Input: Consider Input: Article: America, has always had people of many different nationalities and languages. The 1990 census indicates that almost 14% of Americans speak a non-English language at home. Yet only 3% reported that they spoke English "not well" or "not at all ". That means that slightly more than one out of 10 Americans could be considered _ . Besides that, many high school and college students---and even some elementary school students---are required to take a foreign language. Actually, a growing number of Americans are coming to appreciate the benefits of using different languages. Ethnic enclaves have preserved the language and culture of American immigrants. Some local residents can function quite well in their native language, without having to bother learning English. Regions such as southern Florida and the Southwest have numerous Spanish-speaking neighborhoods. In fact, Spanish speakers---numbering over 17 million---form the largest non-English linguistic group in America. But Chinese, Vietnamese, Italian, Polish and many other ethnic group add to the linguistic flavor of America. Foreign languages are so commonly used in some ethnic neighborhoods that visitors might think they are in another country! Although some Americans welcome this linguistic and cultural diversity, others have begun to fear that the English language is being threatened. Since the 1980s, the "English Only " movement has sought to promote legislation which would establish English as the "official language" and restrict the use of non-English language. However, some groups, including TESOL, the organization for Teachers of English to Speakers of Other language, object to such "language restrictionism". But so far, 19 states have passed "English Only" legislation, and the topic is the focus of an ongoing debate. Whether or not English is the official language of the United States, it remains the "language of wider communication". Nearly everyone recognizes the need to develop the ability in using English in order to do well in America. American also recognize that English is the international language, and people with good English skills can get by in many international settings. On the other hand, in a world growing increasingly smaller, second language skills can be a great favor. They can build cross-cultural bridges and give people an edge in a variety of career field. Indeed, lack of foreign language skill can limit one's chances for advancement and keep one in a cultural dead-end street.

Input: Consider Input: Article: Generations of Americans have been brought up to believe that a good breakfast is essential to one's life. Eating breakfast at the start of the day, we have been told, and told again, is as necessary as putting gasoline in the family car before starting a trip. But for many people, the thought of food as the first thing in the morning is never a pleasure. So in spite of all the efforts, they still take no breakfast. Between 1977 and 1983, the latest year for which figures could be obtained, the number of people who didn't have breakfast increased by 33%--from 8.8 million to 11.7 million--according to the Chicago-based Market Research Corporation of America. For those who dislike eating breakfast, however, there is some good news. Several studies in the last few years have shown that, for grown-ups especially, there may be nothing wrong with omitting breakfast. "Going without breakfast does not affect work," said Arnold E. Bender, former professor of nutrition at Queen Elizabeth College in London, "nor does giving people breakfast improve work." Scientific evidence linking breakfast to better health or better work is surprisingly inadequate, and most of the recent work involves children, not grown-ups. "The literature," says one researcher, Dr Earnest Polite at the University of Texas, "is poor."
Answer: breakfast is not as important as we thought before

Output: The main idea of the passage is that _ .

In China, businesses often open on August 8, and many couples register to get married at eight past eight on August 8. Superstitions about numbers are so widespread that some people--called numerologist--make a living by giving advice about numbers. In 1937, when the Toyoda family of Japan wanted to form a car company, they asked a numerologist if "Toyoda" would be a good name for the company. The numerologist said it would not be. He explained that "Toyota" would be a better name for the company. The family took his advice. As a result, millions of people drive "Toyota" and not "Toyoda" . There are many other kinds of superstitions. There are superstitions about eating, sleeping, sneezing and itching . There are superstitions about animals and holidays and horseshoes. There are even superstitions about superstitions. Those superstitions will tell people how to reverse bad luck. When the Japanese bump heads, they immediately bump heads again. According to a Japanese superstition, the first-bump means their parents will die, but the second bump "erases" the first bump To reverse bad luck in general, people turn around three times, turn their pockets inside out, or put their hats on backwards.
