Write a multi-choice question for the following article, with the given choices and answer: Article: We have seen that humor and laughter positively influence our body in many ways, but little research has been done on whether a better sense of humor actually helps keep you from getting sick. However, since people with a better sense of humor have higher IgA levels, and since research has shown that those with higher levels of salivary IgA are less likely to get colds or be infected with Streptococcus, humor should reduce the frequency of colds. The only study to directly examine this question found that the impact of one's sense of humor upon colds depends on the kind of sense of humor you have. It was only individuals whose sense of humor took the form of seeking out and appreciating humor who had fewer and less severe colds/flu than their low humor counterparts. Surprisingly, those whose sense of humor took the form of initiating humor more often did not have fewer or less severe colds/flu. The researchers argued that being a person who likes to tell jokes or otherwise initiate humor takes them into more frequent contact with other people, which serves to expose them to infectious agents more often, robbing them of the advantage that a more active sense of humor otherwise offers. Obviously, more research is required to clear up this confusing picture. The importance of active use of one's sense of humor in producing humor's health benefits was confirmed in another study in an unusual way. It found that among a group of mothers with newborn infants, those who actively used humor to cope with the stress in their lives had fewer upper respiratory infections and their infants also had fewer infections. This seemed to be because these mothers had higher levels of immunoglobulin A (A) in their breast milk. Among adults, if we look at bodily symptoms alone, independent of any diagnosed illness, there is some evidence that individuals who have more negative reactions to humor report more bodily symptoms and complaints. Students complaining of cardiovascular symptoms and gastroenterological symptoms also have... Options: A a medicine B enzyme C factor D measure Answer: B enzyme Question:

Answer: According to the passage, IgA is _ .

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: I recall my mother's voice which called me to order, and often ended with some strong proverb to express the gravity of the wrong done. It was common practice for my mother to send me off soul-searching with a proverb. Of the many interactions I had with my mother those many years ago, one stands out with clarity. I remember the occasion when Mother sent me to the main road, about twenty yards away from the farmhouse, to invite a passing group of seasonal work-seekers home for a meal. She instructed me to take a container along and collect dry cow dung for making a fire. I was then to prepare the meal for the group of work-seekers. The thought of making an open fire outside at midday, cooking in a large three-legged pot in that high heat, was enough to upset even an angel. I did not manage to hide my feelings from my mother, and after serving the group, she called me to the balcony, where she usually sat to attend to her sewing . Looking straight into my eyes, she said, "Tsholofelo, why were you so unhappy when I requested you to prepare a meal for those poor people?" Despite my attempt to deny her allegation , and using the heat of the fire and the sun as an excuse for my alleged behavior, Mother, giving me a firm look, said, "A foot has no nose." It means, "You can't detect what trouble may lie ahead of you." Had I denied the group of people a meal, it may have happened that, in my travels some time in the future, I found myself at the mercy of those very individuals. As if that was not enough to shame me, Mother continued, "A person is a person because of another person." Options: A quoted proverbs when she was talking with others B asked Tsholofelo to read more proverbs C collected proverbs in her spare time D used proverbs to teach Tsholofelo Answer: D used proverbs to teach Tsholofelo Question:
A: We learn from the passage that Tsholofelo's mother often _ .

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Special trees that grow faster, fight pollution, produce better wood, and even sense chemical attacks are being planted by scientists in the US. When 40 per cent of Hawaii's US$14 million-a-year papaya industry was destroyed by a virus five years ago, work began on creating genetically engineered trees. Researchers successfully introduced seeds that were designed to resist the virus.Since then, more and more people have been testing genetically engineered trees.Some researchers put special bacteria into trees to help them grow faster and produce better wood.Others are trying to create trees that can clean polluted soil.Meanwhile fruit farmers are looking for trees that are strong enough to resist worms, and paper companies want trees that produce more wood and therefore more paper. The Pentagon even gave the researchers US$500,000 this year after they developed a pine tree that changes its colours if it senses a chemical attack.So far, the poplar, eucalyptus , apple and coffee trees are among those being engineered.All this can be done today because we have a better understanding of tree genomes . However, some people fear that the genetically engineered trees will cause dangerous results.They are worried that the new trees will breed with natural species and change the balance of the forest environment. "It could be destructive," said Jim Diamond, an environmentalist. "Trees are what is left of our natural environment and home to many endangered species." But researchers insist that science could give nature a fighting chance against both natural and man-made dangers.They hope to answer the critics by stopping the new trees from breeding, so their effect on the environment can be controlled. Options: A Tree genomes are mapped out so scientists know how to improve trees. B Great numbers of trees have been lost due to attacks by viruses. C Researchers successfully introduced seeds designed to resist the virus. D They think science could give nature a fighting chance against both natural and man-made dangers. Answer: B Great numbers of trees have been lost due to attacks by viruses. Question:
Answer: What caused the American scientists to work on special trees?
