Write a multi-choice question for the following article, with the given choices and answer: Article: If you didn't look at them, they weren't there, right? On seeing those in rags on the corner, I only wanted the light to turn green fast enough so that I wouldn't have to keep pretending not to see them. Then, one day, as I was holding the hand of my best friend Jane who was young but dying of breast cancer, she told me that she made every moment count by slowing down and by seeing everything . I held her hand for five years and then she passed away. She did teach me something. It took a while for her words to really sink in. I can be a slow learner. I started by seeing everything, and focused on their presence. One day I saw a Vietnam veteran . I asked him what would make his day. "A hot cup of coffee," he told me. I bought him a cup of coffee, a stack of pancakes, some eggs, and so on. After our meal together, I asked him if there was anything else that would make his life a bit easier. "A new pair of socks, "he said. Socks, really? I actually happened to be wearing a nice pair of wool hiking socks at that very moment. I told him that I wanted to give him the pair I was wearing if he would accept it. Finally he agreed. We sat down on a bench, and he started to first take off his boots, and then remove the black socks that had once been white off his feet. I think a layer or two of skin might have come off with them. Taking his new pair of socks, he held the socks up to his cheeks and said they were warm and smelled as good as me, pools of tears in his eyes. Such a simple luxury I used to take for granted. Now I always have an extra pair with me in my car. They are always my best pair, just waiting to be given away. Options: A To decorate his car. B To sell it to others. C To keep it for a change. D To donate it to a needy person. Answer: D To donate it to a needy person. Question:

Write a multi-choice question for the following article, with the given choices and answer: Article: A small dog should be _ after eating a handful M&M's, at least according to conventional wisdom. But watching "Moose", a friend's five-pound Chihuahua, race around a living room after his sweet snack makes one wonder: Is chocolate truly poisonous to dogs? Dogs and humans have similar tastes. But unlike humans, our companions experience dangerous effects from eating chocolate --it can poison them and in some cases is fatal. Chocolate's danger to dogs depends on its quality. Chocolate is processed from the bitter seeds of the cocoa tree, which contain a family of compounds known as methylxanthines . This class of substances includes caffeine and the related chemical theobromine . Chocolate contains a significant amount of theobromine and smaller amounts of caffeine. These chemicals can cause a dog's heart to race up to twice its normal rate, and some dogs may run around as if "they drank a gallon of espresso ," according to Hackett. Dogs are capable of handling some chocolate, but it depends on the animal's weight and the type of chocolate it eats. Unsweetened baking chocolate contains more than six times as much theobromine as milk chocolate, although amounts vary between cocoa beans as well as different brands of chocolate. Less than four ounces of milk chocolate is potentially fatal for Moose and other small dogs. Around every confection-centered holiday -- Valentine's Day, Easter and Christmas -- at least three or four dogs are hospitalized overnight in the animal medical center at Colorado State. But in 16 years, Hackett has seen just one dog die from chocolate poisoning, and he suspects it may have had an underlying disease that made it more exposed to chocolate's heart -racing effect. Options: A the poisoning of Moose B the compounds of different chocolates C a handful M&M's chocolate is poisonous D the relation between methylxanthines and chocolate poisoning Answer: D the relation between methylxanthines and chocolate poisoning Question:

Write a multi-choice question for the following article, with the given choices and answer: Article: "I drink caffeine to stay awake. It has positive effects on me. I'm healthy, and there's nothing wrong with me," said Sarah Green, a freshman, who consumes many caffeine drinks to stay awake in completing the many tasks in her busy schedule. Caffeine is known to have many positive and negative consequences, and now that there might be an additional positive effect may have been discovered. A study suggests that a skin lotion containing caffeine, which is also found in green tea, may reduce the risk of skin cancer. Two lotion tests were conducted on hairless mice that were exposed to high levels of ultraviolet radiation . As a result, the lotion reduced the number of tumors each mouse developed. Unlike sunscreen , the new lotion is applied after exposure to the ultraviolet rays. Rays from the sun can cause genetic changes in the skin that can lead to skin cancer. Caffeine obstructs this action and causes the diseased cells to kill themselves. "I know that caffeine has been found in certain drinks and it causes increased activity of the nervous system, and increased blood pressure on blood vessels . I don't know of any positive effects of caffeine," health teacher Montego Estes said. Caffeine, found commonly in tea, coffee and soft drinks, provides people with an increase in energy. Half of all American adults consume more than 300 milligrams of caffeine per day. Caffeine is addictive because it uses the same mechanisms as amphetamines , and cocaine and heroin to excite the brain. "This new cream doesn't sound to me as though it would work," junior David Bobbit said, "Caffeine seems to have more negative effects than positive ones." Skin cancer is the most common of all cancers in the US. About one million cases will be diagnosed in the country this year. There will be more than 88,000 new cases of melanoma , the disease's deadliest form of skin cancer. Options: A Sarah Green knows caffeine can protect her from skin cancer B Exposure to ultraviolet rays is always blamed for skin cancer C Caffeine will be used in medicine to treat skin cancer patients soon D In a way, the study on caffeine is good news for many Americans Answer: D In a way, the study on caffeine is good news for many Americans Question:
