Read the following article and answer the question. Article: The English language was first introduced to the Americas by British colonization, beginning in 1607 in Jamestown, Virginia. Similarly, the language spread to numerous other parts of the world as a result of British trade and colonization elsewhere and the spread of the former British Empire, which, by 1921, held sway over a population of 470-570 million people, approximately a quarter of the world's population at that time. Over the past 400 years the form of the language used in the Americas--especially in the United States--and that used in the United Kingdom have diverged in a few minor ways, leading to the versions now occasionally referred to as American English and British English. Differences between the two include pronunciation, grammar, vocabulary, spelling, punctuation, idioms, and formatting of dates and numbers. A small number of words have completely different meanings in the two versions or are even unknown or not used in one of the versions. One particular contribution towards formalizing these differences came from Noah Webster, who wrote the first American dictionary (published 1828) with the intention of showing that people in the United States spoke a different dialect from Britain, much like a regional accent. It may be the case that increased worldwide communication through radio, television, the Internet and globalization has reduced the tendency towards regional variation. This can result either in some variations becoming extinct (for instance, the wireless, being progressively superseded by the radio) or in the acceptance of wide variations as "perfectly good English" everywhere. Chief among other native English dialects are Canadian English and Australian English, which rank third and fourth in the number of native speakers. For the most part, Canadian English, while featuring numerous British forms alongside native Canadianisms, shares vocabulary, phonology and syntax with American English, leading many to recognize North American English as an organic grouping of dialects.... Question: This passage is intended _ Answer:

OPTIONS:
- to persuade us to speak perfectly good English in the future.
- to draw people's attention to the extinction of different English dialects.
- to give the readers some useful information on variation of the English language.
- to do a research on how the English language has influenced the world.

Q: Read the following article and answer the question. Article: The fictional Chinese-American detective Charlie Chan was the subject of popular books and movies for many decades. In recent years, however, the character has been criticized as an ill image of Asian-Americans. Yunte Huang, an English professor at the University of California, says that's not the case. He has been exploring the character and real-life policeman who inspired him. Charlie Chan has been a familiar character to readers and film-goers, beginning in the 1920s. The detective solved crimes around the world in more than 40 films through the 1940s, and with the invention of television, found a new audience in the 1950s and 1960s. Huang discovered Charlie Chan through books by American author Earl Derr Biggers, who created the character. "One day, I happened to find two Charlie Chan novels. At that point I thought I knew that he was a negative character against Asians, but when I read the book," he says, "I was immediately attracted. Ever since then, I've been a fan of Charlie Chan." As a fan of the books and films, Huang was surprised to learn that Charlie Chan was based on a real detective named Chang Apana, who was born to Chinese parents in Hawaii around 1871. Apana worked as a cowboy, and joined the Honolulu police force in 1898. "He almost immediately became a local legend because as a former cowboy," says Huang, "he would walk the most dangerous areas in Chinatown carrying a bullwhip instead of a gun. He didn't need that." Although some say the image of Charlie Chan, with his broken English, is embarrassing for Asian-Americans, Huang believes Chan's broken English and unusual ancient sayings were part of his charm . "Let me just quote a few - 'Actions speak louder than French,' or 'Mind like parachute . Only function when open.' Charlie Chan always owes these instructive sayings to Confucius' eastern wisdom. For Huang, the fictional Charlie Chan is highly entertaining, while the real-life policeman, Chang Apana, is a Chinese-American success, whose story is worth telling. Question: According to the passage, we know that Charlie Chan _ . Answer:
Answer: was a character in books and movies based on a real detective

input with options: Read the following article and answer the question. Article: Around every Lunar New Year holiday, China becomes a country on the move. The holiday crush this year is estimated to be even heavier than before. Government officials suggest that Chinese people will take to the air, roads and railways 3.62 billion times over a 40-day period around the nation's most important holiday this year as people push their way home for family gatherings or to satisfy their new-found passion for travel. Getting tickets to all those would-be travelers is a _ challenge that tries your patience annually. And the pressure for the railway system is always the greatest. Railways are the transport of choice for low-cost long-distance travel, and that's where the ticketing system regularly falls down. Much of the criticism has focused on the railway's online purchasing system, which has been unable to keep pace with the huge demand and also failed to stop scalpers from easily getting many of the hard-to-find tickets. Railway officials believed that online sales were the fairest way to get tickets for travelers, and told reporters that the public need to be patient. While by now the railway service is far from satisfying, efforts are being made to provide online identity checks that would reduce the ticket scalping problems, and the situation is expected to get better in a few years. Meanwhile, for those traveling by car, good news is that the country's extremely expensive highway tolls will be removed for the period of the official holiday. Question: According to the text, getting tickets _ around the official holiday. Answer:
OPTIONS:
- is convenient for travelers
- costs more money
- requires great patience
- is just a piece of cake
output:
requires great patience
