Q: Article: The opening of the Sherlock Holmes Museum to the public on March 27, 1990, was an event that should have happened several decades ago. Baker Street is, after all, one of the world's most famous streets because of its long association with the great detective. Thousands of people all over the world write to Sherlock Holmes, they form clubs and societies in his honor, and they celebrate his anniversaries. Now it is also possible to see where and how he lived in Victorian times! Here visitors will recognize familiar objects mentioned in the stories. You can take as many photographs as you want (the maid will be pleased to assist) and when you are ready to leave, a ride home in a horse-drawn carriage will complete your 19th century experience! Sherlock Holmes and Doctor Watson lived at 221b Baker Street from about 1881 to 1904. Apartment 221b was on the first floor of a lodging house, which they rented from a Mrs Hudson. The famous study that Holmes and his friend Dr Watson shared for almost 25 years is on the first floor overlooking Baker Street. We know from Doctor Watson's descriptions that their sitting room overlooking Baker Street was "illuminated(, ) by two broad windows" and that it was quite small. Doctor Watson's bedroom was on the second floor next to Mrs Hudson's room and it overlooked an open yard at the back of the house. These rooms are used today for exhibits, where center stage is taken by a magnificant bronze bust of Mr Holmes. Visitors can browse through literature, paintings, photographs and newspapers of the period. Memorabilia from the adventures and a selection of letters written to and from Mr Holmes are also on display. The museum's large and attractive souvenir shop is located on the ground floor. Here you will find a unique collection of gifts, objects of art, figures, busts, prints, books, playing cards, T-shirts, -novelties of every description available exclusively to museum visitors.

Q: Article: After my brother died in an accident, my mother was in deep sadness. I was only a four-year-old girl at the time, but I still understood the sudden shift in my mom's attitude towards safety. Suddenly everything around us was potentially dangerous. Overnight, the world had gone from a playground to a dangerous zone. I grew up with a lot of limits and rules. I couldn't walk home from school by myself, even though everyone I knew already did. I couldn't go to summer camp because what if something happened to me? As I got older, the list of things of fear got longer. My whole life was divided into "things you should avoid", and "things you needed to do in order to have a good, long life." I became a natural worrier. I worry about things like getting cancer, losing my wallet, car accidents, earthquakes, and losing my job -- disasters big and small, real and imagined. The funny part is that you'd never know it by looking at my life. In fact, I've developed a rule for myself: If it scares me, then I have to do it at least once. I've done lots of things that my mom would have worried about: I've ridden a motorcycle; I've traveled --a lot. I've performed stand-up comedy, and I'm planning my second wedding. There's something else I don't usually talk about, but it's a cornerstone in my belief: When I was 14, my mother died suddenly in a car accident. At my mom's funeral I remember making a choice. I could either live out the rest of my life trying to be "safe" or I could be brave enough to live out a fulfilling, exciting and, yes, sometimes dangerous life. I worry that I may have betrayed my mother by writing her in this light, but she has been a driving force in my life and, in the end I think she would have been proud of me. Courage isn't a natural character of human beings. I believe that using courage is like developing a muscle. The more often I do things that scare me or that make me uncomfortable, the more I realize that I can do a lot more than I originally thought I could do. Even though I inherited my mother's cautious nature. I've also come to believe that fear can be a good thing, if we face it. Believing that has made my world a less scary place.
Question: In the writer's childhood, the limits and rules were used to _ .
Options: (A) improve her behavior (B) develop her independence (C) be in memory of her dead brother (D) protect her from possible danger

A: D

Q: Article: The best swimmers tend to be tall and thin with long arms, long legs, long feet, and long hands. The size of their hands gives them great "water grasp", and only a very small hand movement keeps them afloat. They also have great strength, endurance, insulation against heat loss while in water below body temperature, thus better energy conservation, low resistance when in the water, and swimming stroke mechanics . Part of the reason why some people are better swimmers than others has to do with body density. The average person's body density is slightly less than that of water. Muscle has greater density than fat. Therefore, very muscular people tend to be poor at staying afloat. Bone has greater density than fat. Therefore, very skinny people tend to be poor at staying afloat. Good buoyancy is not necessarily the most important factor in good swimming, but it certainly helps. For example, great competitive swimmers--tall, thin, and usually more muscular than average--tend to have greater body density than average and less buoyancy. Many would not float very well if they remained motionless in the water. Their much greater "water grasp" makes up for it. www.ks5u.com The average woman contains a higher proportion of fat in her body than the average man, and the average man contains a higher proportion of muscle in his body than the average woman. Therefore, in general, women are better floaters than men. Compared with other competitive sports, the performance of women is closer to that of men in competitive swimming.
Question: What can we learn from the passage about body density?
Options: (A) Higher body density reduces swimming ability. (B) A person's body density decides one's swimming ability. (C) Fat people can always swim faster than thin people. (D) People with a lower proportion of muscle can hardly swim.

A:
A
