Passage 2 Questions 6 to 10 are based on the following passage. Apart from the numerous benefits and conveniences people around the world can enjoy due to the Internet, there are also multiple drawbacks（缺陷）．There is one big problem almost any Internet user has encountered at least once in a lifetime-spam（垃圾邮件）．Unlike what people might think, spam is not just an annoying but harmless email message In fact, spam can be a dangerous tool capable of harming its receivers, and should be outlawed. Spam can cause real damage. If you wonder how a mere electronic letter can be harmful, first recall the usual contents of spam letters. Along with commercials and newsletters from electronic shops you have used just once, every email user is also at risk of receiving spam letter advertising pornography（淫秽内容），weapons, and other questionable content. Although it might be safe in the United States of America, the European Union, and some other western countries, it can be illegal in more religious countries-especially in Islamic states. A citizen of such a country who has received a spam letter with pornography can be thrown in jail for nothing. A person who never looked for such content might be accused of consuming it. This is not to mention child pornography, which is also distributed and advertised through spam messages. Having to deal with spam day by day can be stressful. Even though spam messages usually have an“unsubscribe”link, getting off a spammer’s list requires a number of actions, such as visiting the website, acknowledging unsubscription, sending confirmation letters, and so on. This might be not a problem in the case of being a target of just several spammers; however, usually Internet uses receive dozens of spam messages daily; unsubscribing from each of them is almost impossible. Many AOL users, who are now having hard times dealing with spam, report they are already close to the point when their mailboxes stop working. Spam can be harmful in yet another way. Rather often, spam emails contain viruses such as Trojans, worms, unblockable ads, and the like. Opening a message with such a program can instantly damage users’ computers. Spam is a tool for all kinds of frauds; for example, popular are inheritance frauds, when a user receives a personalized and seemingly trustworthy email from a lawyer informing them about inheriting a sum of money, or real estate, and requiring them to send some personal data for a final check. Spam often advertises low quality, fake, or misleading products; various self-improvement and plastic surgery services and products are also distributed through spam-no need to say they deal with more harm than use. All these facts speak in favor of the necessity to proclaim spam illegal.Which of the following is the drawback of the Internet according to the passage?
A.User can easily get personal date. B.It costs a lot of money to subscribe newsletters. C.Users may receive emails with questionable content. D.It’s inconvenient to receive electronic letters from the rural area.正确答案C
