Read the following article and select the best answer. Article: Recently, one of my best friends, whom I'd shared just about everything with since the first day of kindergarten, spent the weekend with me. Since I moved to a new town several years ago, we'd both always looked forward to the few times a year when we could see each other. Over the weekend, we spent hours and hours, staying up late into the night, talking about the people she was hanging around with. She started telling me stories about her new boyfriend, about how she experimented with drugs and was into other bad habits. I was blown away! She told me how she had been lying to her parents because they didn't want her around him. I tried to convince her that she was ruining her future and heading for big trouble. But she didn't believe me. Her self-respect seemed to have disappeared. I just couldn't believe that she really thought it was acceptable to hang out with such a loser. By the time she left, I was really worried about her. It had been so discouraging, and I had come close to telling her several times during the weekend that maybe we had just grown too far apart to continue our friendship--but I didn't. I put the power of friendship to the ultimate test. We'd been friends for far too long. I had to hope that she valued me enough to know that I was trying to save her from hurting herself. I wanted to believe that our friendship could conquer anything. A few days later, she called to say that she had thought long and hard about our conversation,and then she told me that she had broken up with her boyfriend.I just listened on the other end of the phone with tears of joy running down my face. It was one of the truly rewarding moments in my life. Never had I been so proud of a friend. Question: It can be inferred that the girl _ . - knew she was in danger. - took the author seriously. - lost hope of a bright future. - used to quarrel with her parents.

Read the following article and select the best 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... Question: Why do newborn infants whose mothers use humor to deal with stress have fewer infections? - Because they don't often get upper respiratory infections. - Because they are stronger since they were born. - Possibly because of the higher levels of immunoglobulin A in their breast milk. - Because their mothers take better care of them.
