Problem: Given the question: Write a multi-choice question for the following article: Article: The flag, the most common symbol of a nation in the modern world, is also one of the most ancient. With a clear symbolic meaning, the flag in the traditional form is still used today to mark buildings, ships and other vehicles related to a country. The national flag as we know it today is in no way a primitive artifact. It is, rather, the product of thousands of years' development. Historians believe that it had two major ancestors, of which the earlier served to show wind direction. Early human beings used very fragile houses and boats. Often strong winds would tear roofs from houses or cause high waves that endangered travelers. People's food supplies were similarly _ . Even after they had learned how to plant grains, they still needed help from nature to ensure good harvests. Therefore they feared and depended on the power of the wind, which could bring warmth from one direction and cold from another. Using a simple piece of cloth tied to the top of a post to tell the direction of the wind was more dependable than earlier methods, such as watching the rising of smoke from a fire. The connection of the flag with heavenly power was therefore reasonable. Early human societies began to fix long pieces of cloth to the tops of totems before carrying them into battle. They believed that the power of the wind would be added to the good wishes of the gods and ancestors represented by the totems themselves. These flags developed very slowly into modern flags. The first known flag of a nation or a ruler was unmarked. The king of China around 1000 B.C. was known to have a white flag carried ahead of him. This practice might have been learned from Egyptians even further in the past, but it was from China that it spread over trade routes through India, then across Arab lands, and finally to Europe, where it met up with the other ancestor of the national flag.

input question: Write a multi-choice question for the following article: Article: I've been living in China for a while -- long enough to observe the long-term deterioration of my own native language abilities, as well as those of my fellow English speakers. This deterioration can take different forms, one of which is the non-standard usage of the words. Its source is, specifically, Chinese culture, and its target is native English speakers. Below I give some of the common ways that the Chinese environment strikes down the native speaker's linguistic competence . Net bar: In Chinese, they're called "", This is fine. We generally call them "Internet cafe" in English. The Chinese seem to think that "" should be translated as "net bar" in English, and many careless foreigners have even been misled by this idea. Name card: In the English-speaking world, business people have lots of business meetings to discuss business. On these occasions, business people exchange specially printed pieces of paper known as business cards. In China everyone calls them "name cards", because in Chinese they are called "" and "name card" is a more direct translation . Bean curd. It's called "tofu," OK! This English word comes from Chinese. I know all dictionaries sold in China will tell you "" is "bean curd" in English and that may represent the two characters nicely, but "bean curd" is more a definition than a comfortable translation. And yet some foreigners start saying "bean curd" rather than tofu. Deplorable ! I think you see the pattern. The normal native way of saying something is replaced by a more unnatural way of saying it using other English words. If you've been living in China for a while and find yourself using all of these, you might be on dangerous ground. You're going to start making a fool of yourself back home. Look out! Resist Chinglish attempts at destroying your own command of your mother tongue!???
