Article: Dear Betty, My roommate's family wants me to celebrate Thanksgiving Day with them in their home. I accepted the invitation, and I'm excited about going, but I'm a little nervous about it, too. The social customs in my country are different from those here, so I'm a little worried about making mistakes. Should I bring a gift, such as candy or flowers? Should I arrive on time or a little late? At the dinner table, how can I know which fork or knife to use? How can I let the family know that I'm thankful for their kindness? Yours, Knowing Nothing Dear Knowing Nothing, It's a good idea to bring a gift when you go to a dinner party. Flowers are always welcome, or you can bring a bottle of wine if you know the family drink it. You should arrive on time or five to ten minutes late. Don't get there early. If you are going to be more than fifteen minutes late, you should call and tell them. Try to relax at the dinner table. If you don't know how to use the right fork, knife or spoon, just watch the other guests, and follow them. If you still have no idea of what to do, don't be shy about asking the person next to you; it's better to ask them than to be silently uncomfortable and nervous. If you like the food, say so. Of course, you'll thank the host and hostess for the meal and for their kindness. It's also a good idea to send a card to thank them the day after. Yours, Betty Question: Betty does NOT advise Knowing Nothing to _ . Yes or no, is the answer "keep silent at table"?
Yes

Article: While Errenzhuan has gained in popularity over the past few years, not least as a result of comedians such as Xiao Shenyang, so has the Western equivalent of the ancient art form - stand-up comedy. Stand-up comedy differs from Errenzhuan. It normally features a single person on stage, as opposed to a duet. Although music is sometimes included, other features such as dance are a lot rarer. Instead, stand-up comedy is usually just one person, a microphone and the audience. Whether the comedian _ or has people in fits of laughter is all down to his or her skill. I never used to like the idea of stand-up comedy. It seemed too forced for me. "I'll laugh when I feel like it," I thought. I don't want to have someone stand in front of me, pressuring me to chuckle. Stand-ups also have a reputation for picking on their audience. If you sit close to the front of the stage, you'd better be careful. One cough or wrong move, and the comedian will pounce. Before long, you are the focus of all the jokes. But a couple of years ago, I went to see a comedian who changed my opinion - British stand-up Stewart Lee. He is not hugely famous, but instead of jokes, he told very funny, often long stories about his life. His delivery was dry, and he had a very quick wit. I soon began to appreciate just how hard it is to make people laugh on demand. The great thing about stand-ups is that you hardly ever see two that are the same. There are so many different approaches, and people from all sorts of backgrounds can make people laugh in different ways. For example, one of the most popular stand-up comedians in the world is Chris Rock. Rock is African-American, and uses his race, and the problems he faces because of it, as material for his routines. He turns a topic that is normally serious into something funny. "A black C student can't be a manager at Burger King, meanwhile a white C student just happens to be the President of the United States," he once joked about racism in the United States during George Bush's presidency. That is... Question: The passage is mainly about _ . Yes or no, is the answer "western stand-up comedy"?

Yes

Ques: Article: Think about the longest elevator ride that you've ever taken. Whether you rose five or 100 floors, it probably took less than a few minutes. Now imagine riding in an elevator higher and higher as it climbs for nearly a day. When you reach the top floor, prepare for views that are really out of this world. You'll be in space! Space elevators might sound like a crazy idea, but they're something scientists have been working on for decades. At the moment, riding in a capsule is the only way ordinary people can get to and from space. But those rides are very expensive---about $ 25 million per person per flight. Now scientists are making efforts to reduce the expense of those rides. Researchers are still figuring out the details about how a space elevator might work. One idea is stretching a very long cable -- more than 37,000 kilometers -- up to space from the earth's equator . Objects in space above the equator orbit (......) the earth at the same speed that our planet turns. A weight on the end of the cable would stretch it tight. An elevator tied to the cable could use _ to climb up and down. The only problem is that besides being long, this cable must also be very strong. Storms, including hurricanes might break it. One way to solve this problem is to stretch the cable from the moon instead of from the earth. Airplanes designed to climb higher than a typical jet might take off from the earth and link up with the cable, which would be held in place by the pull of gravity from the earth. An elevator car waiting there would then take riders the rest of the way to the moon. Fueled by solar power, the elevator could transport people and materials without much expense or effort per ride. Question: Why have scientists been working on space elevators? Yes or no, is the answer "To make trips to space cheaper."?
Ans: Yes

Ques: Article: The whole world is helping tsunami victims. Students in the U.S. are also taking part. A friend of mine suggested that we organize a relief effort for the victims. We are officers of the American Red Cross at Yale (I'm the chairperson). After sending a letter to the other members of the Red Cross, I received a large number of responses from students interested in helping. We decided to organize a charity concert to raise money for tsunami-ravaged areas. All ticket earnings will go directly to our parent organization, the American Red Cross. Currently, we're in the process of inviting Yale's numerous song, dance, and chamber music groups to perform at the concert. So far, we've had a great response from these groups and volunteers have continued to pour in with their ideas and feedback. When I checked my inbox this morning, I had 56 tsunami fundraiser-related emails waiting for me. Although, everyone is still on winter vacation and away from school, we have the Internet to link up Yalies from around the globe. We share ideas not on the latest video games, but on how best to provide help. The Red Cross at Yale is not alone in its aid effort. Student organizations across campus are working hard to raise funds and provide help to those who need it. Yale's South Asian Society (SAS) and the Asian American Students Alliance (AASA), which is an umbrella organization for many other groups including the Sri Lankan Students Association, are organizing charity dinners. The food will be donated by restaurants from around campus. Every last penny of the earnings will be donated to a non-profit organization providing aid to South Asia. After some discussion with the SAS and AASA, our groups have decided to plan our two events together. Students can attend the benefit dinner then go to the charity concert. There is no doubt in my mind that both events will have a fantastic turnout. Question: The author keeps in touch with Yalies to _ . Yes or no, is the answer "ask them to offer help"?
Ans:
No
