Read the following article and select the best answer. Article: Happiness is contagious , as researchers reported on Thursday. People with the most social connections -- spouses, friends, neighbors and relatives -- were also the happiest, the data showed. "Each additional happy person makes you happier," Christakis said. "Imagine that I am connected to you and you are connected to others and others are connected to still others. It is this fabric of humanity, like an American patch quilt." Each person sits on a different colored patch. "Imagine that these patches are happy and unhappy patches. Your happiness depends on what is going on in the patch around you," Christakis said. "It is not just happy people connecting with happy people, which they do. Above and beyond, there is this contagious process going on." And happiness is more contagious than unhappiness, they discovered. "If a social contact is happy, it increases the likelihood that you are happy by 15 percent, " Fowler said. "A friend of a friend, or the friend of a spouse or a sibling , if they are happy, increases your chances by 10 percent," he added. A happy third degree friend -- the friend of a friend of a friend -- increases a person's chances of being happy by 6 percent. "But every extra unhappy friend increases the likelihood that you'll be unhappy by 7 percent," Fowler said. The finding is interesting and it is useful, too, Fowler said. "Among other benefits, happiness has been shown to have an important effect on reduced mortality , pain reduction, and improved cardiac function. So better understanding of how happiness spreads can help us learn how to develop a healthier society," he said. The study also fits in with other data suggested in 1984 that having $ 5,000 extra increased a person's chances of becoming happier by about 2 percent. "A happy friend is worth about $ 20,000," Christakis said. Question: What does Christakis mean by saying "A happy friend is worth about $ 20,000"? - A happy friend can help you bring in a wealth of $ 20,000. - A happy friend is a wealth which is worth about $ 20,000. - A happy friend increases your chances of being happy by 2%. - A happy friend increases your chances of being happy by 8 %.
A happy friend increases your chances of being happy by 8 %.

Question: Read the following article and select the best answer. Article: I regularly train at a local boxing gym and I'm lucky enough to meet an amazing man, Adrian Charter. Adrian comes to the gym to train, just like me. The difference is, I'm 31 years old, and Adrian is 72! I watched Adrian as he was training, early on a Sunday morning, and he was hitting the punching bag harder and quicker than most men in their twenties would. Adrian was a former boxer whose last professional fight was in 1972. Even though he has stopped competing as a boxer, his discipline still makes him stick to a training rule. It simply amazed me as to how a 72-year-old man could train so hard. Believe me, boxing is one of the most difficult sports on the earth, needing much patience,skill, and effort. What surprised me even more was that a few days earlier he did some running. He ran 9 kilometers. He does this on a regular basis. For me, I can run 5 kilometers at most. When I questioned him about how he kept such discipline, he calmly replied, "It is all in my mind." I thought about it for a moment. If discipline can push a 72-year-old man to train so hard and enjoy it, could I imagine how discipline could serve every single human being on the earth? Right at this point, as you read this story, please pause and ask yourself, "What is my level of discipline?" Adrian's example told me that the power of discipline will get us to the finishing line! _ Question: The author noticed Adrian Charter mostly because Adrian Charter _ . - was a famous former boxer - was the oldest in the boxing gym - acted faster even than young people - didn't want to compete any longer
Answer:
acted faster even than young people
