Input: Consider Input: Article: It is amazing to note that the Internet is still such a new device, and yet it is one of the fastest and most powerful media tools. But think about it for a moment. On the Internet, a big online company can be run by two guys out of their garage. So it is only reasonable that people shopping on the Net would be a little _ of the security levels. Internet giants such as Microsoft knew consumer confidence was the key to getting virtual shopping off the ground, and they work hard to make people feel safe to shop online. Credit card companies, too, quickly saw the potential for Internet shopping, and have installed things like online shopping insurance for people. If you ever have a problem with your online credit purchases, many credit card companies will happily refund your money and then set their claws on the company that wronged you. Now that's buying power! There are other bonuses for online shoppers, of course. No line-ups, for one. No annoying mall shopping carts with broken wheels and kids crying because their parents won't get them what they want. When shopping online, consumers can sit down, have a coffee, and wear their slippers, not have to worry about their hair or parking and just click through sale after sale. Comparison shopping couldn't be any easier. And thanks to courier companies getting in on the act, you never need wait longer than a day or two to get those all important purchases delivered right to your door. No wonder so many companies are shaking their heads at traditional advertising and instead looking to the "virtual" world to attract online shoppers.
Question: _ leads to consumers' trust in online shopping.
Options: (A) Shopping law (B) Shopping convenience (C) Internet access (D) Shopping security

Input: Consider Input: Article: A senior United Nations Children's Fund (UNICEF) official on May 29 praised China for its remarkable achievements in children s welfare. A. H. M. Farook, UNICEF's operations area officer for China and Mongolia said that China "can be very satisfied to tell the whole world what can be done with limited resources to help its children to grow healthily and happily." China's child population makes up one-filth of the world's total. "The reason behind the tremendous achievement is China's long tradition of caring for children home at home and in society." he said. "What's more is that Chinese people have always given special attention to children who are in special need." The UN official made the remarks when addressing a group of 50 children and staff from the Beijing Children's Welfare Home at the Shangri-la Hotel, Beijing. The hotel invited the orphans to share snacks, sing, dance and play games at a park inside the hotel for a "Share the Sunshine" party, as a prelude to celebrations to mark the Children's Day. The Beijing children s Welfare Home, set up soon after New China, was founded in 1949, has at present more than 400 children. A leading official of the welfare institution said that the children live a happy life and that the agency spends about 400 yuan a month for an average orphan. An average Chinese worker earned 440 yuan a month during the first quarter this year. Gu Xiaojin, deputy secretary-general of the China Youth Development foundation (CYDF), said people from all walks of life had contributed to the welfare of the Chinese children. She said that CYDF set up the Project Hope in 1989, which calls on people across the country to donate money to help poor children to continue their schooling. By the end of last year, she said, CYDF had collected nearly 700 million yuan in donations, which has helped the establishment of 2, 074 Hope primary schools and enabled more than 1.25 million dropouts to return to school classrooms. Three "Hope Stars" also attended the party. They were model teenagers chosen among students who are economically supported by the Project Hope to further their nine-year compulsory studies in the poverty-stricken regions. They will be torchbearers for the Chinese Team for the upcoming Atlanta Olympic Games this year.

Input: Consider Input: Article: Harvard University in the United States has been ranked as the university with the best "reputation" in the world. The Times Higher Education magazine has listed 200 top universities all over the world based on how they are regarded by a group of international college teachers. That is to say the list measures how universities are regarded, rather than how they actually performed. A subjective, word-of-mouth quality such as "reputation" has genuine economic value for universities, said Simon Marginson, professor of higher education at the University of Melbourne in Australia. "Reputation is not just an impression, though it might be not as reliable as performance by objective indicators ," said Prof Marginson. Based on the views of 13,000 college teachers around the world, it confirms the power of the big US universities, which _ this list. Seven of the top 10 are US universities, headed by Harvard and Massachusetts Institute of Technology (MIT). Furthermore, 14 of the top 20 are from the US. Cambridge is the highest ranking UK university in the list, in third place, with Oxford ranked as sixth. For students applying to university, reputation might be hard to quantify, but was an important part of the attractiveness, said the president of Cambridge University's students' union, Rahul Mansigani. "Reputation makes a huge difference. If there is an idea that somewhere is great, it will get lots of good people applying whether it's true or not. Factors such as a sense of history and the presence of outstanding college teachers were part of the reputation of Cambridge," he said.
