Problem: Write a multi-choice question for the following article: Article: Supply and demand is perhaps one of the most basic concepts of economics and it is the backbone of a market economy. Demand refers to how much of a product or service is desired by buyers. The quantity demanded is the amount of a product people are willing to buy at a certain price; the relationship between price and quantity demanded is known as the demand relationship. Supply represents how much the market can offer. The quantity supplied refers to the amount of a certain goods producers are willing to supply when receiving a certain price. The relationship between price and how much of a goods or service is supplied to the market is known as the supply relationship. Price, therefore, is a reflection of supply and demand. The law of demand states that, if all other factors remain equal, the higher the price of a product, the fewer people will demand that product. The amount of goods that buyers purchase at a higher price is less as the price of a product goes up, so does the opportunity cost of buying that product. Like the law of demand, the law of supply shows the quantities that will be sold at a certain price. But unlike the law of demand, the supply relationship shows an upward slope. This means that the higher the price, the higher the quantity supplied. Producers supply more at a higher price because selling a higher quantity at a higher price increases the whole income. Now that we know the laws of supply and demand, let's turn to an example to show how supply and demand affect price. Imagine that a CD of your favorite band is sold for $20. Because the record company's previous analysis showed that consumers will not demand CDs at a price higher than $20, only ten CDs were sold because the opportunity cost is too high for suppliers to produce more. If, however, the ten CDs are demanded by 20 people, the price will then rise. As a result, the rise in price should cause more CDs to be supplied as the supply relationship shows that the higher the price, the higher the quantity supplied. If,...

input question: Write a multi-choice question for the following article: Article: Travelling and even living abroad can be great for broadening your horizons and learning about different cultures. However, after returning home from being abroad for a long period, many people can suffer from the problem of reverse culture shock. Reverse culture shock is a condition that happens when you return home and find things have changed greatly from how you have remembered them while you are away. It develops feelings of anxiety, hostility and boredom. One of the biggest change people encounter when returning home after spending a great deal of time abroad is that their relationships with friends and family are not as familiar as they once used to be. While reverse culture shock is a very common condition, there are actually many ways you can deal with and lessen the effects of this condition. Posting a regular blog, or updating your status on Facebook or Twitter, can really help to keep your friendships with people back at home. The best thing about posting regular updates is that your friends and family always know what you are getting up to, so they won't be surprised by the changes they see in you when you do finally return home. You could even ask close family and friends to keep you updated on life at home so you are not left feeling shocked by changes that might happen while you are away. If you are left feeling a bit upset that none of your friends want to hear all about your amazing travel stories when you get home, then why not try sharing the world with them by writing online travel reviews. For those who are considering travelling abroad, your experiences could prove very useful, and may even encourage them to do some of the things you are lucky enough to have experienced while you were away.???

[Q]: Write a multi-choice question for the following article: Article: United States and Canada are multicultural countries with many national, religious and cultural differences, where people attach great importance to individualism--the uniqueness among people. Teachers value the qualities that make each student special and different. You can see such values through their educational systems. For example, students needn't memorize lots of information. Instead, they work independently and find answers on their own. There are discussions for children to show their own ideas and opinions. By contrast, people have the same language, history, and culture in most Asian societies. As a result, Asia's educational system reflects society's belief in group goals and purposes rather than individualism. Children in China, Japan, and Korea learn to work together and help one another in assignments. And the teaching methods are often very formal and serious. In class, teachers give lectures while students listen and take notes. Discussion is replaced by reciting rules of information that have been memorized. These two systems both have advantages and disadvantages. One advantage in Japan is that there is much more math and science than American students learn by the end of high school. In addition, students study more hours each day and more days each year than North Americans do. The difficult system also prepares students for a society that place emphasis on discipline and self-control. However, while memorization is an important learning method in Japanese schools, yet many students admit forgetting much of the information that they have memorized after exams. On the other hand, the educational system in North American has an advantage that students learn to think for themselves, which prepares them for a society that values creativity. The disadvantage is that when they graduate from high school, they haven't recited as many basic rules and facts as students in other countries have.
