Input: Consider Input: Article: One Halloween a little boy and his friend went out for a fun night of trick-or-treating. At first everything was great. They were getting lots of candy as they went from house to house, but then they saw a house which they hadn't been to before. It was a very spooky house. Being young and brave, they decided to go up to the door and knock. After all, scary houses might have the best candy! As they walked up the long winding path, they saw things that chilled them to the bone! They heard sounds that frightened them. Maybe they should turn back. But the little boys, being very brave, just wanted to see what was in that house, so they went on, not deterred by the things they heard or saw. As they slowly made their way up to the door, they imagined what might be inside. Maybe it would be a witch or maybe a ghost! After knocking several times, the door slowly creaked open. To their surprise, a monster slowly came out to greet them. They were so scared that they couldn't move! What could they do? Then the little boy had an idea. He said, "Trick or treat!" Then the big scary monster, much to the kids'surprise, reached over and brought out a huge bowl of the best candies they had never seen. Wow, the kids thought, this was great! It turned out that the house was decorated for Halloween, and the big scary monster was just wearing a costume, just like the kids. Since they were the only kids, and were brave enough to go to the scary house, they could take as much candy as they wanted.

Input: Consider Input: Article: Last year, over 206,000 students from the United States studied abroad. Does that number surprise you? These students already know the benefits of studying abroad. You may be wondering why you should study abroad. Here are some answers for you. * Timing The absolutely best time in your life to study abroad is when you are in college. If you miss this opportunity, it's almost impossible for you to do it later in life. * To gain cross-cultural experience Life overseas makes you see your everyday world in a whole new light. You don't even realize it, but our culture shapes the way we view the world and affects us every minute of the day. Differences in culture are more than just differences in language, food, clothing and art. * To improve your communication skills and your self-confidence People who study abroad tend to be willing to take risks, willing to put themselves in unusual situations, and able to solve problems. * To become more fluent in a language or to learn a new language The world market is becoming smaller, and many companies require a second language. Foreign languages are not only valuable in the job market but also valuable in the real world. * For the adventure Travel to other cities within your host country and around neighboring countries. As you get to know your new classmates, roommates, and host family, you will gain a unique view on the host culture. Discover the differences and, more importantly, the many similarities between your worlds. The friendships you make will last long after the program. * To learn more about yourself Find out who you really are. What are your limits? How do you overcome the difficulties you've never _ before? How independent are you? These questions are hard to answer until you are removed from your usual surroundings. After solving difficult problems on your own overseas, you'll find that almost nothing will confuse you at home. Students who study abroad commonly report that their study abroad experience actually changed their lives.
