But the truth is, even here in Singapore, security cannot be taken for granted. It is a small nation that has no natural resources to speak of, even something as basic as water is constantly threatened to be cut off by Malaysia. Months after the September 11thattacks on US oil, a plot to bomb American soldiers near their military base in Singapore was uncovered by the local authorities. The United Nations has tried for more than half a century to architect peace for the world. But it has clearly failed. The grand horrors of the World Wars may have stopped but only in the forms they had existed before. When the enemy is unseen and there are no front lines, have we in fact created a more peaceful and secure place? Where have we gone wrong? Perhaps it is because the international body has never understood that peace was, is, and will never be something it can manage. Not recognizing this truth, the methods it provides are often short-lived and some even dangerous. Solutions for threatening situations tend to require the countries to carry out economic and political reforms so that they will become idealized democratic society like America or Britain. The UN fails to consider that hundreds of years of evolution gave rise to these strong democracies. So the result is further chaos and corruption, worse for all. Actually, an international organization or a government cannot possess peace to give away, but there are those who do possess it. Those who own peace are us, as individuals who cherish life, not our own but all others'. The act of achieving peace lies in us when we choose to respect social and cultural differences and appreciate that all our lives are fragile. Question: It can be inferred from the passage that _ . Options: A: political and economic reforms cause less terrible results B: democracy is a long process C: the horrors of World War don't exist. D: those who value their lives possess peace

Many banks say that their business is "untouched by human hands" and therefore safe. But they have no thought that the growing number of computer crimes show they can be used to steal. Computer criminals don't use guns. And even if they are caught, it is hard to punish them because there is often no proof. A computer cannot remember who used it. It simply does what it is told. The head teller at a New York City bank used a computer to steal more than one and a half billion dollars in just four years. No one noticed this because he moved the money from one account to another. Each time a customer whose money he had stolen questioned the balance in his account, the teller said it was a computer mistake, then replaced the missing money from someone else's account. This man was caught at last. Some workers use the computer's power to punish their bosses they consider unfair. Recently, a large company fired its computer record assistant for reasons that were connected with her personal life rather than her job. She was given thirty days notice. In those thirty days, she stole all the company's computerized records. Most computer criminals have been common workers. Now police wonder if this is "the tip of iceberg". As one official says, "I have the feeling that there is more crime out there than we are catching. What we are seeing now is all so poorly done. I wonder what the real experts are doing--the ones who really know a computer works." Question: Business in many banks is declared to be safe because _ . Options: A: paperwork is no longer needed B: computers are honest C: people are not allowed to work there D: it is done through computers

*Question*
Read the article and select the best answer. Article: There's no shortage of web sites offering deals-everything from daily deals to members-only private sales.But when it comes to real jaw-dropping deals, there's one company that seems to have figured out a out a way to really deliver. The company is called QuiBids and they auction the hottest, in-demand electronics like Apple ipads and ipods, as well as other items like gift cards from the top retailers .Unlike other sites, the prices people pay are nowhere near retail.How low are the prices? $33.84 for a new Apple ipad 32 GB(retail $600) $22.10 for a new Nikon D90 Digital SLR Camera(retail $1070) Our first reaction on seeing these prices was disbelief.After all, how cold QuiBids possibly afford to sell these items for so little-surely they must be losing a lot of money. That's where its unique business model comes into play.You see, for every bid a buyer places for an item on QuiBids, the company collects a small fee from the bidder.The fee to bid is only about 60 cents, but based on the volume of sales and bids, the company is able to collect enough to make up for the ridiculous prices the items sell for. But best of all, participating in the QuiBids auction is incredibly fun.Because each each bid costs a little to place, shoppers can strategize when to place their bids.Each auction has a strict time limit.When you place your bid, the system adds a little time to the auction to see if any other bids cone in.If you have the winning bid when the cock runs out-you win the item for that price. But the best part of Quibids may be the "Buy-It-Now"feature.This allows bidders who did not win an auction to still buy the product they want and apply the cost of the bids they placed as a discount on the regular product price. So you still get the item and the bids you placed previously in the auction don't cost you anything! Question: According to the text , the success of Quibids mainly lies in _ . Options: A: the change in people's shopping model B: how its buying and selling is conducted C: the quality of the goods and service D: their willingness to risk losing money
