Article: Do you have a hobby--something you really enjoy doing in your spare time? Have you ever wondered what it would be like if you could spend more time on your hobby and less time at work? Maybe it's not an either/or situation. Perhaps you can do both at the same time. When choosing a career, one of the things you must consider is your interests. Why then do so many people not even think about their hobbies when a hobby is, in fact, an interest? Perhaps it's because even Webster's Dictionary defines a hobby as "a pursuit (,) outside one's regular occupation ". Maybe this is a rule you should break. After all, no one ever said your hobby had to stay separate from your occupation. In addition people are usually very skilled at their hobbies. The combination of interest and skill is a very compelling reason to choose a particular career. "Who's going to hire someone who loves making beaded jewelry?" you may ask yourself. Good question. Don't wait for someone to hire you. Start your own business. That may be the best way to combine your hobby with your career. Those with hobbies that involve creating things, i.e. jewelry, clothing, or pottery, may do well to sell those items on their own. Before you go forward with your plans, though, you should find out whether being an entrepreneur is for you. When you attempt to turn your hobby into a career, don't forget to do your homework. Even though you may have enjoyed training your pet birds to sing the national song, that doesn't mean you're suitable to be an animal trainer. Be sure to research your career choice completely. There may be aspects of it that just aren't for you. In that case, stick to your day job, as they say, and save your hobby for your free time.

Article: The most important holiday in spring, especially for Christians , is Easter. This Christian holiday is not on the same date every year, but it's always on a Sunday. It can be any Sunday between March 22 and April 25. Many people celebrate Easter by buying new clothes. Children celebrate by hunting for color1ed eggs that their parents have hidden around the house. People also give Easter baskets filled with candy and other goodies to one another to celebrate the day. But the holiday is more than new clothes and good things to eat. On Easter, many people go to church to celebrate Jesus' resurrection from the dead. Most people color1 them. Some people hide them. Others just eat them. But no matter what one does with Easter eggs, they are an important Easter tradition throughout the Western world. People from many different cultures celebrate Easter. In both America and Belgium, children look for Easter eggs hidden on lawns and in bushes. In America, children believe the eggs are hidden by the Easter bunny . But in Belgium, the hidden eggs are supposed to have fallen from church bells. In Bulgaria, red Easter eggs are lucky in churches; Bulgarian families also hit these Easter eggs together to see whose is the strongest. The winner looks forward to good fortune that year. Still dozens of other Easter traditions exist. In parts of Austria, for example, children sing from door to door and are rewarded with color1ful eggs.

Article: New rules will let millions of Americans know where more of their food comes from. The law is known as COOL -- Country of Origin Labeling . American congress first passed the law in 2002. Stores have had to label seafood by country of origin since 2005. But industry pressure delayed other requirements until last week. Products that must now be labeled include fresh fruits and vegetables, muscle meats and some kinds of nuts. But the rules are complex, and many foods are not included. For example, organ meats are free to be labeled. So are processed foods, including cooked or smoked foods. The same food may sometimes have to be labeled and other times not. Fresh or frozen peas, for example, have to be labeled but not canned peas. Foods that are mixed with other foods are also excluded. Mixed nuts, for example, do not need to be labeled. The same is true of a salad mix that contains different things like lettuce and carrots. Or a fruit cup that combines different fruits. Also, the law doesn't include restaurants and other food service organizations. Department of Agriculture officials say the law is really meant for larger grocery stores. The United States has imported more and more food in recent years to save money and expand choices. Country-of-origin labeling has become more common lately but has still been limited in many stores. Food safety is one reason why some shoppers pay close attention to where foods came from. For example, when a large number of people recently got sick from salmonella , officials blamed peppers from Mexico. Yet the last big food scare involved spinach grown in California. But labeling is also a way for people to know they are getting what they want. Some want to buy local foods or foods from a particular country. The country-of-origin labeling law gives stores 30 days to correct any violations that are found. Stores and suppliers that are found to be deliberately violating the law could be fined 1,000 dollars per violation. Federal inspectors are not to take action to enforce the law for six months to give time for an education campaign. Some food safety activists say they are generally pleased with the law. They call it a good step that will give people more useful information.
Question: Why has more and more food been imported to the United States in recent years?
Options: (A) It is economical and provides people with more choices. (B) Foreign food is of higher quality than native food. (C) Americans need more and more food recently. (D) The United States is short of food supply.
