[Q]: Article: On July 16th 1995, a new bookstore opened in the American city of Seattle. No one steps inside to buy anything. Yet, the store, if you could call it that, had sales last year of 7000 million dollars. Ten years ago, few people bought things over the Internet. Few thought it was safe. Amazon.com changed many people's minds. Ten years later, an estimated seven out of ten American adults have used a computer to buy something. Market researchers at ComScore Networks estimate online spending last year at 117,000 million dollars. That was for goods and travel services. The person who started Amazon, Jeff Bezos remains its leader. In the 1990s, he urged employees to help Amazon get big fast. Yet, Amazon invested in many similar businesses that failed. Amazon lost plenty of money. It did not make a profit until 2003. Its most recent profit and earnings report released last week was better than many market watchers had expected. Today people can buy not just books and music but also many other products through Amazon. It competes with eBay, which celebrates its 10th birthday in September. eBay calls itself "the world's online marketplace". It does not sell anything. Instead, it provides a way for others to sell goods and services. People who want to buy something make competing offers through online auctions. eBay has grown to include several other businesses. These include Paypal, a company that processes online payments. As online sellers grew, traditional stores saw the future. Today, stores from the smallest to the biggest sell on the Internet. These include the biggest of all, Wal-Mart.

[A]: Amazon.com and eBay are different in that _ .

[Q]: Article: Podcasting is like radio broadcasting, except that it uses the Internet. Anyone with a computer and a microphone can record a show about any subject. Anyone with a computer and an MP3 player can download the podcasts and listen. Podcasting does require some technical knowledge, but not very much. Many education-related podcasts are aimed at college students. But a growing number is created for, and by, students in middle school and high school. At mountain View Alternative High School in prefix = st1 /Centreville,Virginia, the students have spent several weeks preparing for their project. They have written their stories.

[Q]: Article: Is war unavoidable? Can war be prevented? History tells that there were wars, great or small, in every century, in every decade. Throughout the ages, from the Stone age to the Atomic Age, men have been fighting, first with swords and shields , then with guns and cannons, and now, hydrogen bombs and missiles are used for military purpose. But, in spite of all these, it is still my belief that war can be prevented and peace can be won, but it requires the effort of every one of us. I am sure that we would not like to experience another world war. If it ever happens, two-thirds of the world and much of the civilization which men have gained through time, patience and effort will be destroyed. Will then the remaining one-third of the world be able to survive on its own? Our task now is not to blame the past, but to plan for the future. If there is peace in the world, men can use their rockets to explore the mystery of space, their submarines to explore the depth of the sea, their missiles to deliver mails and their fine equipment to penetrate the jungles of Africa, instead of using them military. Governments can use their money to build more schools, so that more children can be educated to be useful citizens. Scientists can use atomic energy to propel steamships and planes. They can also design new machines to increase the production of goods and thus improve the way of living of the people. How can a peaceful world be achieved? It requires, in my opinion, the understanding and friendship between all people from all nations. Let no one suffer discrimination by reason of color, race, religion, or national origin. Let the rich support the poor and the strong help the weak. We know that neither peace nor such a dream world can come true in a day or a month. It may even take decades or centuries. But let us plan and begin now.
Answer: Understanding and Friendship
[A]:
The best title for this passage is _ .
