Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: American researchers say drinking tea may help strengthen the body's defense system against infection. Doctors at Brigham and Women's Hospital in Boston, Massachusetts, did the study. The team studied a chemical found in black, green, oolong and pekoe tea. This chemical is an amino acid called L-theanine. The scientists say it may increase the strength of gamma delta T cells. That's the letter T, not the drink. Gamma delta T cells are part of the body's defense. First, the researchers mixed some of these cells with antigens found in the amino acid . Antigens help the body react to infection. Then the scientists added some bacteria. Within twenty-four hours, the cells produced a lot of interferon, a substance that fights infection. Cells not mixed with the antigens did not produce interferon. In the second part of the study, eleven people drank five to six cups of black tea every day. Ten other people drank the same amount of instant coffee. That is dried coffee mixed with hot water. Two weeks later, and again two weeks after that, the researchers tested the blood of all twenty-one people. They also looked at what happened when they added bacteria to the blood cells. They found that the tea drinkers produced five times more interferon after they started drinking tea. The coffee drinkers did not produce interferon. Doctor Jack Bukowski led the study. He says the antigens added to the gamma delta T cells were responsible for the increased reaction to the bacteria. He says that the study also showed that the cells were able to remember the bacteria and fight them again the next time. Earlier research already has found that tea can help prevent heart disease and cancer. Doctor Bukowski says the new study must be repeated by more people. "If the findings prove to be true," he says, "then tea drinking might also help protect against bacterial infections." He says the amino acid L-theanine could be removed from the tea and used as a drug to strengthen the body's defenses. Options: A L-theanine B Gamma delta T cells C interferon D bacteria Answer: A L-theanine Question:

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: "Mom, you should put some of your things away. The house should be safe for the baby," said my son Mark as he walked upstairs with his wife and fifteen-month-old Hannah. They visited us for the Thanksgiving holiday. After driving all day from Salt Lake to Ft. Collins, his temper showed. "That one finger rule may work with other kids, but never Hannah," he insisted. When my three granddaughters first moved into our house three years ago, my friend offered me her secret to behave grandchildren. "Teach them the 'one finger rule'." All of her five grandchildren learned it at a young age and it proved to also work well with mine. I picked up my granddaughter and said, "Well, Mark, just watch." I hugged her and walked all around the great room. "Hannah, you may touch anything in this room you want, but, you can only use one finger." I showed the technique by touching my forefinger to the sculpture. Hannah followed my example. "Good girl. Now what else would you like to touch?" She stretched her finger toward the lamp. I allowed her to touch everything in sight, plants, glass objects, TV, VCR, speakers, etc. If she started to grab , I gently reminded her to use one finger. She always obeyed. However, Hannah, an only child, possessed a more adventurous personality. Her father predicted it would prevent her from accepting the "one finger rule". During their four-day stay, we aided Hannah in remembering "one finger rule". She learned quickly. Months later, my husband and I drove to Salt Lake. I watched Mark continue to practice the one finger rule. I smiled happily each time he asked Hannah to touch with "one finger". Options: A ask the author to look after Hannah for them B visit the author for the Thanksgiving holiday C help Hannah practice the "one finger rule" D find a safe place for Hannah to live in Answer: B visit the author for the Thanksgiving holiday Question:

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Why I Don't Spare "Spare Change" "Poor but honest." "The deserving poor. " These words always come to my mind when I think of "the poor. " But I also think of people who, perhaps through alcohol or drugs, have ruined not only their own lives but also the lives of others in order to give way to their own pleasure. Perhaps alcoholism and drug addiction really are "diseases. " as many people say, but my own feeling-based, of course, not on any serious study-is that most alcoholies and drug addicts belong to the "undeserving poor. " And that is largely why I don't give spare change to beggars. But surely among the street people there are also some who can rightly be called "deserving." Deserving what? My spare change? Or simply the government's assistance? It happens that I have been brought up to believe that it is proper to make contributions to charity , but if I give some change to a beggar, am I making a contribution to charity and thereby helping someone, or, am I perhaps simply encouraging someone not to get help? Or, maybe even worse, am I supporting a cheat? If one believes in the value of private charity, one can either give to needy people or to charitable organizations. In giving to a beggar one may indeed be helping a person who badly needs help, but one cannot be certain that one is giving to a needy person. In giving to an organization, on the other hand, one can feel that one's money is likely to beused wisely. True, facing a beggar one may feel thatthis particular unfortunateperson needs help atthis moment-a cup of coffee or a sandwich-and the need will not be met unless I put my hand in my pocket right now. But I have come to think that the beggars whom I meet can get along without my spare change, and indeed perhaps they are actually better off for not having money to buy alcohol or drugs. I know nothing about these beggars, but it's my impression that they simply prefer begging to working. I am not generalizing about street people. I am talking about the people whom I actually meet. That's why... Options: A They should be given a cheek-up. B They really need money to live. C They have no pleasure in life. D They are not worth helping. Answer: D They are not worth helping.
