[Q]: Article: On a Friday night, a poor young artist stood at the gate of the New York railway station, playing his violin. The music was so great that many people stopped to put some money into the hat of the young man. The next day, the young artist came to the same place, and put his hat on the ground gracefully. Different from the day before, he took out a large piece of paper and laid it under his hat. Then he began to play the violin. It sounded more pleasant than ever. Soon he was surrounded with people who were attracted by the words on that paper. It said, "Last night, a gentleman named George Sang put an important thing into my hat by mistake. Please come to claim it soon." After about half an hour, a middle-aged man rushed through the crowd to the violinist and said, "Yes, it's you. I knew that you were an honest man and would certainly come here." The young violinist asked calmly, "Are you Mr. George Sang?" The man nodded. The violinist asked, "Did you lose something?" "It's a lottery ticket," said the man. The violinist took out a lottery ticket on which George Sang's name was seen. "Is it?" he asked. George nodded and took the lottery ticket and kissed it, then danced with the violinist. The violinist was a student at an arts college and had planned to attend advanced studies in Vienna. Later his classmate asked the violinist, "At that time you needed money to pay the tuition and you had to play the violin in the railway station every day to make money. Why didn't you keep the lottery ticket for yourself?" The violinist said, "Although I don't have much money, I live happily. But if I lose honesty I won't be happy forever." Through our lives, we can gain a lot and lose so much. But being honest should always be with us.

[Q]: Article: Certainly no creature in the sea is stranger than the common sea cucumber . All living creatures, especially human beings, have their features, but everything about the little sea cucumber seems unusual. What else can be said about an unusual animal that eats mud, feeds almost continuously day and night but can live without eating for long periods, and can be poisonous but is considered eatable? For some fifty million years, in spite of all its strange features, the sea cucumber has lived on its diet of mud. It is adaptable enough to live attached to rocks by its tube feet, under rocks in shallow water, or on the surface of mud flats. Common in cool water on both Atlantic and Pacific shores, it has the ability to suck up mud or sand and digest whatever nutrients are present. Sea cucumbers come in a variety of color1s, ranging from black to reddish-brown to sand-color1 and nearly white. One form even has brilliant purple tentacles . Usually the creature are cucumber-shaped--where their name comes from--and because they live in rocks, this shape, combined with flexibility, enables them to press into crevices where they are safe from animal eater and ocean currents. Although they have greedy desire for food, eating day and night, sea cucumbers have the ability to become still and live at a low metabolic rate--feeding a little or not at all for long periods, so that the living things in the ocean that provide their food have a chance to increase by a large amount. If it were not for this natural ability, they would swallow all the food available in a short time and would probably starve themselves out of existence. But the most impressive thing about the sea cucumber is the way it defends itself. Its major enemies are fish and crabs. When attacked, it forces all its internal organs in its body out into water. It also removes attached structures such as tentacles. The sea cucumber will get rid of its organs and grow itself again if it is attacked or even touched; it will do the same if the surrounding water temperature is too high or if the water becomes too polluted.
Question: According to the passage, why is the shape of sea cucumbers important?
Options: (A) It helps them to protect themselves from danger. (B) It makes it easier for them to move through the mud. (C) It makes them attractive to fish. (D) It helps them to digest their food.
