question:
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.
answer:
A

Article: I walked alongside my father, clutching his right hand.All my clothes were new: the black shoes, the green school uniform, and the red cap.They did not make me happy, however, as tins was the day I was to be thrown into school for the first time.I tried in vain lo convince him that I did nothing wrong all the way, but it didn't help.

" "My father," I whispered. ''My father's dead, " he said simply. I did not know what to say.The gate was now closed.Some of the children burst into tears.The bell rang.A lady came along, followed by a group of men.The men began soiling us into ranks.We were formed into an intricate pattern in the great courtyard surrounded by high buildings. Well, it seemed that my misgivings had had no basis.From the first moments I made many friends and fell in love with many girls.I had never imagined school would have this rich variety of experiences. We played all sorts, of games.In the music room we sang our first songs.We also had our first introduction to language.We saw a globe of Earth, which revolved and showed the various continents and countries.We started lean-line numbers, and we were told the story of the Creator of the universe.We ate delicious food, took a little nap, and woke up to go on with friendship and love, playing and learning. Our path, however, was not totally sweet and unclouded.We had to be observant and patient.It was not all a matter of playing and fooling around. Rivalries could bring about pain and hatred or give rise to fighting.And while the lady would sometimes smile, she would often yell and scold.Even more frequently she would resort to physical punishment. The bell rang, announcing the passing of the day and the end of work.The children rushed toward the gate, which was opened again.I said goodbye to friends and sweethearts and passed through the gate.I looked around but found no trace of my father, who had promised to be there.I stepped aside to wait.
