PROBLEM: 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.

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

PROBLEM: Article: As one of the world's oldest holidays, Halloween is still celebrated today in several countries around the globe, but it is in North America and Canada that it maintains its highest level of popularity. Every year, 65% of Americans decorate their homes and offices for Halloween. Halloween is the holiday when the most candy is sold and is second only to Christians in terms of total sales. Austria In Austria, some people will leave bread, water and a lighted lamp on the table before retiring on Halloween night. The reason for this is that it was once believed such items would welcome the dead souls back to earth on a night which for the Austrians was considered to be brimming with strong cosmic energies. Belgium The Belgians believe that it is unlucky for a black cat to cross one's path and also unlucky if it should enter a home or travel on a ship. The custom in Belgium on Halloween night is to light candles in memory of dead relatives. Canada Modern Halloween celebrations in Canada began with the arrival of Scottish and Irish immigrants in the 1800s. Jack- O- Lantern is carved and the festivities include parties, trick-or-treating and the decorating of homes with pumpkins and corn stalks. France Unlike most nation of the world, Halloween is not celebrated by the French in order to honor the dead and departed ancestors. It is regarded as an "American" holiday in France and was unknown in the country until around 1996.
