Article: The red crab lives on Christmas Island in the Indian Ocean and has been found nowhere else in the world. But on its homeland it is a very significant species -- some 120 million individuals cover the rain forest floor and play a major role in determining the structure of the ecosystem. These large crabs are active during the day but prefer to stay in the shade and can die in the heat of direct sunlight. They feed on fallen leaves, seeds, fruits and flowers, recycling nutrients and helping to determine the spread and composition of native plants. Most of the year the red crabs live in the holes they dig throughout the forest. During the dry season they hide in these shelters to keep their body wet and remain there for two to three months. But when wet season returns in October or November they begin a legendary mass migration to their seaside breeding grounds, moving in color1ful wave that wash over all obstacles like roads (including special passages and some closed roads built for the red crab) and even seaside cliffs. The annual migration is also closely tied to the lunar schedule. The crabs arrive at the coast and breed at such a time that the females can produce eggs and develop them in caves for a dozen or so days before carrying them into the sea exactly when high tide turns between the last quarter and new moon. During this period sea level on the beaches varies the least and offers an easier approach, which is so important that if the weather delays the migration crabs will put off laying eggs until the next lunar month. Red crab eggs grow right away, and the young live in the sea for a month before returning to the coast, changing into air breathers, and slowly returning inland to begin the cycle once again.

Chinese New Year Celebration usually lasts for 15 days. Celebratory activities include Chinese New Feast, firecrackers, giving lucky money to children, the New Year bell ringing and Chinese New Year Greetings. Most of Chinese people will stop the celebrating in their home on the 7th day of New Year because the national holiday usually ends around that day, however celebrations in public areas can last until the 15th day of New Year. It is the money given to kids from their parents and grandparents as New Year gift. The money is believed to bring good luck, ward off monsters; hence the name "lucky money". Parents and grandparents first put money in small, especially-made red envelopes and give the red envelopes to their kids after the New Year's Feast or when they come to visit them on the New Year. They choose to put the money in red envelopes because Chinese people think red is a lucky color. They want to give their children both lucky money and lucky color.

question:
Article: The challenge to drink to the limits of one's endurance has become a celebrated part of college life. In one of the most extensive reports on college drinking thus far, a 1997 Harvard School of Public Health study found that 43 percent of college students admitted binge drinking in the preceding two weeks (Defined as four drinks in a sitting for a woman and five of a man, a drinking binge is when one drinks enough to risk health and well - being ) Experts estimate that excessive drinking is involved in thousands of student deaths a year. And the Harvard researchers found that there has been a dramatic change in why students drink. 39 percent drank "to get drunk" in 1993, but 52 percent had the same objective in 1997. "What has changed is the across - the - board acceptability of intoxication ," says Felix Savino at UW - Madison. Many college students today see not just drinking but being drunk as their primary way of socializing. The reasons for the shift are complex and not fully understood. But researchers guess that it may have something to do with today's instant - satisfaction life - style--and young people tend to take into the extreme. While binge drinking isn't always deadly, it does have other, wide - ranging effects. Academics is one area where it takes a heavy _ (something paid, lost or suffered). Perhaps because alcohol increases aggression and affects judgement, it is also related to 25 percent of violent crimes and roughly 60 percent of vandalism on campus. Facing the many potential dangers, college campuses are searching for ways to reduce binge drinking.
Question: Why has "binge drinking" caused widespread concern?
Options: (A) Because it is directly responsible for the academic problem on campus. (B) Because it has claimed many young lives every year. (C) Because it has had harmful effects on the students' health and well - being. (D) Because it is in close connection with school violence.

C
