm sorry to bother you, but I wanted a baked potato, not fried." "Can you help me with this?" Everyone would rather be asked to do something than told! So try expressing your complaint as a request for help: "Can you help me with this? My shirt came back from the laundry without buttons." "I'm afraid there may be a misunderstanding." This is a polite way of saying, "Your information is wrong. Please fix it now." You'll most likely use this phrase if you made reservations for a flight, hotel or restaurant, and when you arrive, it's not what you expected. For example, "I'm afraid there may be a misunderstanding. I requested a non-smoking room." "I understand it's not your fault..." Often when you make a complaint, you deal with a person who was not directly responsible for the problem. But the problem isn't your fault, either! This phrase is helpful when you need swift action. Tell the person you're dealing with that you understand they're not at fault and then directly state the problem: "I understand it's not your fault, but the airline promised they would deliver my baggage yesterday." "Excuse me, but I understood that..." Using this phrase lets the person know you're well-informed and doubt they might be trying to take advantage of you. Don't say, "Hey! You're trying to cheat me!" Instead, start indirectly by stating what you know to be true: "I understood that the taxi... Options: A To give an introduction of life abroad. B To offer advice on giving complaints in English.

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Do you always forget where you placed your keys or your purse? What was the name of the movie you saw last week? The major cause of your forgetfulness may be linked to what you store in your body, not in your short-term memory bank. Tests continue to show that people with enough Vitamin B-2 do well in memory exams. The "B" could stand for "brain", if you're one of many with limited instant recall. And the number one source of that vitamin is sunflower seeds. Even when you're sleeping or relaxing, your brain is still at work. Although it makes up just two percent of your total body weight, it uses up to 30 % of the calories you take in each day. For it to work properly, it must be fed. Even if you're not a breakfast eater, that meal is the best way to prepare your brain for the day. A quick and easy English _ with peanut and butter in it, a glass of milk, and an orange, might be what your brain may be asking you the first thing in the morning when you feel your head is in a fog. Having sunflower seeds and fruit between meals adds more muscle to that hungry, demanding organ. Vitamin B-1 also helps the memory, and that is found in eggs, meats and nuts. In Chinese culture, walnuts are known as the fruit for a long life because it is believed that they feed both the kidneys and the brain. And according to Chinese culture, if you keep those two important organs in good working order, you'll live longer. However forgetful you are, just keep in mind the letter "B", which will help you to "bear in mind almost everything" even on those days when life's challenges are sending you in a billion directions. Options: A Keep in mind the letter "B" B The younger, the better memory C Learn about Chinese culture D Try to get more rest Answer: A Keep in mind the letter "B" Question:

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: On the night of July 6, 1943, a plane took off from an Air Force base in England to stop German fighters over the English Channel. Piloting the plane was Captain Thomas Nash. Looking westward, Nash saw twelve orange lights in a row, moving at a very high rate of speed. Thinking they might be a new German weapon, he swung the plane around and headed directly for the lights, but they disappeared. Captain Nash may have been the first to see such orange lights but he wasn't the last. His experience was repeated many times by pilots during World War II both in England and Far East. What were they? No one knows for sure, but there is an interesting theory to explain them. According to this theory, the orange lights are space animals---animals specially adapted to life in the upper atmosphere just as some living things are adapted to life at the bottom of the sea. These space animals, the theory says, live so far up in the atmosphere that they are not in sight from the earth. They feed partly on the air and partly on energy from the sunlight. Being almost pure energy themselves, their body shine at night. During the day, however, they are invisible. Before World War II, continues the theory, there was little radiated energy on the earth's surface. Then came the development of rockets, nuclear power stations and something like that. The space animals are attracted to these kinds of energy of food. At night when there is no energy from the sunlight, they come down into the lower levels in search of a meal. They may even float into the range of human eyesight. This explains the fact that they have been sighted many times from the earth since 1943. Options: A shine brightly in the sky B cannot be seen C are in sight now and then D visit the earth's surface Answer: B cannot be seen Question:
