[Q]: Article: China's auto production is expected to grow by 20 percent in 2005 to 6 million vehicles , possibly passing Germany as the world's No. 3 producer. China is the world's-fastest-growing auto market as rising incomes make it possible for millions to buy their cars. Foreign automakers are investing billions of dollars in expanding production in China. Germany produced 5.5 million vehicles in 2004, the No. 3 producer behind the United States and Japan. London is quickly becoming a major cycling city after the terrorist ( ) bombings on London's subway and bus system July 7, which killed 52 people. London Mayor Ken Livingstone wants to increase cycling 80% by 2010. "Cycling is the fastest, cheapest, most healthy and environmentally friendly way to get around London, and more and more people are taking it up," Livingstone said. "The number of cyclists has doubled over the last five years, while those killed or seriously injured has fallen by 40%." Under the London Cycling Action Plan, Livingstone hopes to make London a world-class cycling city to reduce congestion and pollution. London now has 273 miles of bike roads, half built since 2000. The goal is 560 miles by 2010.

[Q]: 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.
[A]: According to the author, why are bicycles still popular in China today?

[Q]: Article: The gray wolf used to live in most of the northern United States, including Colorado. In fairy tales, wolves can be pretty mean, but in real life, wolves are shy animals that are afraid of people. They are predators of deer, elk and antelope. But as more people settled in the country, they killed off many of them, so wolves started eating the cattle and sheep that the settlers brought with them. Because the settlers needed those cattle and sheep for their own families, and because many people are afraid of wolves, people started killing wolves until they became endangered. Many places would even offer money to anyone who would kill a wolf. The last wolf in Colorado was shot 50 years ago. Now, the U.S. Department of Fish and Wildlife would like to see wolves reintroduced into their natural homes. This is happening already in Minnesota, but not in Colorado yet. There are lots of deer and elk in the Colorado mountains for them to eat now. In fact, many people feel that having the wolves back would be a help to the deer and elk herds . Without enough natural enemies, the herds get too big. Also, wolves and other predators usually catch the oldest or the sickest deer, so maybe they could help keep the other deer from getting sick and dying, too. But for ranchers , will the wolves come after cattle if there are plenty of deer to eat? It's hard to know. In Minnesota, they offer ranchers money to pay for animals that are known to have been killed by wolves. That way, the wolves have a chance, but the ranchers don't lose too much money. www.ks5u.com If you want to find out more about how to help wolves come home, click here.
