Input: Consider Input: Article: Consumers at the Whale Inside Dark Restaurant are led by a waiter with night - vision Goggles . Inside Dark Restaurant in prefix = st1 /Beijing, a table of 30 diners was getting quarrelsome."I'm touching your head!"said one, like a talkative child. "Who just said that?"another replied. Such voices floated across the 90-plus-seat restaurant, but no one could see who was talking, except the waiters, who were equipped with military-grade night-vision goggles. In the new conceptual dining, restaurants are turning off the lights to focus attention on the food. The trend seems to have started inZurichand has since spread all over the world, with diners sitting in _ rooms and, lately, being served by waiters in night-vision goggles. The idea is that by depriving one sense (sight), other senses are heightened. Darkness has other benefits. ''Chinese people tend to be shy,'' said Chen Long, who owns Whale Inside Dark, which opened in January. ''People have found it easy to break the ice here.'' The first dark restaurant, which opened inZurichin 1999, had a simple intention. The goal ''was creating jobs for the blind and handicapped people,'' said the manager. The concept has been popular in Paris, London,Sydneyand elsewhere, offering new variations on sight deprivation, by which people can experience a lot in a completely dark condition. In Beijing, the Whale Inside Dark Restaurant is not only about heightening the sense of taste, but lowering social inhibitions . It is popular with Internet daters, who met on matchmaking Web sites that are spreading throughout China. Diner for two is about 225 yuan, or $29 at 7.76 yuan to the dollar. Eating in the dark is not without its troubles. Instead of family-style dining, food is served on single-serving plates. When each dish arrives, the server guides your hand to the plate and offers helpful tips like, ''This course is eaten with a spoon.'' The style seems to be working . ''People feel a lot more comfortable when they can't be seen by others,'' said Mr. Chen, who is opening a second branch in Shang-hai, ''Couples get to know each other without seeing other's faces.''

Input: Consider Input: Article: China is a land of bicycles. At least it was back in 1992 when I traveled the country. Back then everyone seemed to be riding a bicycle. Millions of them, all black. Cars were rare. Yet since my arrival in Beijing last year, I've found the opposite is true. There are millions of cars. However, people still use their bicycles to get around. For many, it's the easiest and cheapest way to travel today. Bicycles also come in different colors---silver, green, red, blue, yellow, whatever you want. It's fun watching people biking. They rush quickly through crossroads, move skillfully through traffic, and ride even on sidewalks . Bicycles allow people the freedom to move about that cars just can't provide. Eager to be part of this aspect of Chinese culture, I decided to buy a bicycle. Great weather accompanied my great buy. I immediately jumped up on my bicycle seat and started home. My first ride home was orderly . To be safe, I stayed with a "pack" of bikers while cars on the streets came running swiftly out of nowhere at times. I didn't want to get hit. So I took the ride carefully. Crossing the streets was the biggest problem. It was a lot like crossing a major highway back in the United States. The streets here were wide, so crossing took time, skill and a little bit of luck. I finally made it home. The feeling on the bicycle was amazing. The air hitting my face and going through my hair was wonderful. I was sitting on top of the world as I passed by places and people. Biking made me feel alive.
Answer: Because they are convenient and inexpensive.

Output: According to the author, why are bicycles still popular in China today?

Input: Consider Input: Article: In recent years, especially during the l960s, there was much discussion about "the brain drain (, )," which dealt with the problem of students and learned people who left their own countries for other countries that offered better chances for study, research, and employment.For example, according to a report from U.N., between 1962 and l966 more than 50 percent of all engineering graduates of Iran and 14 percent of Iranian scientists left their country for work abroad.Over 30 percent of Chilean engineers and 15 percent of Turkish physicians also went to work in other countries.Probably the greatest brain drain occurred among young scientists who had gone abroad to study.Many of them had planned to return to their countries to teach but chose to remain in more industrialized nations where they were able to continue their work and their research in fields in which there were no job possibilities at home.The countries that attracted most of these scientists were the United States, Great Britain, Germany, France, Canada, and Australia. Recent studies show that the brain drain to the United States may be decreasing.Many foreign scientists are going home again, and in some cases American scientists are leaving the United States for employment in other countries.The main reasons are that good jobs are becoming fewer here, money for national research has been sharply cut, and university fellowships reduced too.However, in the field of medicine the drain to the United States still goes on.Today more than one of every five American doctors is foreign - born, and several thousand foreign doctors immigrate to the United States each year.Over eighty countries have asked the State Department to send students who are skilled in important fields such as medicine back home when their study programs are over.
Answer: Good housing.
Output: Which of the following is not the reason for "the brain drain"?
