I'm taking a test and have to guess the right answer to the question after the article. Article: The Lunar New Year, which starts in late January this year, is the most important festival for Chinese people as most of them drop any business at hand to go back to their hometown to see their families. It is a tradition that has been cherished since ancient times, but as social mobility increases in modern times, the road to family reunions has become very uneasy. It is not the higher travel costs, nor the expected big spending on gifts and other festival items, but the train ticket that has driven many travelers mad. I've heard some colleagues complain that they have tried every means to secure a train ticket, only to find it a mission impossible. Some of them have turned to the latest software to aid online booking; others have sought help from friends to increase the possibility of successful booking. No doubt chunyun, the Spring Festival travel season, is the largest-scale annual human migration in the world. Last year, 220 million passengers traveled by train during the Spring Festival season, which usually lasts 40 days. It is a huge jump from 10 years ago, when the number was 128 million. With the big sudden increase in demand, the railway company has increased investment in railway construction; still, it cannot bridge the supply gap, leading to fierce public complaints and criticism. Admittedly, it is almost impossible for the railway company to suddenly improve its capacity to meet the explosive demand during the Spring Festival holiday. Moreover, any temporary increase in capacity would become unnecessary after the holiday and mean great commercial losses during the off season. What the company can reasonably do is gradually improve its capacity while focusing on better distribution of its existing resources during the special peak season. At any rate, however, the problem cannot be solved overnight. Question: Compared with ten years ago, the percentage of passengers last year increased by _ . Options: A: 40% B: 58% C: 71% D: 83%

I'm taking a test and have to guess the right answer to the question after the article. Article: For many in the prefix = st1 /United States, Arab-Americans are an invisible part of the population. Though Arab-Americans as a community have made great contributions to American society in fields from literature to politics to medicine, many Americans know very little about Americans of Arab backgrounds. Arab history in the United Statesgoes back to the late 1800's when large numbers of Arab immigrants first began making their journey to a land known simply as "Amreeka". Historians generally describe Arab immigration to Americain two waves. The first wave took place between 1860 and 1924.The first wave consisted of Lebanese and Syrian, and some Egyptian immigrants. These new immigrants, who were mostly Christian, came toAmericain search of better opportunities. Even the doomed Titanic, which set sail forAmericain 1912,had close to a hundred Arab passengers aboard. The majority of Arab-Americans today are descendents of the first wave of immigrants; they are the third or more generation Americans. The second wave of immigrants followed after World War II, caused by political unrest in the Middle East. This second wave of immigrants consists of mainly Arab Muslims and continues to this day. Arab-Americans make up 3 million of the population in the United States, according to demographers. And quite different from popular belief, 64% of them are American-born. 82% percent of Arab-Americans are US citizens. Arab-Americans are beyond the national average in both education and income. Education is important among Arab-Americans; 82% have high school diplomas, 36% have bachelor's degrees or higher, and 15% have graduate degrees. The average income among Arab-Americans is $39580, which is higher than the USaverage. Question: The writer of this passage mentioned Titanic _ . Options: A: to tell us that taking ship at that time was dangerous B: because Titanic became a well-known disaster C: to show us there were many Arabs flocking into Americaat that time D: to inform us that Arabs are brave enough

I'm taking a test and have to guess the right answer to the question after the article. Article: She might not be paid, but Carnegie Mellon University's newest staff member does all that a typical receptionist can do: give directions, answer the phone -- and even gossip about her life. University officials revealed what it considers to be the world's first robot receptionist with a personality of her own. The blond receptionist, named "Valerie," puts on a headset and interacts with people by talking about her boss, her psychiatrist and her dream. Valerie, the roboceptionist, sits in a custom-made booth at the entrance of a computer science hall. With her ability to distinguish motion, she greets visitors as they come near. Type in a question on a keyboard and she gives directions around the Pittsburgh campus and provides visitors information about the weather. More than that, she tells stories about her life. From her booth, passers-by often can hear her talking on the phone. She recognizes when someone is in front of her and remembers their characteristics. She can change between tasks from talking on the phone to answering a question. Valerie, however, does have her limit. She is a drum-shaped mechanical device with a digitally lively face that appears on a computer display. Visitors have to type on a keyboard to communicate with her. And she understands only simple questions. Eventually her creators would like to install face recognition so people don't have to insert an identity card for her to remember them. And people won't have to type their questions on a keyboard if they can solve the problem of voice recognition in a crowded hall. Valerie will tell the story of a robot living in a human world. Question: Which would be the best title for this passage? Options: A: Robot Receptionist Gets a Job. B: The Future Receptionist. C: What Can Robots Do for Us? D: Robot Staff.
