Did you oversleep on a weekday and fear you'd get into trouble at the office? In any case, you know what it feels like to feel fear. But one woman doesn't the woman, code-named "UM", gave her first-ever interview after years of being studied by a team of researchers. The woman is given a code name because the researchers want to protect her from anyone who would take advantage of her inability to feel afraid. UM can't tell you what fear is because she's never experienced it. "I wonder what it's like to actually be afraid of something," she said. The formal name for the disease is Urbach-Wieth disease, which is characterized by a hoarse voice,small bumps around the eyes, and calcium deposits in the brain. In the case of UM,the disease has transformed the part of her brain that controls the human response to fear. In the interview, UM talks about an event in her life where she was held at knifepoint and gunpoint, "I was walking to the store,and I saw a man on a park bench.He said. "Come here,please," so I went over to him. He grabbed me by the shirt,put a knife to my throat and told me he was going to cut me. I told him, "Go ahead and cut me," I wasn't afraid at all. And for some reason,he let me go." Doctors who have been studying UM's condition for years have been trying different things that could strike fear into her. They finally figured something out--increasing UM's carbon dioxide levels.Extra carbon dioxide concentration in the blood is known to cause fear and panic in health individuals. Increasing UM's carbon dioxide levels did manage to give her a fright. Question: The text starts by _ . - challenging the reader - solving daily problems - listing situations - giving explanations

Read the following article and select the best answer. Article: Good health is the most precious thing in the world .When you have got it, you never think about it. When you haven't got it , you think about it all the time. Our biggest enemies are not terrible diseases. We are our own biggest enemies because we sometimes destroy our own good health. Some of us eat too much, drink too much and smoke too much. And though our reason tells us we should control ourselves, we find it difficult. The fact is that most human beings need stimulation. Who doesn't enjoy a drink after a busy day? Only a smoker knows the pleasure of a cigarette with a cup of coffee. The danger is when these innocent pleasures run our lives and so destroy our health. When you find yourself eating between meals or eating too much rich food, when you can only keep yourself going by taking frequent drinks or by smoking one cigarette after another, then it's time to stop and think what you might be doing to yourself. The funny thing is that when we don't control ourselves, simple pleasures are no longer simple pleasures. All right, I know what you're thinking. You're probably saying: "It's all very well for him to talk, but I can't help myself. I need that extra bit of food, that extra drink, that extra cigarette. Life has so many pressures that I can't manage without them." But I'm saying you can help yourself. Not only that you must help yourself. Because if you don't help yourself, no one else can. So be your own best friend . Question: "I can't help myself" means _ . - I can't do it myself - I must ask someone for help - I can't control myself - Do help me , please
I can't control myself
