Q: Article: The Olympic Games are seen as the greatest test of an athlete's ability and are supposed to celebrate the spirit of fair play. But in fact, sportsmen have been using drugs to cheat their way to victory since the Games first began. In the early years, athletes ate mushrooms and plant seeds to improve their performance. Nowadays, this kind of cheating has a name doping . Just last month, Britain's top sprinter Dwain Chambers and several American athletes tested positive for the drug THG. Until a coach secretly gave a sample of THG to scientists, no one knew how ho test for it. "We're like cops chasing criminals--athletes are always adapting and looking for areas we haven't investigated," said Jacquew de Ceaurriz, a French anti-doping expert. Since the first drugs test was carried out at the 1968 Olympics in Mexico City, many cheats have been caught out. The most famous case in history is that of Canadian sprinter Ben Johnson. He broke the 100 meters world record in winning gold at the 1988 Seoul Olympics. But days later, he tested positive for drug use, lost his gold medal and was banned from the sport. Five years later, he returned to action--only to be found positive again and banned forever. China has also had problems with drug cheats. At the 1994 Asian Games, 11 Chinese athletes--seven of them swimmers--tested positive for banned drugs. Sports organizations promised that cheating on this scale would not happen again. Experts are also worried that doping can damage a person's health. It is believed to increase the risk of liver and kidney diseases, and women may experience reproductive problems. As long as they can stay ahead of the scientists, it is unlikely the cheats will stop. But experts say there is a limit to what can be achieved and that athletes will not be able to change their bodies using gene technology. "For the moment, genetic doping does not exist," said de Ceaurriz. "Even in 10 or 15 years it will not be done easily--the scientific community will not let it happen."
Answer: Eating plant seeds.

A: Which of the following is not the way that some athletes cheat to their better sports achievements?

Q: Article: There is a growing problem of what to do with electronic waste such as old televisions, computers, radios, cellular telephones and other electronic equipment. Electronic trash, or e-waste, is piling up faster than ever in American homes and businesses. People do not know what to do with old televisions or computers, so they throw them in the trash. National Solid Wastes Management Association (NSWMA) state programs director Chaz Miller says the large amount of electronic waste Americans produce is not unexpected. The US Environmental Protection Agency (EPA) estimates more than 400 million consumer electronic items are dumped each year, and there is a push by more states to ban the waste from landfills and create recycling programs. They can be torn apart and sorted for useable parts. Mike Fannon who runs the plant in Baltimore, says, "There are a lot of valuable metals that can be recovered and reused instead of just putting them in the landfill, and in certain components, there are some materials that should not really be in the landfill," Fannon explains. Fannon says nearly 20 percent of electronic waste is recycled nationwide. Thirteen years ago, it was only about 6 percent. Recycling rates continue to rise as more communities have banned electronics from landfills in an effort to keep e-waste poisons like lead and mercury out of garbage dumps. This year, several states like Vermont imposed a ban on electronic waste in landfills. More than 25 other states have also adopted landfill bans, e-waste recycling programs or both. Chaz Miller says more can be done to boost electronic waste recycling. "We can do much better," noted Miller. "I think clearly our goal should be to do as well as we do recycling newspapers."
Answer: Old newspapers.

A: Which of the following does NOT belong to e-waste?

Q: Article: Researchers believe that the insect is better at managing congestion than humans. Ants are the most many type of animal on earth with brains that contain about 250,000 cells ---- the largest among insects. Now an intelligence expert Dr. Dirk Helbing says understanding more about ants could help solve one of the headaches of modern life -- road congestion. His team set up an "ant motorway" with two routes of different widths from the nest to some sugar syrup . Soon the narrower route soon became crowded . But when an ant returning along the crowded route to the nest met with another ant just starting out, the returning ant pushed the newcomer onto the other path. However, if the returning ant had enjoyed a trouble-free journey, it did not send the newcomer in a different direction. The result was that just before one route became _ , the ants had turned to another route and traffic jams never formed. The researchers also created a computer model of more complex ant networks with routes of different lengths. The team found that even though ants being sent in another direction sometimes took a longer route, they still got to the food quickly and efficiently. Dr. Helbing, of the Dresden University of Technology in Germany, said that while you cannot allow cars to meet with traffic coming in the opposite direction as a form of traffic control, you could do the next best thing and allow them to communicate. His plan is to force cars traveling in one direction to tell oncoming traffic what the conditions they are about to meet with-- so they can avoid that situation if necessary.
Answer: The ant will push the newcomer to the other route, so traffic jams won't form.

A:
If an ant returns along crowded route to the nest, how does the ant solve the traffic problem?
